0000006201-26-00001462016201AALAmerican Airlines Group Inc.10-K2026-02-182025-12-31https://www.sec.gov/Archives/edgar/data/6201/000000620126000014/0000006201-26-000014-index.htmhttps://www.sec.gov/Archives/edgar/data/6201/000000620126000014/aal-20251231.htmread1Business1Item 1. BUSINESS Overview American Airlines Group Inc. (AAG), a Delaware corporation, is a holding company and its principal, wholly-owned subsidiaries are American Airlines, Inc. (American), Envoy Aviation Group Inc., PSA Airlines, Inc. (PSA) and Piedmont Airlines, Inc. (Piedmont). AAG was formed in 1982, under the name AMR Corporation (AMR), as the parent company of American, which was founded in 1934, with roots tracing back to an air mail carrier in the Midwestern United States in 1926. AAG’s and American’s principal executive offices are located at 1 Skyview Drive, Fort Worth, Texas 76155 and their telephone number is 682-278-9000. Airline Operations Together with our wholly-owned regional airline subsidiaries and third-party regional carriers operating as American Eagle, our primary business activity is the operation of a major network air carrier, providing scheduled air transportation for passengers and cargo through our hubs in Charlotte, Chicago, Dallas/Fort Worth, Los Angeles, Miami, New York, Philadelphia, Phoenix and Washington, D.C. and partner gateways, including in London, Doha, Madrid, Seattle/Tacoma, Sydney and Tokyo (among others). We provide service to over 350 destinations around the world, and in 2025, approximately 224 million passengers boarded our flights. In 2025, we launched more than 60 new routes, including to trans-Atlantic destinations such as Spain, Italy and Greece. We also announced over 20 new routes for customers to explore in 2026, including our first trans-Atlantic route to be flown by the Airbus A321XLR from New York to Edinburgh, Scotland. As of December 31, 2025, we operated 1,013 mainline aircraft supported by our wholly-owned regional airline subsidiaries and third-party regional carriers, which together operated an additional 567 regional aircraft. See Part I, Item 2. Properties for further discussion of our mainline and regional aircraft and “Regional” below for further discussion of our regional operations. American is a founding member of the oneworld® Alliance, which brings together a global network of 15 world-class member airlines and their affiliates, working together to provide a superior and seamless travel experience. See “Distribution and Marketing Agreements” below for further discussion on the oneworld Alliance and other agreements with domestic and international airlines. See Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations – “2025 Financial Overview,” “AAG’s Results of Operations” and “American’s Results of Operations” for further discussion of AAG’s and American’s operating results and operating performance. Also, see Note 1(m) to each of AAG’s and American’s Consolidated Financial Statements in Part II, Items 8A and 8B, respectively, for passenger revenue by geographic region and Note 13 to AAG’s Consolidated Financial Statements in Part II, Item 8A and Note 12 to American’s Consolidated Financial Statements in Part II, Item 8B for segment disclosures. Regional Our regional carriers provide scheduled air transportation under the brand name “American Eagle.” The American Eagle carriers include our wholly-owned regional carriers Envoy Air Inc. (Envoy), PSA and Piedmont, as well as third-party regional carriers including Republic Airways Inc. (Republic) and SkyWest Airlines, Inc. (SkyWest). Our regional carriers are an integral component of our operating network. We rely heavily on regional carriers to serve small markets and also to drive connecting traffic to our hubs from markets that are not economical for us to serve with larger mainline aircraft. In addition, regional carriers offer complementary service in many of our mainline markets. All American Eagle carriers use logos, service marks, aircraft paint schemes and uniforms similar to those of our mainline operations. In 2025, 57 million passengers boarded our regional flights, approximately 42% of whom connected to or from our mainline flights. Our regional carrier arrangements are principally in the form of capacity purchase agreements with our third-party regional partners and similar arrangements with our wholly-owned affiliates which provide that all revenues, including passenger, in-flight, ancillary, mail and freight revenues, go to us. We control marketing, scheduling, ticketing, pricing and seat inventories. In return, we agree to pay predetermined fees to these airlines for operating an agreed-upon number of aircraft, without regard to the number of passengers on board. In addition, these agreements provide that we either reimburse or pay 100% of certain variable costs, such as airport landing fees, fuel and passenger liability insurance. 8 Table of Contents Cargo Our cargo division provides a wide range of freight and mail services, with facilities and interline connections available across the globe. In 2025, we served over 20,000 unique origin and destination pairs, transporting approximately 1.0 billion pounds of time-sensitive freight and mail throughout our network. We continue to focus on enhancements that enable us to better serve our customers, including moving to a new facility at London Heathrow Airport (LHR) to support further growth in this key market and expanding our digital offerings, which provide greater efficiency, increased accuracy, 24/7 access to search schedules, and the ability for our customers to check availability, retrieve rates and make bookings. Distribution and Marketing Agreements Passengers can purchase tickets for travel on American and American Eagle through several distribution channels, including our website (www.aa.com), our mobile app and our reservations centers, and through third-party distribution channels, including conventional travel agents, travel management companies and online travel agents (OTAs) (e.g., Expedia, including its booking sites Orbitz and Travelocity, and Booking Holdings, including its booking sites Kayak and Priceline). Additionally, American utilizes new distribution technologies such as IATA New Distribution Capability (NDC) technology, which we distribute our content to third parties through aggregators (e.g., Amadeus, Sabre, Travelport and Travelfusion) or through direct connections. NDC technology provides customers access to enhanced content and functionality, providing a simplified booking experience, and enabling us to provide more relevant, tailored offers to customers. To remain competitive, we will need to successfully manage our distribution costs and rights, increase our distribution flexibility and improve the functionality of our distribution channels, while maintaining an industry-competitive cost structure. For more discussion, see Part I, Item 1A. Risk Factors – “We rely on third-party distribution channels and must effectively manage the costs, rights and functionality of these channels.” Member of oneworld Alliance American is a founding member of the oneworld Alliance, which currently includes Alaska Airlines, British Airways, Cathay Pacific, Fiji Airways, Finnair, Iberia, Japan Airlines, Malaysia Airlines, Oman Air, Qantas Airways, Qatar Airways, Royal Air Maroc, Royal Jordanian Airlines and SriLankan Airlines. Hawaiian Airlines is expected to join the oneworld Alliance in 2026. The oneworld Alliance links the networks of member carriers and their respective affiliates to enhance customer service and provide smooth connections to the destinations served by the alliance, including linking member carriers’ loyalty programs and providing reciprocal access to the carriers’ airport lounge facilities. Joint Business Agreements and Other Cooperation Agreements American has established a transatlantic joint business with British Airways, Aer Lingus, Iberia and Finnair, a transpacific joint business with Japan Airlines and a joint business covering Australia and New Zealand with Qantas Airways. Joint business agreements enable the carriers involved to cooperate on flights between particular destinations and allow pooling and sharing of certain revenues and costs, enhanced loyalty program reciprocity and cooperation in other areas. Joint business agreements have become a common approach among major carriers to address key regulatory restrictions typically applicable to international airline service, including limitations on the foreign ownership of airlines and national laws prohibiting foreign airlines from carrying passengers beyond specific gateway cities. We also have established strategic alliances with Alaska Airlines and Qatar Airways that deliver to our customers an improved network offering and enhanced loyalty program reciprocity, among other benefits. In July 2010, in connection with a regulatory review related to our transatlantic joint business, we provided certain commitments to the European Commission (EC) regarding, among other things, the availability of take-off and landing slots at LHR or London Gatwick Airport (LGW). The commitments accepted by the EC were binding for 10 years. In anticipation of both the exit of the United Kingdom (UK) from the European Union (EU), commonly referred to as Brexit, and the expiration of the EC commitments in July 2020, the United Kingdom Competition and Markets Authority (CMA), in October 2018, opened an investigation into the transatlantic joint business. In September 2020 and April 2022, the CMA adopted interim measures that extend the EC commitments until March 2026 in light of the uncertainty and other impacts resulting from the COVID-19 pandemic. In August 2025, the CMA accepted binding commitments and closed the case. The commitments will replace the prior interim measures. The foregoing arrangements are important aspects of our international network, and we are dependent on the performance and continued cooperation of the other airlines party to those arrangements. 9 Table of Contents Marketing Relationships To improve access to each other’s markets, various U.S. and foreign air carriers, including American, have established marketing agreements with other airlines. These marketing agreements vary in scope and are intended to provide enhanced customer choice by means of an expanded network with loyalty program participation, but do not involve the same level of cooperation as our joint businesses or strategic alliances. As of December 31, 2025, in addition to the relationships described above, American had codeshare, marketing and/or loyalty program relationships with Air Tahiti Nui, China Southern Airlines Company Limited (China Southern Airlines), Etihad Airways, GOL Linhas Aéreas Inteligentes S.A. (GOL), Gulf Air, Hawaiian Airlines, IndiGo, JetSMART, Jetstar, Jetstar Japan, Korean Air Lines, Philippine Airlines, Porter Airlines and Vueling Airlines. AAdvantage® Program Our AAdvantage program was established to enhance passenger loyalty by offering benefits and rewards to travelers for their continued patronage with American and our partners. AAdvantage members enjoy exclusive benefits and earn AAdvantage mileage credits (miles) for flying on eligible tickets on American, American Eagle, any oneworld Alliance airline or other partner airlines. Along with AAdvantage miles, members also earn Loyalty Points, which unlock AAdvantage status and rewards for our AAdvantage members. For every dollar spent by flying on an eligible American ticket, members earn mileage credits, and AAdvantage Gold®, AAdvantage Platinum®, AAdvantage Platinum Pro® and AAdvantage Executive Platinum® status holders earn additional bonus mileage credits of 40%, 60%, 80% and 120%, respectively. Members also earn mileage credits and Loyalty Points by using the services of more than 1,000 non-flight partners, such as our co-branded credit cards, certain hotel, car rental and cruise companies and shopping and dining partners. The AAdvantage program in general, and our co-branded credit card programs in particular, are material assets of our business and have become increasingly important to our company over time. Starting in 2026, Citibank N.A. (Citi) became the exclusive issuer of the AAdvantage co-branded credit card portfolio in the U.S. Cash payments from co-branded credit card and other partners were $6.2 billion and $6.1 billion during 2025 and 2024, respectively. Cash remuneration in 2024 included a one-time cash payment related to the new co-branded credit card agreement announced in December 2024. In July 2025, we extended our agreement with Mastercard pursuant to a new 10‑year contract, under which Mastercard remains the exclusive payment network for our AAdvantage co‑branded credit cards. We will enhance our AAdvantage program using Mastercard’s payments infrastructure and analytics to deliver more personalized offers to AAdvantage members, optimize rewards and provide seamless, secure transactions. Mastercard’s technology will power real-time fraud detection and optimize payments from booking to in flight. Additionally, AAdvantage members will have new ways to redeem miles for Mastercard’s Priceless Experiences. Mileage credits can be redeemed for travel and upgraded experiences on American and participating airlines, access to our Admirals Club® and Flagship Lounges®, or for other non-flight awards, such as car rentals, hotel stays, cruises and retail goods from our program partners. Travel awards are available on all flights operated by American and, subject to capacity-controlled seating, on flights operated by our partners. A member’s mileage credits generally do not expire if that member has any type of qualifying activity at least once every 24 months or if the AAdvantage member is the primary holder of a co-branded credit card. AAdvantage members qualify for status over a 12-month period beginning on March 1 of each year by earning Loyalty Points. Status members can enjoy additional travel benefits of the AAdvantage program, including complimentary upgrades, checked bags, and Preferred and Main Cabin Extra seats, as well as priority check-in, security, boarding and baggage delivery when traveling on American, American Eagle, any oneworld Alliance airline or select partner airlines. In addition, AAdvantage members can unlock benefits, rewards and choices before, between and beyond the traditional status tiers with Loyalty Point Rewards. AAdvantage Business, our business loyalty program, rewards both eligible companies with AAdvantage miles and their travelers with additional Loyalty Points when booking business travel. In 2025, the AAdvantage program was recognized for Best Customer Service and Best Redemption Ability in the Americas and the Citi®/AAdvantage® Platinum Select® World Elite Mastercard® co-branded credit card was recognized as the Best Loyalty Credit Card in the Americas at the 2025 Freddie Awards. The Freddie Awards recognize the best travel loyalty programs across the world and are based on votes from travelers. Under our agreements with AAdvantage members and program partners, we reserve the right to change the terms of the AAdvantage program at any time and without notice. Program rules, partners, special offers, awards and requisite mileage levels for awards are subject to change. 10 Table of Contents During 2025, our members redeemed approximately 18 million awards, including travel redemptions for flights and upgrades on American, American Eagle and other air carriers, as well as redemption of car and hotel awards, club memberships and merchandise, among others. Approximately 9% of our 2025 total revenue passenger miles flown were from award travel. See Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations – “Critical Accounting Policies and Estimates” for more information on our loyalty program. Industry Competition Domestic The markets in which we operate are highly competitive. On most of our domestic nonstop routes, we face competing service from other domestic airlines, including major network airlines, low-cost carriers and ultra-low-cost carriers such as Alaska Airlines, Allegiant Air, Delta Air Lines, Frontier Airlines, Hawaiian Airlines, JetBlue Airways, Southwest Airlines, Spirit Airlines and United Airlines. Between cities that require a connection, where the major airlines compete via their respective hubs, competition is significant. In addition, we face competition on some of our connecting routes from airlines operating point-to-point service. We also compete with all-cargo and charter airlines and, particularly on shorter segments, ground and rail transportation. In general, beyond nonstop city pairs, carriers that have the greatest ability to seamlessly connect passengers to and from markets have a competitive advantage. In some cases, however, foreign governments limit U.S. air carriers’ rights to transport passengers beyond designated gateway cities in foreign countries. In order to improve access to domestic and foreign markets, we have arrangements with other airlines including through the oneworld Alliance, joint business agreements and other cooperation agreements and marketing relationships, as further discussed herein. On all of our routes, pricing decisions are affected, in large part, by the need to meet competition from other airlines. Price competition occurs on a market-by-market basis through price discounts, changes in pricing structures, fare matching, targeted promotions and loyalty program initiatives. Airlines typically use discounted fares and other promotions to stimulate traffic during normally weak travel periods, when they begin service to new cities, when they have excess capacity, to generate cash flow, to maximize revenue per available seat mile or to establish, increase or preserve market share. Most airlines will quickly match price reductions in a particular market, and we have often elected to match discounted or promotional fares initiated by other air carriers in certain markets in order to compete in those markets. In addition, we face pricing pressures from so-called ultra-low-cost carriers, such as Allegiant Air, Frontier Airlines and Spirit Airlines, which compete in many of the markets in which we operate. In addition to price competition, airlines compete for market share by increasing the size of their route system and the number of markets they serve. The American Eagle regional carriers increase the number of markets we serve by flying to smaller markets and providing connections at our hubs. Many of our competitors also own or have agreements with regional airlines that provide similar services at their hubs and other locations. We also compete on the basis of scheduling (frequency and flight times), availability of nonstop flights, on-time performance, type of equipment, cabin configuration, amenities provided to passengers, loyalty programs, the automation of travel agent reservation systems, onboard products, health and safety, sustainability initiatives and other services. International In addition to our extensive domestic service, we provide international service to Canada, Mexico, the Caribbean, Central and South America, Europe, Qatar, China, Japan, South Korea, India, Australia and New Zealand. In providing international air transportation, we compete with other U.S. airlines, foreign investor-owned airlines and foreign state-owned or state-affiliated airlines. Competition has also been increasing from low-cost airlines executing international long-haul expansion strategies, a trend we expect to continue, in particular with the introduction of long-range narrowbody aircraft. In order to increase our ability to compete in the market for international air transportation service, which is subject to extensive government regulation, U.S. and foreign carriers have entered into bilateral and multilateral marketing relationships, alliances, cooperation agreements and joint business agreements to exchange traffic among each other’s flights and route networks. See “Distribution and Marketing Agreements” above for further discussion. 11 Table of Contents Sustainability We aim to run a resilient, profitable enterprise that will thrive over the long term. Our strategy focuses on protecting the safety of team members and customers, attracting and developing top talent, providing a world-class travel experience and positioning American to compete in a low-carbon economy. Safety The safety of our customers and team members is a top priority. Our approach to safety is guided by our Federal Aviation Administration (FAA)-approved safety management systems (SMS), an organization-wide approach to identifying and managing risk. Each SMS is comprised of four components: Safety Policy, Safety Risk Management (SRM), Safety Assurance and Safety Promotion. Our Safety Policy sets safety objectives while striving to comply with applicable regulatory requirements and laws in the countries where we operate, and it establishes standards for acceptable operational behaviors. The SRM element of our SMS provides a decision-making process for identifying hazards and mitigating risk based on a thorough understanding of our systems and their operating environment. We employ SRM whenever there is a change to our processes, procedures or operations, such as the delivery of new aircraft. The Safety Assurance component specifies how we validate the effectiveness of risk controls and the performance of the SMS using data to conduct quality assurance and internal oversight. Lastly, the Safety Promotion component of our SMS includes communications and training to keep heightened awareness among team members to identify and report potential safety concerns. Our People The airline business is labor intensive, and our team members are critical to delivering for our customers. The operational complexity of our business requires a team of personnel trained and experienced in a variety of technical areas such as flight operations, ground operations, safety and maintenance, customer service and airline scheduling and planning. Fostering a culture where our team members feel supported to take care of our customers is critical to our success. To do this, we must continue to hire the best and the brightest, ensure that people from all backgrounds are aware of the opportunities that exist in aviation, and create a culture where everyone can reach their full potential and thrive. In 2025, mainline and regional salaries, wages and benefits were our largest expense and represented 38% of our total operating expenses. As of December 31, 2025, we had approximately 139,100 active full-time equivalent employees, approximately 86% of whom were represented by various labor unions responsible for negotiating the collective bargaining agreements (CBAs) governing their compensation and job duties, among other things. Talent Development We focus on providing our team members with the tools, training and resources they need to do their best work. We maintain a suite of programs aimed at helping our people develop the skills and experience they need to succeed in their roles and build rewarding, long-term careers within our company. Our Culture We seek to create a workplace where all perspectives and experiences are welcomed, valued and encouraged and where every individual, regardless of their national origin, religion, race, gender, sexual orientation or background, not only knows they belong, but that they can thrive at our company. Our goal is to make culture a competitive advantage so people will want to work with us, fly with us and invest in us. We believe in: •Hiring, engaging and retaining the best and the brightest talent for growth; •Delivering excellence in our operations to serve and expand our global markets; •Striving to have our teams build connections and trust with all who fly with us; and •Driving industry innovation to build competitive advantages. 12 Table of Contents Competitive Pay and Comprehensive Benefits We seek to offer competitive pay, comprehensive benefits and a wide variety of resources designed to support the physical, behavioral and financial well-being of our team members and their families, including medical coverage that is intended to be affordable and flexible along with healthcare navigation and support tools. Our internal recognition programs give team members and customers the opportunity to show their appreciation for a job well done, including through our Nonstop Thanks program whereby team members can award each other points for exceptional service or as an expression of gratitude. Recognition points earned through the Nonstop Thanks program can be redeemed for items in an online catalog. In 2025, our team members were recognized by customers, peers and company leaders approximately three million times. Additionally, approximately 1,000 peer nominations were submitted for the annual Circle of Excellence, the highest honor that we bestow upon our team members for their career achievements. Our future success depends in large part on our ability to attract, develop and retain highly qualified management, technical and other personnel. We may not be successful in attracting, developing or retaining key personnel or other highly qualified personnel. In addition, competition for skilled personnel has intensified and may continue to intensify if overall industry capacity continues to increase and/or we were to incur attrition at levels higher than we have historically. For more discussion, see Part I, Item 1A. Risk Factors – “The loss of key personnel whom we depend on to operate our business, or the inability to attract, develop and retain additional qualified personnel could adversely affect our business.” Labor Relations Labor relations in the air transportation industry are governed by the Railway Labor Act (RLA), which grants the National Mediation Board (NMB) with certain functions with respect to disputes between airlines and labor unions, including those relating to union representation and CBAs. The following table shows our domestic airline employee groups that are represented by unions: Union Class or Craft Employees (1) Contract Amendable Date Mainline: Allied Pilots Association (APA) Pilots 14,970 2027 Association of Professional Flight Attendants (APFA) Flight Attendants 26,400 2029 Airline Customer Service Employee Association – Communications Workers of America and International Brotherhood of Teamsters (CWA-IBT) Passenger Service 13,030 2029 Transport Workers Union and International Association of Machinists & Aerospace Workers (TWU-IAM Association) Mechanics and Related 13,040 2027 TWU-IAM Association Fleet Service 19,460 2027 TWU-IAM Association Stock Clerks 2,090 2027 TWU-IAM Association Flight Simulator Engineers 150 2030 TWU-IAM Association Maintenance Control Technicians 190 2027 TWU-IAM Association Maintenance Training Instructors 100 2027 Professional Airline Flight Control Association (PAFCA) Dispatchers 570 2025 Transport Workers Union (TWU) Flight Crew Training Instructors 350 2031 13 Table of Contents Union Class or Craft Employees (1) Contract Amendable Date Envoy: Air Line Pilots Associations (ALPA) Pilots 2,330 2029 Association of Flight Attendants-CWA (AFA) Flight Attendants 2,350 2026 TWU Ground School Instructors 10 2027 TWU Mechanics and Related 1,370 2027 TWU Stock Clerks 140 2027 TWU Simulator Instructors 20 2026 TWU Fleet Service 4,300 2026 TWU Dispatchers 90 2025 Communications Workers of America (CWA) Passenger Service 7,730 2026 Piedmont: ALPA Pilots 840 2029 AFA Flight Attendants 400 2026 International Brotherhood of Teamsters (IBT) Mechanics and Related 540 2026 IBT Stock Clerks 70 2026 CWA Fleet and Passenger Service 6,750 2023 IBT Dispatchers 40 2029 PSA: ALPA Pilots 1,930 2028 AFA Flight Attendants 1,370 2023 International Association of Machinists & Aerospace Workers (IAM) Mechanics and Related 780 2027 IAM Stock Clerks 160 N/A (2) TWU Flight Crew Training Instructors 50 N/A (2) TWU Dispatchers 60 2027 (1)Represents approximate number of active employees as of December 31, 2025. (2)PSA stock clerks and certain PSA flight crew training instructors unionized in 2025 and are in active negotiations for their first CBA. The CBA covering our mainline dispatchers is now amendable and we are engaged in negotiations. In January 2026, our mainline flight crew training instructors ratified a five-year agreement which is now amendable in 2031. Among our wholly-owned regional subsidiaries, Envoy dispatchers, Piedmont fleet and passenger service and PSA flight attendants have CBAs that are now amendable and we are engaged in negotiations. For more discussion, see Part I, Item 1A. Risk Factors – “Union disputes, employee strikes and other labor-related disruptions may adversely affect our operations and financial performance.” Customers We fly to over 350 destinations in the United States and internationally, and we are committed to providing our customers with a world-class travel experience. We continued to rigorously measure and track customer satisfaction through passenger surveys in 2025, efforts that led to further improvements in the services we provide and our customer experience. In 2025, we appointed a Chief Customer Officer to lead a newly created Customer Experience organization, which drives the strategy and coordinates the implementation of initiatives that enhance our customers’ journeys. We continue to invest in the customer experience and our premium products and services, and in 2025, we advanced this strategy through the following: •introduced the new premium Flagship Suite® on our Boeing 787-9s and Airbus A321XLRs and announced plans to expand this product to our Boeing 777 fleet; 14 Table of Contents •enhanced our inflight services with new food and beverage offerings as well as upgraded amenity kits; •redesigned the American Airlines mobile application to better support customers with new features and a more intuitive, modern design; •announced complimentary high-speed Wi-Fi sponsored by AT&T, exclusive to our AAdvantage members, which became effective in January 2026 on our narrowbody and dual-class regional fleets and will be available on nearly every American Airlines flight by spring 2026; •opened the first Flagship® lounge in Philadelphia and debuted Provisions by Admirals ClubSM lounge in Charlotte, a first-of-its-kind space created for travelers on the go. We also announced plans to expand our premium lounge footprint with new Flagship® lounges in Miami and Charlotte and upgrades to our existing Admirals Club® lounges in Washington D.C, Miami and Charlotte; and •established new partnerships, including with FIFA, U.S. Soccer and PGA of America, enabling American to connect customers to major events, including the FIFA World Cup 26TM. Environmental Sustainability Our long-term goal is to reduce our GHG emissions to reach net-zero emissions by 2050. However, aviation remains a “hard to abate” industry, and it will require significant action and investments by governments, manufacturers and other stakeholders to achieve our goals. We are committed to working to improve the efficiency of our own operations, primarily through fleet renewal, and to partnering with other businesses, policymakers, scientists and innovators to scale alternative energy sources and propulsion systems with the potential to reduce our industry’s GHG emissions. In 2025, we advanced a range of innovative initiatives aimed at reducing those emissions and minimizing environmental impacts across our operations. •Fleet renewal. We continue to make our mainline fleet more efficient. In 2025, we took delivery of 40 latest-generation aircraft, including 23 Boeing 737-8 MAX, 11 Boeing 787-9, five Airbus A321XLR and one Airbus A321neo. We believe that the A321XLR, a longer-range version of the A321neo, will enable us to serve transatlantic markets using an estimated 10% less jet fuel per seat than current widebody aircraft due to latest-generation engines, improved aerodynamics and lighter weight materials. Since 2019, our fleet renewal and optimization efforts have led to an estimated 6.7% improvement in mainline fuel efficiency. •Fuel efficiency. We achieved fuel savings through initiatives including flight optimization systems and programs to reduce on-the-ground fuel use. Our flight management system, which enables pilots to see real-time weather and other information in flight to inform adjustments to their flight paths, saved approximately 12.3 million gallons of fuel in 2025 and nearly 44 million gallons since we introduced it in late 2020. In 2025, we also began the reconfiguration of our Boeing 777-300ER fleet to add seats, which will result in a nearly 8% improvement in fuel efficiency per seat when the project is complete. Also in 2025, we significantly increased our use of single-engine taxi operations, saving 1.3 million gallons of jet fuel, a 25% increase over 2024. •Next-generation aircraft. American has invested in ZeroAvia to help advance the development of its hydrogen fuel cell-powered electric aircraft engines. ZeroAvia’s technology uses green hydrogen to produce electricity through a catalytic chemical reaction, which then powers the motors of the aircraft. ZeroAvia is working to retrofit and linefit its powertrains to existing FAA-certified fixed-wing aircraft, a strategy aimed at simplifying the regulatory process and reducing time to market. American has also entered into a conditional purchase agreement for up to 100 engines, which we hope will ultimately allow us to retrofit and power aircraft like the Bombardier CRJ700 regional jet with ZeroAvia’s hydrogen-electric powertrain. In addition, we are an investor in and customer of Vertical Aerospace, thereby supporting the development of an emissions-free electric vertical takeoff and landing aircraft for passenger transportation. In 2025, Vertical Aerospace advanced its piloted prototype program from hover testing to high-speed wingborne flight. 15 Table of Contents •Sustainable aviation fuel (SAF). In 2025, we evaluated opportunities to maximize our contribution to accelerating the growth of the nascent SAF market. As a result, American and Alaska Airlines, in partnership with Breakthrough Energy Ventures and other oneworld carriers, led the launch of a new investment fund that seeks to accelerate the global development of long-term, lower emissions aviation fuel solutions designed to be cost effective and scalable. We also pursued the purchase of SAF in the voluntary market and in 2025, took delivery of more than 6.8 million gallons of SAF, which represents a small fraction of our overall fuel consumption but more than twice the volume of SAF we purchased voluntarily in 2024. Aircraft Fuel Our operations and financial results are materially affected by the availability and price of aircraft fuel, which represents one of the largest single cost items in our business. Based on our 2026 forecasted mainline and regional fuel consumption, we estimate that a one cent per gallon increase in the price of aircraft fuel would increase our 2026 annual fuel expense by approximately $50 million. The following table shows annual aircraft fuel consumption and costs, including taxes, for our mainline and regional operations for 2025 and 2024 (gallons and aircraft fuel expense in millions). Year Gallons Average Price per Gallon Aircraft Fuel Expense Percent of Total Operating Expenses 2025 4,488 $2.39 $10,718 20% 2024 4,391 $2.60 $11,418 22% As of December 31, 2025, we did not have any fuel hedging contracts outstanding to hedge our fuel consumption. Our current policy is not to enter into transactions to hedge our fuel consumption, although we review this policy from time to time based on market conditions and other factors. As such, and assuming we do not enter into any future transactions to hedge our fuel consumption, we will continue to be fully exposed to fluctuations in aircraft fuel prices. Aircraft fuel prices have in the past, and may in the future, experience substantial volatility. We cannot predict the future availability, price volatility or cost of aircraft fuel. For more discussion, see Part I, Item 1A. Risk Factors – “Our business is very dependent on the price and availability of aircraft fuel. Continued periods of high volatility in fuel costs, increased fuel prices or significant disruptions in the supply of aircraft fuel could have a significant negative impact on consumer demand, our operating results and liquidity.” Seasonality and Other Factors Due to the greater demand for air travel during summer months, revenues in the airline industry exhibit seasonal patterns based on peak travel periods. General economic conditions, fears of terrorism or war, fare initiatives, fluctuations in fuel prices, labor actions, weather, natural disasters, outbreaks of disease, geopolitical factors and other factors could impact this seasonal pattern. Therefore, our quarterly results of operations are not necessarily indicative of operating results for the entire year, and historical operating results in a quarterly or annual period are not necessarily indicative of future operating results. Domestic and Global Regulatory Landscape General Airlines are subject to extensive domestic and international regulatory requirements. Domestically, the U.S. Department of Transportation (DOT) and the FAA exercise significant regulatory authority over air carriers. The DOT, among other things, oversees and regulates domestic and international codeshare agreements, international route authorities, competition and consumer protection matters including accessibility, the display and sharing of ancillary fee information and refund practices. The Antitrust Division of the Department of Justice, along with the DOT in certain instances, has jurisdiction over airline antitrust matters. The FAA similarly exercises safety oversight and regulates most operational matters of our business, including how we operate and maintain our aircraft. FAA requirements cover, among other things, required technology and necessary onboard equipment; systems, procedures and training necessary to ensure the continuous airworthiness of our aircraft; safety measures and equipment; crew scheduling limitations and experience requirements; and many other technical aspects of airline operations. Additionally, our pilots and other employees are subject to rigorous certification standards, and our pilots and other crew members must adhere to flight time and rest requirements. 16 Table of Contents The FAA also controls the national airspace system, including operational rules and fees for air traffic control (ATC) services. The efficiency, reliability and capacity of the ATC network have a significant impact on our costs and on the timeliness of our operations. The U.S. Postal Service has jurisdiction over certain aspects of the transportation of mail and related services. Airport Access and Operations Domestically, any U.S. airline authorized by the DOT is generally free to operate scheduled passenger service between any two points within the U.S. and its territories, with the exception of certain airports that require landing and take-off rights and authorizations (slots) and other facilities, and certain airports that impose geographic limitations on operations or curtail operations based on the time of day. Operations at three major domestic airports we serve (John F. Kennedy International Airport (JFK) and LaGuardia Airport (LGA) in New York City, and Ronald Reagan Washington National Airport (DCA) near Washington, D.C.) and many foreign airports we serve (including LHR) are regulated by governmental entities through allocations of slots or similar regulatory mechanisms that limit the rights of carriers to conduct operations at those airports. Each slot represents the authorization to land at and take off from the particular airport during a specified time period. In addition to slot restrictions, operations at DCA and LGA are also limited based on a so-called “perimeter rule” which generally limits the stage length of the flights that can be operated from those airports to 1,250 and 1,500 miles, respectively. Generally, our ability to retain slots is conditioned on the continued use of such slots, and in the absence of use, the slots are subject to forfeiture. In certain circumstances, such as during the COVID-19 pandemic, regulators may issue slot waivers which temporarily suspend or amend slot usage requirements, and we have used slot waivers at times to reduce flying levels during periods of reduced demand for travel. Moreover, the FAA has issued slot waivers for New York City area airports as a result of operational challenges arising from ATC staffing shortages; those waivers are now set to expire in October 2026. We cannot guarantee that such waivers will be made available to us, or that upon expiration or cancellation of such waivers, it will be economical for us to resume prior levels of flying to destinations where we have operated a reduced service. If we are forced to surrender slots or other rights, we may be unable to provide our desired level of service to or from certain destinations in the future. For more discussion, see Part I, Item 1A. Risk Factors – “If we are unable to obtain and maintain adequate facilities and infrastructure throughout our system and, at some airports, adequate slots, we may be unable to operate our existing flight schedule and to expand or change our route network in the future, which may have a material adverse impact on our operations.” Our ability to provide service can also be impaired at airports where the airport gates and other facilities are currently inadequate to accommodate all of the service that we would like to provide, or where we have no access to gates at all. Existing law also permits domestic local airport authorities to implement procedures and impose restrictions designed to abate noise, provided such procedures and restrictions do not unreasonably interfere with interstate or foreign commerce or the national transportation system. In some instances, these restrictions have caused curtailments in service or increases in operating costs. Airline Fares, Taxes and User Fees Airlines are permitted to establish their own domestic fares without governmental regulation. The DOT maintains authority over certain international fares, rates and charges, but only applies this authority on a limited basis. In addition, international fares, rates and charges are sometimes subject to the jurisdiction of the governments of the foreign countries which we serve. Airlines are obligated to collect a federal excise tax, commonly referred to as the “ticket tax,” on domestic and international air transportation, and to collect other taxes and charge other fees, such as foreign taxes, security fees and passenger facility charges. Although these taxes and fees are not our operating expenses, they represent an additional cost to our customers. These taxes and fees are subject to increase from time to time. DOT Passenger Protection Rules The DOT regulates airline interactions with passengers through the ticketing process, at the airport and onboard the aircraft. Among other things, these regulations govern how our fares are displayed online, required customer disclosures, access by disabled passengers, handling of long onboard flight delays and reporting of mishandled bags. On September 4, 2025, the U.S. Government released its Unified Agenda of Regulatory and Deregulatory Actions, outlining planned priorities, timelines and policy directions across federal agencies. The agenda signals DOT’s intent to roll back existing regulations, including the refund rule, ancillary fee rule, compensation rule, and wheelchair rule. DOT 17 Table of Contents has already begun taking action, such as rescinding an Advance Notice of Proposed Rulemaking titled “Airline Passenger Rights,” which sought comments on requiring airlines to provide cash compensation, free rebooking, meal coverage and overnight lodging with related transportation when disruptions are airline-caused. International International air transportation is subject to extensive government regulation, including aviation agreements between the U.S. and other countries or governmental authorities, such as the EU. Moreover, our alliances with international carriers may be subject to the jurisdiction and regulations of various foreign agencies. The U.S. Government has negotiated “open skies” agreements with more than 130 trading partners, which allow unrestricted route authority access between the U.S. and the foreign markets. In addition, foreign countries impose passenger protection rules, which are analogous to, and often meet or exceed the requirements of, the DOT passenger protection rules discussed above. In cases where these foreign requirements exceed the DOT rules, we may bear additional burdens and liabilities. Further, various foreign airport authorities impose slot, noise and curfew restrictions at their local airports. Security All aspects of civil aviation and border security in the U.S. affecting U.S. carriers are controlled or regulated by the federal government through the Transportation Security Administration (TSA) and the U.S. Customs and Border Protection (CBP). The TSA is responsible for the security of the nation’s transportation systems. The TSA’s requirements for aviation security include, among other things, screening of passengers, baggage, cargo, mail, employees and vendors; carriage of federal air marshals at no charge; and continuous background checks of all employees and vendor employees with access to secure areas of airports. Funding for the TSA is provided by a combination of air carrier fees, passenger fees and taxpayer funds. The CBP is responsible for securing the nation’s borders by combining customs, immigration and agricultural protection. The CBP regulatory requirements include the advanced transmission of reservation records, passport and cargo data to facilitate lawful travel and trade into the U.S. Funding for a portion of CBP operations is provided by a combination of fees collected by airlines. Our international service further requires us to comply with host government civil aviation security regimes and foreign border control authorities. In addition to meeting TSA and CBP regulatory requirements, we support programs that enhance security, compliance and operational efficiency while improving the passenger experience. These initiatives include TSA’s Touchless Identity Solution, which enables biometric identity verification at TSA security checkpoints, and CBP’s Enhanced Passenger Processing program, which uses facial recognition to expedite border clearance. We also participate in TSA’s One Stop Security pilot program to streamline security for connecting passengers and CBP’s International Remote Baggage Screening program, which facilitates pre-clearance of baggage for arriving international travelers. Environmental Matters Environmental Regulation The airline industry is subject to various environmental laws and regulations in the U.S. and other countries. U.S. federal laws with a particular effect on our operations include the Airport Noise and Capacity Act of 1990, the Clean Air Act, the Resource Conservation and Recovery Act, the Clean Water Act, the Safe Drinking Water Act and the Comprehensive Environmental Response, Compensation and Liability Act. The U.S. Environmental Protection Agency (EPA) and other federal agencies promulgate regulations that affect our operations. In light of recent announcements and actions by the U.S. Government to reconsider air- and climate-related regulations and policies, the impact of regulatory changes has become increasingly difficult to predict. Additionally, various states have been delegated certain authorities under these aforementioned federal statutes, and many state and local governments have adopted environmental laws and regulations that mirror or are more stringent than federal requirements. Revised underground storage tank regulations issued by the EPA in 2015 have affected certain airport fuel hydrant systems, with modifications of those systems needed to comply with the revised regulations. As part of EPA and state regulations of storm water management, several U.S. airport authorities are trying to limit permitted discharges of deicing fluid into the environment, which can include requiring airlines to help build or reconfigure airport deicing facilities. Additionally, compliance with updated federal and state regulations governing firefighting foams require modifications to the fire suppression systems we operate, as well as those maintained by airports. On November 23, 2022, the EPA also published the final rule for particulate matter emission standards and test procedures for civil aircraft engines, which took 18 Table of Contents effect on December 23, 2022. These or similar regulations could result in increased compliance costs, but at this time we do not expect these costs to be material. Environmental laws include those related to responsibility for potential soil and groundwater contamination. We are conducting ongoing investigation and remediation activities to address environmental conditions at several sites that may have been impacted by our historic operations, including airports and maintenance bases. We anticipate that the ongoing costs of those activities will not materially affect our operations. We employ an environmental management system that provides a systematic approach for monitoring changes to and compliance with environmental regulations, and for managing a broad range of environmental issues, including air emissions, hazardous waste, underground tanks, and aircraft water quality. Global and Domestic Regulation Related to Climate Change Climate change-related regulatory activity and developments may adversely affect our business and financial results by requiring us to adapt to rapidly evolving domestic and international regulations and to achieve GHG emission reductions before cost-effective technologies are available. For example, such regulations may require us or our suppliers to make capital investments to purchase specific equipment or technologies, purchase SAF, pay taxes and fees or otherwise incur additional costs related to our emissions. These trends may also increase our operating costs, including fuel costs. The Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) CORSIA is an international, market-based emissions reduction program adopted by the International Civil Aviation Organization (ICAO) in 2016 and is intended to limit emissions in the international aviation sector from 2021 until 2035 through the purchase of eligible carbon offset credits or the use of eligible renewable fuels. For each year from 2021 through 2032, CORSIA requires airlines to compensate for the growth of carbon dioxide (CO2) emissions from the aviation sector, relative to a predetermined ICAO baseline. ICAO originally defined the baseline as the average emissions from covered flights in 2019 and 2020. However, due to the effect of the COVID-19 pandemic on air travel, in June 2020, ICAO removed 2020 from the baseline calculation for the CORSIA pilot phase (2021-2023). In October 2022, ICAO member countries agreed that 85% of 2019 emissions would be used as the baseline for the remainder of CORSIA’s term (2024-2035). The CORSIA program is being implemented in three phases: a pilot phase that ran from 2021 through 2023, followed by a first phase covering 2024 through 2026 and a second phase beginning in 2027 through 2035. ICAO member countries are expected to enact legislation to implement CORSIA. In December 2025, ICAO confirmed that governments participating in CORSIA are expected to inform airlines of their carbon emissions offsetting requirements for the first year (2024) of CORSIA’s first phase in the near future. Our future costs related to CORSIA compliance are uncertain due to a variety of factors, including the status of the U.S. Government’s implementation of CORSIA with respect to the obligations of aircraft operators to purchase carbon offsets, uncertainty in the growth of covered CO2 emissions, the supply and price of CORSIA-eligible carbon offset credits and the development of the market for eligible renewable fuels. European GHG Emissions Regulations On May 16, 2023, revisions to the EU Emissions Trading System (EU ETS) were published in the Official Journal of the EU. Under these revisions, the allocation of free emissions allowances to aircraft operators was phased out by the end of 2025. Also, by July 2026, the EC will have to undertake a review to determine whether CORSIA sufficiently delivers on the goals of the Paris Agreement. Depending on the outcome of that review, the EU may expand the scope of the EU ETS, which is currently limited to flights within the European Economic Area (EEA), to include any flight departing the EEA. Should the EU expand the EU ETS scope, there could be serious repercussions for our business and the broader industry, and our costs to comply with the EU ETS would likely be significant. The UK and Switzerland have similar emissions trading schemes that often align with the EU ETS; our compliance costs would further increase if both countries followed the EU in extending the scope of their regulation of GHG emissions from aviation. The EU’s ReFuelEU Aviation initiative, which creates a SAF blending mandate for aviation fuel suppliers, took effect January 1, 2025. This regulation requires fuel suppliers to blend minimum shares of SAF with petroleum jet fuel in the fuel delivered to aircraft operators at EU airports. The minimum requirements are 2% from 2025, 6% from 2030, 20% from 2035, 34% from 2040, 42% from 2045 and 70% from 2050. A specific proportion of the fuel mix (an average of 1.2% in 19 Table of Contents 2030-2031, an average of 2% in 2032-2034, a minimum of 5% from 2035 and progressively reaching a minimum of 35% from 2050) must comprise synthetic fuels such as e-kerosene. The UK also adopted a SAF mandate for aviation fuel suppliers, starting January 1, 2025, with minimum requirements that increase linearly from 2% in 2025, to 10% in 2030 and to 22% in 2040. The UK SAF mandate policy includes separate targets for e-kerosene (referred to under the obligation as power-to-liquid fuels), which start from 2028, and a cap, starting in 2027, on the amount of SAF made from hydrotreated fats and oils that fuel suppliers may use to reach the annual blending targets. Nearly all SAF produced today is made from hydrotreated fats and oils, and it is uncertain whether eligible SAF will be available to meet this requirement. While we expect these requirements to increase our fuel costs, it remains uncertain by how much costs will rise, whether those costs can be passed on to customers, and, assuming they can, whether higher prices will affect customer demand. There is also uncertainty regarding how the EU and UK may implement the SAF mandates, including, the extent to which the relevant governments will change their existing policies or adopt new policies such as flexibility mechanisms for suppliers (e.g., book and claim) and revenue certainty programs for SAF producers. Other countries have adopted, or are considering adopting, similar SAF blending mandates. U.S. Emissions Standards for Aircraft Engines In January 2021, the EPA adopted GHG emission standards for new aircraft engines, aligning with the 2017 ICAO aircraft engine GHG emission standards. Similar to the ICAO standards, the EPA’s standards do not apply retroactively to engines on in-service aircraft. Pursuant to the Clean Air Act, the FAA issued a final rule in February 2024 to implement these standards, introducing new fuel efficiency certification regulations. These regulations, which took effect in April 2024, apply to airplanes manufactured after January 1, 2028, as well as to uncertified large business and commercial jet aircraft. Given announcements and actions by the U.S. Government to reconsider air- and climate-related regulations and policies, the future and impact of these new requirements remain uncertain. For more information on our approach to climate change, see our 2024 Sustainability Report on our website www.aa.com available under “Sustainability.” None of the information or contents under our “Sustainability” page, 2024 Sustainability Report, or our website are incorporated into this Annual Report on Form 10-K. Impact of Regulatory Requirements on Our Business Regulatory requirements, including but not limited to those discussed above, affect operations and increase operating costs for the airline industry, including our airline subsidiaries, and future regulatory developments may continue to do the same. For additional information, see Part I, Item 1A. Risk Factors – “Evolving data privacy requirements (in particular, compliance with applicable federal, state and foreign laws relating to handling of personal information about individuals) could increase our costs, and any significant data privacy incident could disrupt our operations, harm our reputation, expose us to legal risks and otherwise materially adversely affect our business, results of operations and financial condition,” “If we are unable to obtain and maintain adequate facilities and infrastructure throughout our system and, at some airports, adequate slots, we may be unable to operate our existing flight schedule and to expand or change our route network in the future, which may have a material adverse impact on our operations,” “Our business is subject to extensive government regulation, which may result in increases in our costs, disruptions to our operations, limits on our operating flexibility, reductions in the demand for air travel, and competitive disadvantages,” “The airline industry is heavily taxed,” “We are subject to many forms of environmental and noise regulation and may incur substantial costs as a result,” and “We are subject to risks associated with climate change, including increased regulation of our GHG emissions, changing consumer preferences and the potential for increased impacts of severe weather events on our operations and infrastructure.” Available Information Use of Websites to Disclose Information Our website is located at www.aa.com.

BUSINESS Overview American Airlines Group Inc. (AAG), a Delaware corporation, is a holding company and its principal, wholly-owned subsidiaries are American Airlines, Inc. (American), Envoy Aviation Group Inc., PSA Airlines, Inc. (PSA) and Piedmont Airlines, Inc. (Piedmont). AAG was formed in 1982, under the name AMR Corporation (AMR), as the parent company of American, which was founded in 1934, with roots tracing back to an air mail carrier in the Midwestern United States in 1926. AAG’s and American’s principal executive offices are located at 1 Skyview Drive, Fort Worth, Texas 76155 and their telephone number is 682-278-9000. Airline Operations Together with our wholly-owned regional airline subsidiaries and third-party regional carriers operating as American Eagle, our primary business activity is the operation of a major network air carrier, providing scheduled air transportation for passengers and cargo through our hubs in Charlotte, Chicago, Dallas/Fort Worth, Los Angeles, Miami, New York, Philadelphia, Phoenix and Washington, D.C. and partner gateways, including in London, Doha, Madrid, Seattle/Tacoma, Sydney and Tokyo (among others). We provide service to over 350 destinations around the world, and in 2025, approximately 224 million passengers boarded our flights. In 2025, we launched more than 60 new routes, including to trans-Atlantic destinations such as Spain, Italy and Greece. We also announced over 20 new routes for customers to explore in 2026, including our first trans-Atlantic route to be flown by the Airbus A321XLR from New York to Edinburgh, Scotland. As of December 31, 2025, we operated 1,013 mainline aircraft supported by our wholly-owned regional airline subsidiaries and third-party regional carriers, which together operated an additional 567 regional aircraft. See Part I, Item 2. Properties for further discussion of our mainline and regional aircraft and “Regional” below for further discussion of our regional operations. American is a founding member of the oneworld® Alliance, which brings together a global network of 15 world-class member airlines and their affiliates, working together to provide a superior and seamless travel experience. See “Distribution and Marketing Agreements” below for further discussion on the oneworld Alliance and other agreements with domestic and international airlines. See Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations – “2025 Financial Overview,” “AAG’s Results of Operations” and “American’s Results of Operations” for further discussion of AAG’s and American’s operating results and operating performance. Also, see Note 1(m) to each of AAG’s and American’s Consolidated Financial Statements in Part II, Items 8A and 8B, respectively, for passenger revenue by geographic region and Note 13 to AAG’s Consolidated Financial Statements in Part II, Item 8A and Note 12 to American’s Consolidated Financial Statements in Part II, Item 8B for segment disclosures. Regional Our regional carriers provide scheduled air transportation under the brand name “American Eagle.” The American Eagle carriers include our wholly-owned regional carriers Envoy Air Inc. (Envoy), PSA and Piedmont, as well as third-party regional carriers including Republic Airways Inc. (Republic) and SkyWest Airlines, Inc. (SkyWest). Our regional carriers are an integral component of our operating network. We rely heavily on regional carriers to serve small markets and also to drive connecting traffic to our hubs from markets that are not economical for us to serve with larger mainline aircraft. In addition, regional carriers offer complementary service in many of our mainline markets. All American Eagle carriers use logos, service marks, aircraft paint schemes and uniforms similar to those of our mainline operations. In 2025, 57 million passengers boarded our regional flights, approximately 42% of whom connected to or from our mainline flights. Our regional carrier arrangements are principally in the form of capacity purchase agreements with our third-party regional partners and similar arrangements with our wholly-owned affiliates which provide that all revenues, including passenger, in-flight, ancillary, mail and freight revenues, go to us. We control marketing, scheduling, ticketing, pricing and seat inventories. In return, we agree to pay predetermined fees to these airlines for operating an agreed-upon number of aircraft, without regard to the number of passengers on board. In addition, these agreements provide that we either reimburse or pay 100% of certain variable costs, such as airport landing fees, fuel and passenger liability insurance. 8 Table of Contents Cargo Our cargo division provides a wide range of freight and mail services, with facilities and interline connections available across the globe. In 2025, we served over 20,000 unique origin and destination pairs, transporting approximately 1.0 billion pounds of time-sensitive freight and mail throughout our network. We continue to focus on enhancements that enable us to better serve our customers, including moving to a new facility at London Heathrow Airport (LHR) to support further growth in this key market and expanding our digital offerings, which provide greater efficiency, increased accuracy, 24/7 access to search schedules, and the ability for our customers to check availability, retrieve rates and make bookings. Distribution and Marketing Agreements Passengers can purchase tickets for travel on American and American Eagle through several distribution channels, including our website (www.aa.com), our mobile app and our reservations centers, and through third-party distribution channels, including conventional travel agents, travel management companies and online travel agents (OTAs) (e.g., Expedia, including its booking sites Orbitz and Travelocity, and Booking Holdings, including its booking sites Kayak and Priceline). Additionally, American utilizes new distribution technologies such as IATA New Distribution Capability (NDC) technology, which we distribute our content to third parties through aggregators (e.g., Amadeus, Sabre, Travelport and Travelfusion) or through direct connections. NDC technology provides customers access to enhanced content and functionality, providing a simplified booking experience, and enabling us to provide more relevant, tailored offers to customers. To remain competitive, we will need to successfully manage our distribution costs and rights, increase our distribution flexibility and improve the functionality of our distribution channels, while maintaining an industry-competitive cost structure. For more discussion, see Part I, Item 1A. Risk Factors – “We rely on third-party distribution channels and must effectively manage the costs, rights and functionality of these channels.” Member of oneworld Alliance American is a founding member of the oneworld Alliance, which currently includes Alaska Airlines, British Airways, Cathay Pacific, Fiji Airways, Finnair, Iberia, Japan Airlines, Malaysia Airlines, Oman Air, Qantas Airways, Qatar Airways, Royal Air Maroc, Royal Jordanian Airlines and SriLankan Airlines. Hawaiian Airlines is expected to join the oneworld Alliance in 2026. The oneworld Alliance links the networks of member carriers and their respective affiliates to enhance customer service and provide smooth connections to the destinations served by the alliance, including linking member carriers’ loyalty programs and providing reciprocal access to the carriers’ airport lounge facilities. Joint Business Agreements and Other Cooperation Agreements American has established a transatlantic joint business with British Airways, Aer Lingus, Iberia and Finnair, a transpacific joint business with Japan Airlines and a joint business covering Australia and New Zealand with Qantas Airways. Joint business agreements enable the carriers involved to cooperate on flights between particular destinations and allow pooling and sharing of certain revenues and costs, enhanced loyalty program reciprocity and cooperation in other areas. Joint business agreements have become a common approach among major carriers to address key regulatory restrictions typically applicable to international airline service, including limitations on the foreign ownership of airlines and national laws prohibiting foreign airlines from carrying passengers beyond specific gateway cities. We also have established strategic alliances with Alaska Airlines and Qatar Airways that deliver to our customers an improved network offering and enhanced loyalty program reciprocity, among other benefits. In July 2010, in connection with a regulatory review related to our transatlantic joint business, we provided certain commitments to the European Commission (EC) regarding, among other things, the availability of take-off and landing slots at LHR or London Gatwick Airport (LGW). The commitments accepted by the EC were binding for 10 years. In anticipation of both the exit of the United Kingdom (UK) from the European Union (EU), commonly referred to as Brexit, and the expiration of the EC commitments in July 2020, the United Kingdom Competition and Markets Authority (CMA), in October 2018, opened an investigation into the transatlantic joint business. In September 2020 and April 2022, the CMA adopted interim measures that extend the EC commitments until March 2026 in light of the uncertainty and other impacts resulting from the COVID-19 pandemic. In August 2025, the CMA accepted binding commitments and closed the case. The commitments will replace the prior interim measures. The foregoing arrangements are important aspects of our international network, and we are dependent on the performance and continued cooperation of the other airlines party to those arrangements. 9 Table of Contents Marketing Relationships To improve access to each other’s markets, various U.S. and foreign air carriers, including American, have established marketing agreements with other airlines. These marketing agreements vary in scope and are intended to provide enhanced customer choice by means of an expanded network with loyalty program participation, but do not involve the same level of cooperation as our joint businesses or strategic alliances. As of December 31, 2025, in addition to the relationships described above, American had codeshare, marketing and/or loyalty program relationships with Air Tahiti Nui, China Southern Airlines Company Limited (China Southern Airlines), Etihad Airways, GOL Linhas Aéreas Inteligentes S.A. (GOL), Gulf Air, Hawaiian Airlines, IndiGo, JetSMART, Jetstar, Jetstar Japan, Korean Air Lines, Philippine Airlines, Porter Airlines and Vueling Airlines. AAdvantage® Program Our AAdvantage program was established to enhance passenger loyalty by offering benefits and rewards to travelers for their continued patronage with American and our partners. AAdvantage members enjoy exclusive benefits and earn AAdvantage mileage credits (miles) for flying on eligible tickets on American, American Eagle, any oneworld Alliance airline or other partner airlines. Along with AAdvantage miles, members also earn Loyalty Points, which unlock AAdvantage status and rewards for our AAdvantage members. For every dollar spent by flying on an eligible American ticket, members earn mileage credits, and AAdvantage Gold®, AAdvantage Platinum®, AAdvantage Platinum Pro® and AAdvantage Executive Platinum® status holders earn additional bonus mileage credits of 40%, 60%, 80% and 120%, respectively. Members also earn mileage credits and Loyalty Points by using the services of more than 1,000 non-flight partners, such as our co-branded credit cards, certain hotel, car rental and cruise companies and shopping and dining partners. The AAdvantage program in general, and our co-branded credit card programs in particular, are material assets of our business and have become increasingly important to our company over time. Starting in 2026, Citibank N.A. (Citi) became the exclusive issuer of the AAdvantage co-branded credit card portfolio in the U.S. Cash payments from co-branded credit card and other partners were $6.2 billion and $6.1 billion during 2025 and 2024, respectively. Cash remuneration in 2024 included a one-time cash payment related to the new co-branded credit card agreement announced in December 2024. In July 2025, we extended our agreement with Mastercard pursuant to a new 10‑year contract, under which Mastercard remains the exclusive payment network for our AAdvantage co‑branded credit cards. We will enhance our AAdvantage program using Mastercard’s payments infrastructure and analytics to deliver more personalized offers to AAdvantage members, optimize rewards and provide seamless, secure transactions. Mastercard’s technology will power real-time fraud detection and optimize payments from booking to in flight. Additionally, AAdvantage members will have new ways to redeem miles for Mastercard’s Priceless Experiences. Mileage credits can be redeemed for travel and upgraded experiences on American and participating airlines, access to our Admirals Club® and Flagship Lounges®, or for other non-flight awards, such as car rentals, hotel stays, cruises and retail goods from our program partners. Travel awards are available on all flights operated by American and, subject to capacity-controlled seating, on flights operated by our partners. A member’s mileage credits generally do not expire if that member has any type of qualifying activity at least once every 24 months or if the AAdvantage member is the primary holder of a co-branded credit card. AAdvantage members qualify for status over a 12-month period beginning on March 1 of each year by earning Loyalty Points. Status members can enjoy additional travel benefits of the AAdvantage program, including complimentary upgrades, checked bags, and Preferred and Main Cabin Extra seats, as well as priority check-in, security, boarding and baggage delivery when traveling on American, American Eagle, any oneworld Alliance airline or select partner airlines. In addition, AAdvantage members can unlock benefits, rewards and choices before, between and beyond the traditional status tiers with Loyalty Point Rewards. AAdvantage Business, our business loyalty program, rewards both eligible companies with AAdvantage miles and their travelers with additional Loyalty Points when booking business travel. In 2025, the AAdvantage program was recognized for Best Customer Service and Best Redemption Ability in the Americas and the Citi®/AAdvantage® Platinum Select® World Elite Mastercard® co-branded credit card was recognized as the Best Loyalty Credit Card in the Americas at the 2025 Freddie Awards. The Freddie Awards recognize the best travel loyalty programs across the world and are based on votes from travelers. Under our agreements with AAdvantage members and program partners, we reserve the right to change the terms of the AAdvantage program at any time and without notice. Program rules, partners, special offers, awards and requisite mileage levels for awards are subject to change. 10 Table of Contents During 2025, our members redeemed approximately 18 million awards, including travel redemptions for flights and upgrades on American, American Eagle and other air carriers, as well as redemption of car and hotel awards, club memberships and merchandise, among others. Approximately 9% of our 2025 total revenue passenger miles flown were from award travel. See Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations – “Critical Accounting Policies and Estimates” for more information on our loyalty program. Industry Competition Domestic The markets in which we operate are highly competitive. On most of our domestic nonstop routes, we face competing service from other domestic airlines, including major network airlines, low-cost carriers and ultra-low-cost carriers such as Alaska Airlines, Allegiant Air, Delta Air Lines, Frontier Airlines, Hawaiian Airlines, JetBlue Airways, Southwest Airlines, Spirit Airlines and United Airlines. Between cities that require a connection, where the major airlines compete via their respective hubs, competition is significant. In addition, we face competition on some of our connecting routes from airlines operating point-to-point service. We also compete with all-cargo and charter airlines and, particularly on shorter segments, ground and rail transportation. In general, beyond nonstop city pairs, carriers that have the greatest ability to seamlessly connect passengers to and from markets have a competitive advantage. In some cases, however, foreign governments limit U.S. air carriers’ rights to transport passengers beyond designated gateway cities in foreign countries. In order to improve access to domestic and foreign markets, we have arrangements with other airlines including through the oneworld Alliance, joint business agreements and other cooperation agreements and marketing relationships, as further discussed herein. On all of our routes, pricing decisions are affected, in large part, by the need to meet competition from other airlines. Price competition occurs on a market-by-market basis through price discounts, changes in pricing structures, fare matching, targeted promotions and loyalty program initiatives. Airlines typically use discounted fares and other promotions to stimulate traffic during normally weak travel periods, when they begin service to new cities, when they have excess capacity, to generate cash flow, to maximize revenue per available seat mile or to establish, increase or preserve market share. Most airlines will quickly match price reductions in a particular market, and we have often elected to match discounted or promotional fares initiated by other air carriers in certain markets in order to compete in those markets. In addition, we face pricing pressures from so-called ultra-low-cost carriers, such as Allegiant Air, Frontier Airlines and Spirit Airlines, which compete in many of the markets in which we operate. In addition to price competition, airlines compete for market share by increasing the size of their route system and the number of markets they serve. The American Eagle regional carriers increase the number of markets we serve by flying to smaller markets and providing connections at our hubs. Many of our competitors also own or have agreements with regional airlines that provide similar services at their hubs and other locations. We also compete on the basis of scheduling (frequency and flight times), availability of nonstop flights, on-time performance, type of equipment, cabin configuration, amenities provided to passengers, loyalty programs, the automation of travel agent reservation systems, onboard products, health and safety, sustainability initiatives and other services. International In addition to our extensive domestic service, we provide international service to Canada, Mexico, the Caribbean, Central and South America, Europe, Qatar, China, Japan, South Korea, India, Australia and New Zealand. In providing international air transportation, we compete with other U.S. airlines, foreign investor-owned airlines and foreign state-owned or state-affiliated airlines. Competition has also been increasing from low-cost airlines executing international long-haul expansion strategies, a trend we expect to continue, in particular with the introduction of long-range narrowbody aircraft. In order to increase our ability to compete in the market for international air transportation service, which is subject to extensive government regulation, U.S. and foreign carriers have entered into bilateral and multilateral marketing relationships, alliances, cooperation agreements and joint business agreements to exchange traffic among each other’s flights and route networks. See “Distribution and Marketing Agreements” above for further discussion. 11 Table of Contents Sustainability We aim to run a resilient, profitable enterprise that will thrive over the long term. Our strategy focuses on protecting the safety of team members and customers, attracting and developing top talent, providing a world-class travel experience and positioning American to compete in a low-carbon economy. Safety The safety of our customers and team members is a top priority. Our approach to safety is guided by our Federal Aviation Administration (FAA)-approved safety management systems (SMS), an organization-wide approach to identifying and managing risk. Each SMS is comprised of four components: Safety Policy, Safety Risk Management (SRM), Safety Assurance and Safety Promotion. Our Safety Policy sets safety objectives while striving to comply with applicable regulatory requirements and laws in the countries where we operate, and it establishes standards for acceptable operational behaviors. The SRM element of our SMS provides a decision-making process for identifying hazards and mitigating risk based on a thorough understanding of our systems and their operating environment. We employ SRM whenever there is a change to our processes, procedures or operations, such as the delivery of new aircraft. The Safety Assurance component specifies how we validate the effectiveness of risk controls and the performance of the SMS using data to conduct quality assurance and internal oversight. Lastly, the Safety Promotion component of our SMS includes communications and training to keep heightened awareness among team members to identify and report potential safety concerns. Our People The airline business is labor intensive, and our team members are critical to delivering for our customers. The operational complexity of our business requires a team of personnel trained and experienced in a variety of technical areas such as flight operations, ground operations, safety and maintenance, customer service and airline scheduling and planning. Fostering a culture where our team members feel supported to take care of our customers is critical to our success. To do this, we must continue to hire the best and the brightest, ensure that people from all backgrounds are aware of the opportunities that exist in aviation, and create a culture where everyone can reach their full potential and thrive. In 2025, mainline and regional salaries, wages and benefits were our largest expense and represented 38% of our total operating expenses. As of December 31, 2025, we had approximately 139,100 active full-time equivalent employees, approximately 86% of whom were represented by various labor unions responsible for negotiating the collective bargaining agreements (CBAs) governing their compensation and job duties, among other things. Talent Development We focus on providing our team members with the tools, training and resources they need to do their best work. We maintain a suite of programs aimed at helping our people develop the skills and experience they need to succeed in their roles and build rewarding, long-term careers within our company. Our Culture We seek to create a workplace where all perspectives and experiences are welcomed, valued and encouraged and where every individual, regardless of their national origin, religion, race, gender, sexual orientation or background, not only knows they belong, but that they can thrive at our company. Our goal is to make culture a competitive advantage so people will want to work with us, fly with us and invest in us. We believe in: •Hiring, engaging and retaining the best and the brightest talent for growth; •Delivering excellence in our operations to serve and expand our global markets; •Striving to have our teams build connections and trust with all who fly with us; and •Driving industry innovation to build competitive advantages. 12 Table of Contents Competitive Pay and Comprehensive Benefits We seek to offer competitive pay, comprehensive benefits and a wide variety of resources designed to support the physical, behavioral and financial well-being of our team members and their families, including medical coverage that is intended to be affordable and flexible along with healthcare navigation and support tools. Our internal recognition programs give team members and customers the opportunity to show their appreciation for a job well done, including through our Nonstop Thanks program whereby team members can award each other points for exceptional service or as an expression of gratitude. Recognition points earned through the Nonstop Thanks program can be redeemed for items in an online catalog. In 2025, our team members were recognized by customers, peers and company leaders approximately three million times. Additionally, approximately 1,000 peer nominations were submitted for the annual Circle of Excellence, the highest honor that we bestow upon our team members for their career achievements. Our future success depends in large part on our ability to attract, develop and retain highly qualified management, technical and other personnel. We may not be successful in attracting, developing or retaining key personnel or other highly qualified personnel. In addition, competition for skilled personnel has intensified and may continue to intensify if overall industry capacity continues to increase and/or we were to incur attrition at levels higher than we have historically. For more discussion, see Part I, Item 1A. Risk Factors – “The loss of key personnel whom we depend on to operate our business, or the inability to attract, develop and retain additional qualified personnel could adversely affect our business.” Labor Relations Labor relations in the air transportation industry are governed by the Railway Labor Act (RLA), which grants the National Mediation Board (NMB) with certain functions with respect to disputes between airlines and labor unions, including those relating to union representation and CBAs. The following table shows our domestic airline employee groups that are represented by unions: Union Class or Craft Employees (1) Contract Amendable Date Mainline: Allied Pilots Association (APA) Pilots 14,970 2027 Association of Professional Flight Attendants (APFA) Flight Attendants 26,400 2029 Airline Customer Service Employee Association – Communications Workers of America and International Brotherhood of Teamsters (CWA-IBT) Passenger Service 13,030 2029 Transport Workers Union and International Association of Machinists & Aerospace Workers (TWU-IAM Association) Mechanics and Related 13,040 2027 TWU-IAM Association Fleet Service 19,460 2027 TWU-IAM Association Stock Clerks 2,090 2027 TWU-IAM Association Flight Simulator Engineers 150 2030 TWU-IAM Association Maintenance Control Technicians 190 2027 TWU-IAM Association Maintenance Training Instructors 100 2027 Professional Airline Flight Control Association (PAFCA) Dispatchers 570 2025 Transport Workers Union (TWU) Flight Crew Training Instructors 350 2031 13 Table of Contents Union Class or Craft Employees (1) Contract Amendable Date Envoy: Air Line Pilots Associations (ALPA) Pilots 2,330 2029 Association of Flight Attendants-CWA (AFA) Flight Attendants 2,350 2026 TWU Ground School Instructors 10 2027 TWU Mechanics and Related 1,370 2027 TWU Stock Clerks 140 2027 TWU Simulator Instructors 20 2026 TWU Fleet Service 4,300 2026 TWU Dispatchers 90 2025 Communications Workers of America (CWA) Passenger Service 7,730 2026 Piedmont: ALPA Pilots 840 2029 AFA Flight Attendants 400 2026 International Brotherhood of Teamsters (IBT) Mechanics and Related 540 2026 IBT Stock Clerks 70 2026 CWA Fleet and Passenger Service 6,750 2023 IBT Dispatchers 40 2029 PSA: ALPA Pilots 1,930 2028 AFA Flight Attendants 1,370 2023 International Association of Machinists & Aerospace Workers (IAM) Mechanics and Related 780 2027 IAM Stock Clerks 160 N/A (2) TWU Flight Crew Training Instructors 50 N/A (2) TWU Dispatchers 60 2027 (1)Represents approximate number of active employees as of December 31, 2025. (2)PSA stock clerks and certain PSA flight crew training instructors unionized in 2025 and are in active negotiations for their first CBA. The CBA covering our mainline dispatchers is now amendable and we are engaged in negotiations. In January 2026, our mainline flight crew training instructors ratified a five-year agreement which is now amendable in 2031. Among our wholly-owned regional subsidiaries, Envoy dispatchers, Piedmont fleet and passenger service and PSA flight attendants have CBAs that are now amendable and we are engaged in negotiations. For more discussion, see Part I, Item 1A. Risk Factors – “Union disputes, employee strikes and other labor-related disruptions may adversely affect our operations and financial performance.” Customers We fly to over 350 destinations in the United States and internationally, and we are committed to providing our customers with a world-class travel experience. We continued to rigorously measure and track customer satisfaction through passenger surveys in 2025, efforts that led to further improvements in the services we provide and our customer experience. In 2025, we appointed a Chief Customer Officer to lead a newly created Customer Experience organization, which drives the strategy and coordinates the implementation of initiatives that enhance our customers’ journeys. We continue to invest in the customer experience and our premium products and services, and in 2025, we advanced this strategy through the following: •introduced the new premium Flagship Suite® on our Boeing 787-9s and Airbus A321XLRs and announced plans to expand this product to our Boeing 777 fleet; 14 Table of Contents •enhanced our inflight services with new food and beverage offerings as well as upgraded amenity kits; •redesigned the American Airlines mobile application to better support customers with new features and a more intuitive, modern design; •announced complimentary high-speed Wi-Fi sponsored by AT&T, exclusive to our AAdvantage members, which became effective in January 2026 on our narrowbody and dual-class regional fleets and will be available on nearly every American Airlines flight by spring 2026; •opened the first Flagship® lounge in Philadelphia and debuted Provisions by Admirals ClubSM lounge in Charlotte, a first-of-its-kind space created for travelers on the go. We also announced plans to expand our premium lounge footprint with new Flagship® lounges in Miami and Charlotte and upgrades to our existing Admirals Club® lounges in Washington D.C, Miami and Charlotte; and •established new partnerships, including with FIFA, U.S. Soccer and PGA of America, enabling American to connect customers to major events, including the FIFA World Cup 26TM. Environmental Sustainability Our long-term goal is to reduce our GHG emissions to reach net-zero emissions by 2050. However, aviation remains a “hard to abate” industry, and it will require significant action and investments by governments, manufacturers and other stakeholders to achieve our goals. We are committed to working to improve the efficiency of our own operations, primarily through fleet renewal, and to partnering with other businesses, policymakers, scientists and innovators to scale alternative energy sources and propulsion systems with the potential to reduce our industry’s GHG emissions. In 2025, we advanced a range of innovative initiatives aimed at reducing those emissions and minimizing environmental impacts across our operations. •Fleet renewal. We continue to make our mainline fleet more efficient. In 2025, we took delivery of 40 latest-generation aircraft, including 23 Boeing 737-8 MAX, 11 Boeing 787-9, five Airbus A321XLR and one Airbus A321neo. We believe that the A321XLR, a longer-range version of the A321neo, will enable us to serve transatlantic markets using an estimated 10% less jet fuel per seat than current widebody aircraft due to latest-generation engines, improved aerodynamics and lighter weight materials. Since 2019, our fleet renewal and optimization efforts have led to an estimated 6.7% improvement in mainline fuel efficiency. •Fuel efficiency. We achieved fuel savings through initiatives including flight optimization systems and programs to reduce on-the-ground fuel use. Our flight management system, which enables pilots to see real-time weather and other information in flight to inform adjustments to their flight paths, saved approximately 12.3 million gallons of fuel in 2025 and nearly 44 million gallons since we introduced it in late 2020. In 2025, we also began the reconfiguration of our Boeing 777-300ER fleet to add seats, which will result in a nearly 8% improvement in fuel efficiency per seat when the project is complete. Also in 2025, we significantly increased our use of single-engine taxi operations, saving 1.3 million gallons of jet fuel, a 25% increase over 2024. •Next-generation aircraft. American has invested in ZeroAvia to help advance the development of its hydrogen fuel cell-powered electric aircraft engines. ZeroAvia’s technology uses green hydrogen to produce electricity through a catalytic chemical reaction, which then powers the motors of the aircraft. ZeroAvia is working to retrofit and linefit its powertrains to existing FAA-certified fixed-wing aircraft, a strategy aimed at simplifying the regulatory process and reducing time to market. American has also entered into a conditional purchase agreement for up to 100 engines, which we hope will ultimately allow us to retrofit and power aircraft like the Bombardier CRJ700 regional jet with ZeroAvia’s hydrogen-electric powertrain. In addition, we are an investor in and customer of Vertical Aerospace, thereby supporting the development of an emissions-free electric vertical takeoff and landing aircraft for passenger transportation. In 2025, Vertical Aerospace advanced its piloted prototype program from hover testing to high-speed wingborne flight. 15 Table of Contents •Sustainable aviation fuel (SAF). In 2025, we evaluated opportunities to maximize our contribution to accelerating the growth of the nascent SAF market. As a result, American and Alaska Airlines, in partnership with Breakthrough Energy Ventures and other oneworld carriers, led the launch of a new investment fund that seeks to accelerate the global development of long-term, lower emissions aviation fuel solutions designed to be cost effective and scalable. We also pursued the purchase of SAF in the voluntary market and in 2025, took delivery of more than 6.8 million gallons of SAF, which represents a small fraction of our overall fuel consumption but more than twice the volume of SAF we purchased voluntarily in 2024. Aircraft Fuel Our operations and financial results are materially affected by the availability and price of aircraft fuel, which represents one of the largest single cost items in our business. Based on our 2026 forecasted mainline and regional fuel consumption, we estimate that a one cent per gallon increase in the price of aircraft fuel would increase our 2026 annual fuel expense by approximately $50 million. The following table shows annual aircraft fuel consumption and costs, including taxes, for our mainline and regional operations for 2025 and 2024 (gallons and aircraft fuel expense in millions). Year Gallons Average Price per Gallon Aircraft Fuel Expense Percent of Total Operating Expenses 2025 4,488 $2.39 $10,718 20% 2024 4,391 $2.60 $11,418 22% As of December 31, 2025, we did not have any fuel hedging contracts outstanding to hedge our fuel consumption. Our current policy is not to enter into transactions to hedge our fuel consumption, although we review this policy from time to time based on market conditions and other factors. As such, and assuming we do not enter into any future transactions to hedge our fuel consumption, we will continue to be fully exposed to fluctuations in aircraft fuel prices. Aircraft fuel prices have in the past, and may in the future, experience substantial volatility. We cannot predict the future availability, price volatility or cost of aircraft fuel. For more discussion, see Part I, Item 1A. Risk Factors – “Our business is very dependent on the price and availability of aircraft fuel. Continued periods of high volatility in fuel costs, increased fuel prices or significant disruptions in the supply of aircraft fuel could have a significant negative impact on consumer demand, our operating results and liquidity.” Seasonality and Other Factors Due to the greater demand for air travel during summer months, revenues in the airline industry exhibit seasonal patterns based on peak travel periods. General economic conditions, fears of terrorism or war, fare initiatives, fluctuations in fuel prices, labor actions, weather, natural disasters, outbreaks of disease, geopolitical factors and other factors could impact this seasonal pattern. Therefore, our quarterly results of operations are not necessarily indicative of operating results for the entire year, and historical operating results in a quarterly or annual period are not necessarily indicative of future operating results. Domestic and Global Regulatory Landscape General Airlines are subject to extensive domestic and international regulatory requirements. Domestically, the U.S. Department of Transportation (DOT) and the FAA exercise significant regulatory authority over air carriers. The DOT, among other things, oversees and regulates domestic and international codeshare agreements, international route authorities, competition and consumer protection matters including accessibility, the display and sharing of ancillary fee information and refund practices. The Antitrust Division of the Department of Justice, along with the DOT in certain instances, has jurisdiction over airline antitrust matters. The FAA similarly exercises safety oversight and regulates most operational matters of our business, including how we operate and maintain our aircraft. FAA requirements cover, among other things, required technology and necessary onboard equipment; systems, procedures and training necessary to ensure the continuous airworthiness of our aircraft; safety measures and equipment; crew scheduling limitations and experience requirements; and many other technical aspects of airline operations. Additionally, our pilots and other employees are subject to rigorous certification standards, and our pilots and other crew members must adhere to flight time and rest requirements. 16 Table of Contents The FAA also controls the national airspace system, including operational rules and fees for air traffic control (ATC) services. The efficiency, reliability and capacity of the ATC network have a significant impact on our costs and on the timeliness of our operations. The U.S. Postal Service has jurisdiction over certain aspects of the transportation of mail and related services. Airport Access and Operations Domestically, any U.S. airline authorized by the DOT is generally free to operate scheduled passenger service between any two points within the U.S. and its territories, with the exception of certain airports that require landing and take-off rights and authorizations (slots) and other facilities, and certain airports that impose geographic limitations on operations or curtail operations based on the time of day. Operations at three major domestic airports we serve (John F. Kennedy International Airport (JFK) and LaGuardia Airport (LGA) in New York City, and Ronald Reagan Washington National Airport (DCA) near Washington, D.C.) and many foreign airports we serve (including LHR) are regulated by governmental entities through allocations of slots or similar regulatory mechanisms that limit the rights of carriers to conduct operations at those airports. Each slot represents the authorization to land at and take off from the particular airport during a specified time period. In addition to slot restrictions, operations at DCA and LGA are also limited based on a so-called “perimeter rule” which generally limits the stage length of the flights that can be operated from those airports to 1,250 and 1,500 miles, respectively. Generally, our ability to retain slots is conditioned on the continued use of such slots, and in the absence of use, the slots are subject to forfeiture. In certain circumstances, such as during the COVID-19 pandemic, regulators may issue slot waivers which temporarily suspend or amend slot usage requirements, and we have used slot waivers at times to reduce flying levels during periods of reduced demand for travel. Moreover, the FAA has issued slot waivers for New York City area airports as a result of operational challenges arising from ATC staffing shortages; those waivers are now set to expire in October 2026. We cannot guarantee that such waivers will be made available to us, or that upon expiration or cancellation of such waivers, it will be economical for us to resume prior levels of flying to destinations where we have operated a reduced service. If we are forced to surrender slots or other rights, we may be unable to provide our desired level of service to or from certain destinations in the future. For more discussion, see Part I, Item 1A. Risk Factors – “If we are unable to obtain and maintain adequate facilities and infrastructure throughout our system and, at some airports, adequate slots, we may be unable to operate our existing flight schedule and to expand or change our route network in the future, which may have a material adverse impact on our operations.” Our ability to provide service can also be impaired at airports where the airport gates and other facilities are currently inadequate to accommodate all of the service that we would like to provide, or where we have no access to gates at all. Existing law also permits domestic local airport authorities to implement procedures and impose restrictions designed to abate noise, provided such procedures and restrictions do not unreasonably interfere with interstate or foreign commerce or the national transportation system. In some instances, these restrictions have caused curtailments in service or increases in operating costs. Airline Fares, Taxes and User Fees Airlines are permitted to establish their own domestic fares without governmental regulation. The DOT maintains authority over certain international fares, rates and charges, but only applies this authority on a limited basis. In addition, international fares, rates and charges are sometimes subject to the jurisdiction of the governments of the foreign countries which we serve. Airlines are obligated to collect a federal excise tax, commonly referred to as the “ticket tax,” on domestic and international air transportation, and to collect other taxes and charge other fees, such as foreign taxes, security fees and passenger facility charges. Although these taxes and fees are not our operating expenses, they represent an additional cost to our customers. These taxes and fees are subject to increase from time to time. DOT Passenger Protection Rules The DOT regulates airline interactions with passengers through the ticketing process, at the airport and onboard the aircraft. Among other things, these regulations govern how our fares are displayed online, required customer disclosures, access by disabled passengers, handling of long onboard flight delays and reporting of mishandled bags. On September 4, 2025, the U.S. Government released its Unified Agenda of Regulatory and Deregulatory Actions, outlining planned priorities, timelines and policy directions across federal agencies. The agenda signals DOT’s intent to roll back existing regulations, including the refund rule, ancillary fee rule, compensation rule, and wheelchair rule. DOT 17 Table of Contents has already begun taking action, such as rescinding an Advance Notice of Proposed Rulemaking titled “Airline Passenger Rights,” which sought comments on requiring airlines to provide cash compensation, free rebooking, meal coverage and overnight lodging with related transportation when disruptions are airline-caused. International International air transportation is subject to extensive government regulation, including aviation agreements between the U.S. and other countries or governmental authorities, such as the EU. Moreover, our alliances with international carriers may be subject to the jurisdiction and regulations of various foreign agencies. The U.S. Government has negotiated “open skies” agreements with more than 130 trading partners, which allow unrestricted route authority access between the U.S. and the foreign markets. In addition, foreign countries impose passenger protection rules, which are analogous to, and often meet or exceed the requirements of, the DOT passenger protection rules discussed above. In cases where these foreign requirements exceed the DOT rules, we may bear additional burdens and liabilities. Further, various foreign airport authorities impose slot, noise and curfew restrictions at their local airports. Security All aspects of civil aviation and border security in the U.S. affecting U.S. carriers are controlled or regulated by the federal government through the Transportation Security Administration (TSA) and the U.S. Customs and Border Protection (CBP). The TSA is responsible for the security of the nation’s transportation systems. The TSA’s requirements for aviation security include, among other things, screening of passengers, baggage, cargo, mail, employees and vendors; carriage of federal air marshals at no charge; and continuous background checks of all employees and vendor employees with access to secure areas of airports. Funding for the TSA is provided by a combination of air carrier fees, passenger fees and taxpayer funds. The CBP is responsible for securing the nation’s borders by combining customs, immigration and agricultural protection. The CBP regulatory requirements include the advanced transmission of reservation records, passport and cargo data to facilitate lawful travel and trade into the U.S. Funding for a portion of CBP operations is provided by a combination of fees collected by airlines. Our international service further requires us to comply with host government civil aviation security regimes and foreign border control authorities. In addition to meeting TSA and CBP regulatory requirements, we support programs that enhance security, compliance and operational efficiency while improving the passenger experience. These initiatives include TSA’s Touchless Identity Solution, which enables biometric identity verification at TSA security checkpoints, and CBP’s Enhanced Passenger Processing program, which uses facial recognition to expedite border clearance. We also participate in TSA’s One Stop Security pilot program to streamline security for connecting passengers and CBP’s International Remote Baggage Screening program, which facilitates pre-clearance of baggage for arriving international travelers. Environmental Matters Environmental Regulation The airline industry is subject to various environmental laws and regulations in the U.S. and other countries. U.S. federal laws with a particular effect on our operations include the Airport Noise and Capacity Act of 1990, the Clean Air Act, the Resource Conservation and Recovery Act, the Clean Water Act, the Safe Drinking Water Act and the Comprehensive Environmental Response, Compensation and Liability Act. The U.S. Environmental Protection Agency (EPA) and other federal agencies promulgate regulations that affect our operations. In light of recent announcements and actions by the U.S. Government to reconsider air- and climate-related regulations and policies, the impact of regulatory changes has become increasingly difficult to predict. Additionally, various states have been delegated certain authorities under these aforementioned federal statutes, and many state and local governments have adopted environmental laws and regulations that mirror or are more stringent than federal requirements. Revised underground storage tank regulations issued by the EPA in 2015 have affected certain airport fuel hydrant systems, with modifications of those systems needed to comply with the revised regulations. As part of EPA and state regulations of storm water management, several U.S. airport authorities are trying to limit permitted discharges of deicing fluid into the environment, which can include requiring airlines to help build or reconfigure airport deicing facilities. Additionally, compliance with updated federal and state regulations governing firefighting foams require modifications to the fire suppression systems we operate, as well as those maintained by airports. On November 23, 2022, the EPA also published the final rule for particulate matter emission standards and test procedures for civil aircraft engines, which took 18 Table of Contents effect on December 23, 2022. These or similar regulations could result in increased compliance costs, but at this time we do not expect these costs to be material. Environmental laws include those related to responsibility for potential soil and groundwater contamination. We are conducting ongoing investigation and remediation activities to address environmental conditions at several sites that may have been impacted by our historic operations, including airports and maintenance bases. We anticipate that the ongoing costs of those activities will not materially affect our operations. We employ an environmental management system that provides a systematic approach for monitoring changes to and compliance with environmental regulations, and for managing a broad range of environmental issues, including air emissions, hazardous waste, underground tanks, and aircraft water quality. Global and Domestic Regulation Related to Climate Change Climate change-related regulatory activity and developments may adversely affect our business and financial results by requiring us to adapt to rapidly evolving domestic and international regulations and to achieve GHG emission reductions before cost-effective technologies are available. For example, such regulations may require us or our suppliers to make capital investments to purchase specific equipment or technologies, purchase SAF, pay taxes and fees or otherwise incur additional costs related to our emissions. These trends may also increase our operating costs, including fuel costs. The Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) CORSIA is an international, market-based emissions reduction program adopted by the International Civil Aviation Organization (ICAO) in 2016 and is intended to limit emissions in the international aviation sector from 2021 until 2035 through the purchase of eligible carbon offset credits or the use of eligible renewable fuels. For each year from 2021 through 2032, CORSIA requires airlines to compensate for the growth of carbon dioxide (CO2) emissions from the aviation sector, relative to a predetermined ICAO baseline. ICAO originally defined the baseline as the average emissions from covered flights in 2019 and 2020. However, due to the effect of the COVID-19 pandemic on air travel, in June 2020, ICAO removed 2020 from the baseline calculation for the CORSIA pilot phase (2021-2023). In October 2022, ICAO member countries agreed that 85% of 2019 emissions would be used as the baseline for the remainder of CORSIA’s term (2024-2035). The CORSIA program is being implemented in three phases: a pilot phase that ran from 2021 through 2023, followed by a first phase covering 2024 through 2026 and a second phase beginning in 2027 through 2035. ICAO member countries are expected to enact legislation to implement CORSIA. In December 2025, ICAO confirmed that governments participating in CORSIA are expected to inform airlines of their carbon emissions offsetting requirements for the first year (2024) of CORSIA’s first phase in the near future. Our future costs related to CORSIA compliance are uncertain due to a variety of factors, including the status of the U.S. Government’s implementation of CORSIA with respect to the obligations of aircraft operators to purchase carbon offsets, uncertainty in the growth of covered CO2 emissions, the supply and price of CORSIA-eligible carbon offset credits and the development of the market for eligible renewable fuels. European GHG Emissions Regulations On May 16, 2023, revisions to the EU Emissions Trading System (EU ETS) were published in the Official Journal of the EU. Under these revisions, the allocation of free emissions allowances to aircraft operators was phased out by the end of 2025. Also, by July 2026, the EC will have to undertake a review to determine whether CORSIA sufficiently delivers on the goals of the Paris Agreement. Depending on the outcome of that review, the EU may expand the scope of the EU ETS, which is currently limited to flights within the European Economic Area (EEA), to include any flight departing the EEA. Should the EU expand the EU ETS scope, there could be serious repercussions for our business and the broader industry, and our costs to comply with the EU ETS would likely be significant. The UK and Switzerland have similar emissions trading schemes that often align with the EU ETS; our compliance costs would further increase if both countries followed the EU in extending the scope of their regulation of GHG emissions from aviation. The EU’s ReFuelEU Aviation initiative, which creates a SAF blending mandate for aviation fuel suppliers, took effect January 1, 2025. This regulation requires fuel suppliers to blend minimum shares of SAF with petroleum jet fuel in the fuel delivered to aircraft operators at EU airports. The minimum requirements are 2% from 2025, 6% from 2030, 20% from 2035, 34% from 2040, 42% from 2045 and 70% from 2050. A specific proportion of the fuel mix (an average of 1.2% in 19 Table of Contents 2030-2031, an average of 2% in 2032-2034, a minimum of 5% from 2035 and progressively reaching a minimum of 35% from 2050) must comprise synthetic fuels such as e-kerosene. The UK also adopted a SAF mandate for aviation fuel suppliers, starting January 1, 2025, with minimum requirements that increase linearly from 2% in 2025, to 10% in 2030 and to 22% in 2040. The UK SAF mandate policy includes separate targets for e-kerosene (referred to under the obligation as power-to-liquid fuels), which start from 2028, and a cap, starting in 2027, on the amount of SAF made from hydrotreated fats and oils that fuel suppliers may use to reach the annual blending targets. Nearly all SAF produced today is made from hydrotreated fats and oils, and it is uncertain whether eligible SAF will be available to meet this requirement. While we expect these requirements to increase our fuel costs, it remains uncertain by how much costs will rise, whether those costs can be passed on to customers, and, assuming they can, whether higher prices will affect customer demand. There is also uncertainty regarding how the EU and UK may implement the SAF mandates, including, the extent to which the relevant governments will change their existing policies or adopt new policies such as flexibility mechanisms for suppliers (e.g., book and claim) and revenue certainty programs for SAF producers. Other countries have adopted, or are considering adopting, similar SAF blending mandates. U.S. Emissions Standards for Aircraft Engines In January 2021, the EPA adopted GHG emission standards for new aircraft engines, aligning with the 2017 ICAO aircraft engine GHG emission standards. Similar to the ICAO standards, the EPA’s standards do not apply retroactively to engines on in-service aircraft. Pursuant to the Clean Air Act, the FAA issued a final rule in February 2024 to implement these standards, introducing new fuel efficiency certification regulations. These regulations, which took effect in April 2024, apply to airplanes manufactured after January 1, 2028, as well as to uncertified large business and commercial jet aircraft. Given announcements and actions by the U.S. Government to reconsider air- and climate-related regulations and policies, the future and impact of these new requirements remain uncertain.

Impact of Regulatory Requirements on Our Business Regulatory requirements, including but not limited to those discussed above, affect operations and increase operating costs for the airline industry, including our airline subsidiaries, and future regulatory developments may continue to do the same. For additional information, see Part I, Item 1A. Risk Factors – “Evolving data privacy requirements (in particular, compliance with applicable federal, state and foreign laws relating to handling of personal information about individuals) could increase our costs, and any significant data privacy incident could disrupt our operations, harm our reputation, expose us to legal risks and otherwise materially adversely affect our business, results of operations and financial condition,” “If we are unable to obtain and maintain adequate facilities and infrastructure throughout our system and, at some airports, adequate slots, we may be unable to operate our existing flight schedule and to expand or change our route network in the future, which may have a material adverse impact on our operations,” “Our business is subject to extensive government regulation, which may result in increases in our costs, disruptions to our operations, limits on our operating flexibility, reductions in the demand for air travel, and competitive disadvantages,” “The airline industry is heavily taxed,” “We are subject to many forms of environmental and noise regulation and may incur substantial costs as a result,” and “We are subject to risks associated with climate change, including increased regulation of our GHG emissions, changing consumer preferences and the potential for increased impacts of severe weather events on our operations and infrastructure.” Available Information Use of Websites to Disclose Information Our website is located at www.aa.com.

RISK FACTORS Below are certain risk factors that may affect our business, results of operations and financial condition, or the trading price of our common stock or other securities. We caution the reader that these risk factors may not be exhaustive. We operate in a continually changing business environment, and new risks and uncertainties emerge from time to time. Management cannot predict such new risks and uncertainties, nor can it assess the extent to which any of the risk factors below or any such new risks and uncertainties, or any combination thereof, may impact our business. Risks Related to our Business and Industry Downturns in economic conditions could adversely affect our business. Due to the discretionary nature of business and leisure travel spending and the highly competitive nature of the airline industry, our revenues are heavily influenced by the condition of the U.S. economy and economies in other regions of the world. Unfavorable conditions in these broader economies have resulted, and may result in the future, in decreased passenger demand for air travel, changes in booking practices and related reactions by our competitors, all of which in turn have had, and may have in the future, a strong negative effect on our business. Furthermore, our efforts to increase travel revenue share, including corporate and travel agency revenue share, may not succeed and competitive pressures and shifts in corporate travel preferences could impede our ability to grow this revenue, negatively affecting our business strategy and financial results. We will need to obtain sufficient financing or other capital to operate successfully. Our business plan contemplates continued significant investments related to our fleet, improving the experience of our customers, updating our facilities and deploying technology. Significant capital resources will be required to execute this plan. We estimate that, based on our commitments as of December 31, 2025, our planned aggregate expenditures for aircraft purchase commitments and certain engines on a consolidated basis for calendar years 2026 through 2030 would be approximately $17.5 billion. We may also require financing to refinance maturing obligations and to provide liquidity to fund other corporate requirements. Accordingly, we will need substantial liquidity, financing or other capital resources to finance such aircraft and engines and meet such other liquidity needs. It may be difficult for us to raise additional capital on acceptable terms, or at all, due to, among other factors: our substantial level of existing indebtedness; our non-investment grade corporate credit rating; volatile or otherwise unfavorable market conditions; and the availability of corporate assets to use as collateral for loans or other indebtedness. If we are unable to arrange any such required financing at customary advance rates and on terms and conditions acceptable to us, we may need to use cash from operations or cash on hand to purchase aircraft and engines or fund our other corporate requirements, or may seek to negotiate deferrals for such aircraft and engines with the applicable manufacturers or otherwise defer corporate obligations. Depending on numerous factors applicable at the time we seek capital, many of which are out of our control, such as the state of the domestic and global economies, the capital and credit markets’ view of our prospects and the airline industry in general, prevailing interest rates, and the general availability of debt and equity capital, the financing or other capital resources that we will need may not be available to us, or may be available only on onerous terms and conditions. Furthermore, we hold significant balances of cash and short-term investments, including as necessary to conduct our day-to-day operations, some of which are held in deposit accounts at commercial banks in excess of the government-provided deposit insurance, which could lead to the loss of such excess balances. There can be no assurance that we will be successful in obtaining financing or other needed sources of capital to operate successfully or to fund our committed expenditures. An inability to obtain necessary financing on acceptable terms would limit our ability to execute necessary capital projects and would have a material adverse impact on our business, results of operations and financial condition. Our high level of debt and other obligations may limit our ability to fund general corporate requirements and obtain additional financing, may limit our flexibility in responding to competitive developments and may cause our business to be vulnerable to adverse economic and industry conditions. We have significant amounts of indebtedness and other financial obligations, including obligations to make future payments on flight equipment and property leases related to airport and other facilities, and substantial non-cancelable obligations under aircraft and related spare engine purchase agreements. Moreover, currently a very significant portion of our assets are pledged to secure our indebtedness. Our substantial indebtedness and other obligations, which are generally greater than the indebtedness and other obligations of our competitors, could have important consequences. For example, they may: •make it more difficult for us to satisfy our obligations under our indebtedness; 22 Table of Contents •limit our ability to obtain additional funding for working capital, capital expenditures, acquisitions, investments and general corporate purposes, and adversely affect the terms on which such funding can be obtained; •require us to dedicate a substantial portion of our liquidity or cash flow from operations to payments on our indebtedness and other obligations, thereby reducing the funds available for investment in our business and other purposes; •make us more vulnerable to economic downturns, industry conditions and catastrophic external events, particularly relative to competitors with lower relative levels of financial leverage; •significantly constrain our ability to respond, or respond quickly, to unexpected disruptions in our own operations, the U.S. or global economies, or the businesses in which we operate, or to take advantage of opportunities that would improve our business, operations, or competitive position versus other airlines; •limit our ability to withstand competitive pressures and reduce our flexibility in responding to changing business and economic conditions; •bear interest at floating rates, subjecting us to volatility in interest expenses as interest rates fluctuate; •contain financial covenants, including the requirement to maintain an aggregate of at least $2.0 billion of unrestricted cash and cash equivalents and amounts available to be drawn under revolving credit facilities, as well as collateral coverage ratios and peak debt service coverage ratios; •impact availability of borrowings under revolving lines of credit; and •contain restrictive covenants that could, among other things: ◦limit our ability to merge, consolidate, sell assets, incur additional indebtedness, issue preferred stock, make investments and/or pay dividends; and ◦if breached, result in an event of default under our other indebtedness. Any additional future financing may include the issuance of additional unsecured or secured debt securities, equity securities and equity-linked securities as well as additional bilateral and syndicated secured and/or unsecured credit facilities, among other items. There can be no assurance as to the timing of any such financing transactions, which may be in the near term, or that we will be able to obtain such additional financing on favorable terms, or at all. Any such actions may be material in nature, could result in the incurrence and issuance of significant additional indebtedness or equity and could impose significant covenants and restrictions to which we are not currently subject. The significant number of financings with respect to which such restrictive covenants and provisions apply subjects us to substantial risk of cross-default and cross-acceleration in the event of breach, and additional covenants and provisions could become binding on us should we seek additional liquidity in the future. The obligations discussed above, including those imposed as a result of any additional financings we may undertake, could also impact our ability to obtain additional financing, if needed, and our flexibility in the conduct of our business, and could materially adversely affect our liquidity, results of operations and financial condition. Further, a substantial amount of our long-term indebtedness bears interest at floating interest rates, which tend to fluctuate based on general short-term interest rates, rates set by central banks, the supply of and demand for credit in treasury markets and general economic conditions. We have not entered into any derivative transactions to hedge our interest rate exposure. Accordingly, our interest expense for any particular period will fluctuate based on the relevant benchmark rate and other variable interest rates. To the extent the interest rates applicable to our floating rate debt increase, our interest expense will increase, in which event we may have difficulties making interest payments and funding our other fixed costs, and our available cash flow for general corporate requirements may be adversely affected. If our financial condition worsens, provisions in our credit card processing and other commercial agreements may adversely affect our liquidity. We have agreements with companies that process customer credit card transactions for the sale of air travel and other services. These agreements allow these credit card processing companies, under certain conditions (including, for certain agreements, our failure to maintain certain levels of liquidity), to hold an amount of our cash (referred to as a holdback) equal to some or all of the advance ticket sales that have been processed by that credit card processor, but for which we 23 Table of Contents have not yet provided the air transportation. Additionally, those credit card processing companies may require cash or other collateral reserves to be established. These holdback requirements can be implemented at the discretion of the credit card processing companies upon the occurrence of specific events, including material adverse changes in our financial condition or the triggering of a liquidity covenant. The imposition of holdback requirements, up to and including 100% of relevant advanced ticket sales, would materially reduce our liquidity. Likewise, some of our other commercial agreements contain provisions that allow counterparties to impose less-favorable terms, including the acceleration of amounts due, in the event of material adverse changes in our financial condition. For example, we maintain certain letters of credit as well as insurance- and surety-related agreements under which counterparties may require collateral, including cash collateral. The loss of key personnel whom we depend on to operate our business, or the inability to attract, develop and retain additional qualified personnel could adversely affect our business. We believe that our future success will depend in large part on our ability to attract, develop and retain highly qualified management, technical and other personnel. We may not be successful in attracting, developing or retaining key personnel or other highly qualified personnel. In addition, competition for skilled personnel has intensified and may continue to intensify if overall industry capacity continues to increase and/or we were to incur attrition at levels higher than we have incurred historically. Any inability to attract, develop and retain significant numbers of qualified management and other personnel would have a material adverse effect on our business, results of operations and financial condition. Our business has been and will continue to be materially affected by many changing economic, geopolitical, commercial, regulatory and other conditions beyond our control, including global events that affect travel behavior, and our results of operations could be volatile and fluctuate materially due to changes in such conditions. Our business, results of operations and financial condition have been and will continue to be affected by many changing economic, geopolitical, commercial, regulatory and other conditions beyond our control, including, among others: •actual or potential changes in international, national, regional and local economic, business and financial conditions, including recession, inflation and elevated interest rates; •wars or other conflicts and escalations thereof, terrorist attacks and geopolitical instability; •changes in consumer disposable income, preferences, perceptions, spending patterns and demographics; •changes in the competitive environment due to industry consolidation, changes in airline alliance affiliations and changes in our or our competitors’ commercial strategies; •delays in scheduled aircraft deliveries, unexpected grounding of aircraft or aircraft engines by us or by regulators, or other loss of anticipated fleet capacity, and failure of new aircraft or aircraft-related equipment to receive regulatory approval, be produced or perform as and when expected; •actual or potential disruptions to the U.S. National Airspace System (the ATC system), including due to a government shutdown; •increases in costs of safety, security and environmental measures or costs of complying with new or more onerous consumer protection laws or regulations; •increases in costs related to meeting our stated climate goals or obligations, including costs incurred to migrate to increase use of SAF in lieu of conventional aviation fuel; •disruptions in global trade relations, such as increased tariffs or other trade barriers, that could create additional costs, new supply chain risks or a decrease in the demand for international air travel; •increases in compliance burdens and costs associated with new and emerging national security regulations, including regulations related to access to certain categories of personal information; •outbreaks of diseases or other public health or safety concerns that affect travel behavior, such as occurred during the COVID-19 pandemic; and 24 Table of Contents •adverse weather and natural disasters, including increases in frequency, severity or duration of such disasters, and related costs caused by more severe weather due to climate change. An outbreak of any contagious disease, such as has occurred in the past with COVID-19, the Ebola virus, Middle East Respiratory Syndrome, Severe Acute Respiratory Syndrome, H1N1 influenza virus, avian flu, Zika virus or any other similar illness, if it becomes associated with air travel or persists for an extended period, could materially affect the airline industry and us by reducing revenues and adversely impacting our operations and passengers’ travel behavior. Governments could implement travel restrictions, including testing regimes, “stay at home” and quarantine orders, limitations on public gatherings, or cancellation of public events or take or mandate other actions that could significantly decrease demand for both domestic and international business and leisure travel. There can be no assurance that any mitigating actions we take in response will be sufficient to avert a deterioration in our business, financial condition and results of operations. As a result of these or other conditions beyond our control, our results of operations could be volatile and subject to rapid and unexpected changes. The airline industry is intensely competitive and dynamic. Our competitors include other major domestic airlines and foreign, regional and new entrant airlines, as well as joint ventures formed by some of these airlines, many of which have greater financial or other resources and/or lower cost structures than ours, as well as other forms of transportation, such as rail and private automobiles or alternatives to commuting or business travel including remote or flexible working policies and communication alternatives such as videoconferencing. In many of our markets, we compete with at least one low-cost carrier (including so-called ultra-low-cost carriers). Our revenues are sensitive to the actions of other carriers in many areas, including pricing, scheduling, capacity, fees (including cancellation, change and baggage fees), amenities, loyalty benefits and promotions, which can have a substantial adverse effect on our and industry revenues. These factors may become even more significant when the industry experiences large losses, as airlines under financial stress, or in bankruptcy, may institute pricing or fee structures intended to attract more customers to achieve near-term survival at the expense of long-term viability. Low-cost carriers (including so-called ultra-low-cost carriers) have a profound impact on industry revenues. Using the advantage of low unit costs, these carriers offer lower fares in order to shift demand from larger, more established airlines, and represent significant competitors, particularly for customers who fly infrequently or are price sensitive and therefore tend not to be loyal to any one particular carrier. These low-cost carriers are attempting to continue to increase their market share through growth and consolidation and are expected to continue to affect our revenues and overall performance. We and several other large network carriers have implemented “Basic Economy” fares designed to more effectively compete against low-cost carriers, but we cannot predict whether these initiatives will be successful. Low-cost carriers may also implement, and in some cases have implemented, changes to their strategies or business models that could, and in some cases have, put them in more direct competition with network carriers. Moreover, we may have to compete with other carriers emerging from bankruptcy with lower cost structures. While historically these carriers have provided competition in domestic markets, we have recently experienced new competition from low-cost carriers on international routes, including low-cost airlines executing international long-haul expansion strategies, a trend likely to continue with the introduction of long-range narrowbody aircraft. Additionally, other carriers focused on premium passenger travel are attempting to implement growth strategies. The actions of existing or future carriers, including those described above, could have a material adverse effect on our operations and financial performance. In certain instances, other air carriers operate scheduled service with a business model that relies on FAA Part 135, a regulatory environment that is generally less stringent than the rules applicable to our airline and similar airlines that operate under FAA Part 121, and which provides those airlines certain competitive advantages that Part 121 airlines cannot replicate. We have objected to the DOT and the TSA that the less stringent Part 135 rules were never intended as a basis for scheduled passenger service and that business model should not be permissible, and the agencies’ review is ongoing. While both the DOT and the TSA are actively reviewing these operations, if they ultimately allow scheduled passenger service in any form under Part 135 and the actions of existing or future carriers using that business model, including those described above, it could adversely impact our business, financial condition and results of operations. We provide air travel internationally directly as well as through joint businesses, strategic alliances, codeshare and similar arrangements to which we are a party. While our network is comprehensive, compared to some of our key global competitors, we generally have somewhat greater relative exposure to certain regions (for example, Latin America) and somewhat lower relative exposure to others (for example, Asia). Our financial performance relative to our key competitors will therefore be influenced significantly by macro-economic conditions in particular regions around the world and the relative exposure of our network to the markets in those regions, including the duration of any declines in demand for 25 Table of Contents travel to specific regions as a result of health emergencies, geopolitical instability or other factors, and the speed with which demand for travel to these regions returns. Our international service exposes us to foreign economies and the potential for reduced demand when any foreign country we serve suffers adverse local economic conditions or if governments restrict commercial air services to or from any of these markets. In addition, “open skies” agreements, which are now in place with a substantial number of countries around the world, provide international airlines with open access to U.S. markets, potentially subjecting us to increased competition on our international routes. See also “Our business is subject to extensive government regulation, which may increase our costs, disrupt our operations, limit our operating flexibility, reduce the demand for air travel, and create competitive disadvantages.” To the extent alliances formed by our competitors can undertake activities not available to us, including regulatory approvals, access slots, gates and routes and other matters, our ability to effectively compete may be hindered. Our ability to attract and retain customers is dependent upon, among other things, our ability to offer our customers convenient access to desired markets. Our business could be adversely affected if we are unable to maintain or obtain alliance and marketing relationships with other air carriers in desired markets. American has established a transatlantic joint business with British Airways, Aer Lingus, Iberia and Finnair, a transpacific joint business with Japan Airlines and a joint business relating to Australia and New Zealand with Qantas Airways. We have also established a strategic alliance with Alaska Airlines relating to certain routes and a strategic alliance relating to the Middle East with Qatar Airways. Legal challenges to our joint businesses and strategic alliances could negatively impact our operations and equity value, disrupt our strategic plans and affect our ability to offer competitive services in key markets. In July 2010, in connection with a regulatory review related to our transatlantic joint business, we provided certain commitments to the EC regarding, among other things, the availability of take-off and landing slots at LHR or LGW. The commitments accepted by the EC were binding for 10 years. In anticipation of both the exit of the UK from the EU, commonly referred to as Brexit, and the expiration of the EC commitments in July 2020, the CMA, in October 2018, opened an investigation into the transatlantic joint business. In September 2020 and April 2022, the CMA adopted interim measures that extend the EC commitments until March 2026 in light of the uncertainty and other impacts resulting from the COVID-19 pandemic. In August 2025, the CMA accepted binding commitments and closed the case. The commitments will replace the prior interim measures. These arrangements are important aspects of our international network, and we are dependent on the performance and continued cooperation of the other airlines party to those arrangements. In December 2022, two putative class action lawsuits were filed in the U.S. District Court for the Eastern District of New York alleging that American and JetBlue violated U.S. antitrust law in connection with the previously disclosed Northeast Alliance arrangement. In February 2023, private party plaintiffs filed two additional putative class action antitrust complaints against American and JetBlue in the U.S. District Court for the District of Massachusetts and the U.S. District Court for the Eastern District of New York, respectively. All cases have since been consolidated in the U.S. District Court for the Eastern District of New York. We believe these complaints are without merit and are defending against them vigorously. No assurances can be given as to any benefits that we may derive from any of the foregoing arrangements or any other arrangements that may ultimately be implemented, or whether regulators will, or if granted continue to, approve or impose material conditions on our business activities. Other mergers and other forms of airline partnerships, including regulatory approvals such as antitrust immunity grants, may take place and may not involve us, or could result in unforeseen impacts on the industry generally and our company in particular. Depending on which carriers combine or integrate and which assets, if any, are sold or otherwise transferred to other carriers in connection with any such transactions, our competitive position relative to the post-transaction carriers or other carriers that acquire such assets could be harmed. In addition, as carriers combine through traditional mergers or integrate their operations through other arrangements, their route networks will grow, and that growth will result in greater overlap with our network, which in turn could decrease our overall market share and revenues. Such combination or collaboration is not limited to the U.S. but could include transactions among international carriers in Europe and elsewhere that result in broader networks offered by rival airlines. Additionally, our AAdvantage program, which is an important element of our business, faces significant and increasing competition from the loyalty programs offered by other travel companies, as well as from similar loyalty benefits offered by banks and other financial services companies. Competition among loyalty programs is intense regarding the rewards, fees, required usage, and other terms and conditions of these programs. In addition, we have used certain assets from 26 Table of Contents our AAdvantage program as collateral for the AAdvantage Financing (defined in the accompanying notes to the consolidated financial statements to this Annual Report on Form 10-K), which contains covenants that impose restrictions on certain amendments or changes to certain of our AAdvantage program agreements provided as collateral under the AAdvantage Financing and other aspects of the AAdvantage program. These competitive factors and covenants (to the extent applicable) may affect our ability to attract and retain customers, increase usage of our loyalty program and maximize the revenue generated by our loyalty program. Further, we rely on partners to provide available space for mileage credit redemptions on their aircraft. Should partners not make available enough inventory within their cabins for our members, the attractiveness of our program may be decreased, potentially impacting customer loyalty and program revenue. We may also be impacted by regulations affecting certain of our major commercial partners, including our co-branded credit card partner, or our loyalty program. For example, there has been bipartisan legislation proposed in Congress called the Credit Card Competition Act designed to increase credit card transaction routing options for merchants which, if enacted, could result in a material reduction of the fees levied on credit card transactions. Additionally, the executive branch recently proposed a temporary 10% cap on credit card interest rates and called on Congress to pass legislation establishing a cap. If either of these proposals were enacted through legislation or regulation, they could fundamentally alter the profitability of our agreement with our co-branded credit card partner and the benefits we provide to our consumers through the co-branded credit cards issued by our partner. The Consumer Financial Protection Bureau cautioned companies in December 2024 against what it views as illegal or unlawful credit card practices, including purported devaluation of earned points, hidden conditions and failure to deliver promised benefits. If regulatory or legislative efforts to impose restrictions on airline loyalty programs and regulations against credit card point devaluations were successful, they could materially reduce the revenues we derive from the AAdvantage program and adversely impact our results of operations. Union disputes, employee strikes and other labor-related disruptions may adversely affect our operations and financial performance. Relations between air carriers and labor unions in the U.S. are governed by the RLA. Under the RLA, CBAs generally contain “amendable dates” rather than expiration dates, and the RLA requires that a carrier maintain the existing terms and conditions of employment following the amendable date through a multi-stage and usually lengthy series of bargaining processes overseen by the NMB. As of December 31, 2025, approximately 86% of our employees were represented for collective bargaining purposes by labor unions, and 15% were covered by CBAs that are currently amendable or that will become amendable within one year. For the dates that the CBAs with our major work groups become amendable under the RLA, see “Labor Relations” under Part I, Item 1. Business – “Sustainability – Our People.” In the case of a CBA that is amendable under the RLA, if no agreement is reached during direct negotiations between the parties, either party may request that the NMB appoint a federal mediator. The RLA prescribes no timetable for the direct negotiation and mediation processes, and it is not unusual for those processes to last for many months or even several years. If no agreement is reached in mediation, the NMB in its discretion may declare that an impasse exists and proffer binding arbitration to the parties. Either party may decline to submit to arbitration, and if arbitration is rejected by either party, a 30-day “cooling off” period commences. During or after that period, a Presidential Emergency Board (PEB) may be established, which examines the parties’ positions and recommends a solution. The PEB process lasts for 30 days and is followed by another 30-day “cooling off” period. At the end of this “cooling off” period, unless an agreement is reached or action is taken by Congress, the labor organization may exercise “self-help,” such as a strike, which could materially adversely affect our business, results of operations and financial condition. None of the unions representing our employees presently may lawfully engage in concerted slowdowns or refusals to work, such as strikes, sick-outs or other similar activity, against us. Nonetheless, there is a risk that employees, either with or without union involvement, could engage in one or more concerted refusals to work that could individually or collectively harm the operation of our airline and impair our financial performance. Additionally, some of our unions have brought and may continue to bring grievances to binding arbitration, including those related to wages. If successful, there is a risk these arbitral avenues could result in material additional costs that we did not anticipate. 27 Table of Contents Personnel shortages, and general wage inflation have impacted and are expected to continue to impact our labor costs. We have agreements with the unions representing mainline pilots, flight attendants, passenger service team members, and mechanic and fleet service workgroups. These agreements include significant increases in pay and benefits compared to the prior agreements, in many cases in line with agreements concluded by our large network competitors with their unions. We remain in negotiations for other new labor agreements and anticipate that any new contracts we agree to with our labor groups will include increases in salaries and other benefits, which will increase our labor expense. If we encounter problems with any of our third-party regional operators or third-party service providers, our operations could be adversely affected by a resulting decline in revenue or negative public perception about our services. A significant portion of our regional operations are conducted by third-party operators on our behalf and are principally provided for under capacity purchase agreements. Due to our reliance on third parties to provide these essential services, we are subject to the risk of disruptions to their operations, which has in the past and may in the future result from many of the same risk factors disclosed in this report, such as the impact of adverse economic conditions, the inability of third parties to hire or retain skilled personnel, and other risk factors, such as an out-of-court or bankruptcy restructuring of any of our regional operators. Several of these third-party regional operators provide significant regional capacity that we would be unable to replace in a short period of time should that operator fail to perform its obligations to us. Disruptions to capital markets, labor difficulties, shortages of pilots, mechanics and other skilled personnel and adverse economic conditions in general have subjected certain of these third-party regional operators to significant financial pressures, which have in the past and may in the future lead to bankruptcies among these operators. Periods of volatility in travel demand have the potential to adversely affect our regional operators, some of whom may experience significant financial stress, declare bankruptcy or otherwise cease to operate. We may also experience disruption to our regional operations or incur financial damages if we terminate the capacity purchase agreement with one or more of our current operators or transition the services to another provider. Any significant disruption to our regional operations would have a material adverse effect on our business, results of operations and financial condition. In addition, our reliance upon others to provide essential services on our behalf in our operations may result in our relative inability to control the efficiency and timeliness of contract services. We have entered into agreements with contractors to provide various facilities and services required for our operations, including distribution and sale of airline seat inventory, reservations, provision of information technology and services, regional operations, aircraft maintenance, fueling, catering, ground services and facilities and baggage handling. Similar agreements may be entered into in any new markets we decide to serve. These agreements are generally subject to termination after notice by the third-party service provider. We are also at risk should one of these service providers cease operations temporarily or permanently, and there is no guarantee that we could replace these providers on a timely basis with comparably priced providers, or at all. These third parties have faced challenges retaining and recruiting people with the appropriate skills to meet our requirements. We rely on the operation of complex supply chains and a large number of third parties for the procurement and fulfillment of parts, components, consumable or disposable goods and other products and services essential to our business. We cannot guarantee that, as a result of ongoing or future supply chain disruptions or staffing shortages, we, our third-party partners, or the airports we serve will be able to timely source all of the products and services we require in the course of our business, or that we will be successful in procuring suitable alternatives. Any material problems with the adequacy, efficiency and timeliness of contract services, resulting from financial hardships, personnel shortages or otherwise, could have a material adverse effect on our business, results of operations and financial condition. Any damage to our reputation or brand image could adversely affect our business or financial results. Maintaining a good reputation globally is critical to our business. Our reputation or brand image could be adversely impacted by, among other things, any failure to maintain high ethical, social and environmental sustainability practices for all of our operations and activities, our impact on the environment, public pressure from investors or policy groups to change our policies, customer perceptions of our advertising campaigns, sponsorship arrangements or marketing programs, customer perceptions of our use of social media, customer concerns in the nature of “greenwashing” allegations that may surround any of our advertising campaigns, marketing programs or commercial offerings related to our sustainability initiatives, or customer perceptions of statements made by us, our employees and executives, agents or other third parties. In addition, we operate in a highly visible industry that has significant exposure to social media. Negative publicity, including as a result of misconduct by our customers, vendors or employees, can spread rapidly through social media. Should we not respond in a timely and appropriate manner to address negative publicity, our brand and reputation may be significantly harmed. Damage to our reputation or brand image or loss of customer confidence in 28 Table of Contents our services could adversely affect our business and financial results, as well as require additional resources to rebuild our reputation. Moreover, an outbreak and spread of an infectious disease could adversely impact consumer perceptions of the health and safety of travel, and in particular airline travel, such as occurred during the COVID-19 pandemic. Actual or perceived risk of infection on our flights could have a material adverse effect on the public’s perception of us and may harm our reputation and business. We have in the past, and may in the future, be required to take extensive measures to reassure our team members and the traveling public of the safety of air travel, and we could incur significant costs implementing safety, hygiene-related or other actions to limit the actual or perceived threat of infection among our employees and passengers. However, we cannot assure that any actions we might take in response to an infectious disease outbreak will be sufficient to restore the confidence of consumers in the safety of air travel. We have experienced incidences of aggressive customer behavior and physical confrontation on our flights in the past, certain of which resulted in injuries to our personnel, and we may experience such behavior in the future. If our employees feel unsafe or believe that we are not doing enough to prevent and prosecute such incidents, we could experience higher rates of employee absence or attrition and we may suffer reputational harm which could make it more difficult to attract and retain employees, and which could in turn negatively affect our business, financial condition and results of operations. We are at risk of losses and adverse publicity stemming from any public incident involving our company, our people or our brand, including any accident or other public incident involving our personnel or aircraft, or the personnel or aircraft of our regional, codeshare or joint business operators. We are at risk of adverse publicity from any public incident involving our company, our people or our brand, particularly given the ease with which individuals can now capture and rapidly disseminate information via social media. Such an incident could involve the actual or alleged behavior of any of our employees, contractors or passengers. On January 29, 2025, American Eagle flight 5342 was involved in a fatal accident in Washington, D.C. The Bombardier CRJ700 aircraft operated by PSA was en route to Washington, D.C. from Wichita, Kansas, when it was involved in a midair collision near Ronald Reagan Washington National Airport. We estimate that the accident reduced first quarter 2025 total operating revenues by approximately $200 million, and the families of multiple passengers have filed lawsuits against the U.S. Government, PSA and American seeking unspecified damages. If other aircraft in our fleet or aircraft operated under our brand, were to be involved in an accident, or if our personnel, one of our aircraft, a type of aircraft in our fleet, or the personnel or aircraft of one of our regional operators or an airline with which we have a marketing alliance, joint business or codeshare relationship were to be involved in a public incident, accident, catastrophe or regulatory enforcement action, we could be exposed to significant reputational harm and potential legal liability. The insurance we carry may be inapplicable or inadequate to cover any such incident, accident, catastrophe or action. In the event that our insurance is inapplicable or inadequate, we may be forced to bear substantial losses from an incident or accident. In addition, any such future incident, accident, catastrophe or action involving our personnel, one of our aircraft (or personnel and aircraft of our regional operators, marketing alliance, joint business and codeshare partners), or a type of aircraft in our fleet could create an adverse public perception, which could harm our reputation, result in air travelers being reluctant to fly on our aircraft or those of our regional operators, marketing alliance, joint business or codeshare partners, and adversely impact our business, results of operations and financial condition. Changes to our business model that are designed to increase revenues and reduce costs may not be successful and may cause operational difficulties or decreased demand. We have in the past instituted, and intend to institute in the future, changes to our business model designed to increase revenues and offset costs. These measures include further segmentation of the classes of service we offer, such as Premium Economy service and Basic Economy service, enhancements to our AAdvantage program, charging separately for services that had previously been included within the price of a ticket, changes to our practices and contracts with providers of distribution systems to provide additional content flexibility, commercial practices related to ticket distribution channels, including efforts by us to migrate an increasing portion of our customers to our modern, direct distribution channels in lieu of third party channels, changing (whether it be increasing, decreasing or eliminating) other pre-existing fees, reconfiguration of our aircraft cabins, and efforts to optimize our network including by focusing growth on a limited number of large hubs and entering into agreements with other airlines. For example, in 2020, we eliminated change fees for most domestic and international tickets, which has reduced our change fee revenue, a trend which is expected to continue assuming this policy remains in place. In addition, during the second quarter of 2024 we concluded that certain changes to our distribution strategy contributed to softness in customer bookings relative to our expectations and we reversed many of these measures late in the quarter, and in 2026, we stopped charging for Wi-Fi on most aircraft for AAdvantage members. We may introduce additional initiatives in the future; however, as time goes on, we expect that it will be more difficult to identify and implement additional initiatives. We cannot assure that these measures or any future 29 Table of Contents initiatives will be successful in increasing our revenues or offsetting our costs. Additionally, the implementation of these initiatives may create logistical challenges that could harm the operational performance of our airline or result in decreased demand. Also, our implementation of any new or increased fees, or changes to the operation of or benefits offered by our loyalty program, could reduce the demand for air travel on our airline or across the industry in general, particularly if weakened economic conditions make our customers more sensitive to increased travel costs or provide a significant competitive advantage to other carriers that determine not to institute similar changes. Such changes could result in adverse brand perceptions, reputational harm or regulatory scrutiny. If regulatory or legislative efforts to impose restrictions on airline loyalty programs were successful, they could materially reduce the revenues we derive from the AAdvantage program and adversely impact our results of operations. Our intellectual property rights, particularly our branding rights, are valuable, and any inability to protect them may adversely affect our business and financial results. We consider our intellectual property rights, particularly our branding rights such as our trademarks applicable to our airline and AAdvantage program, to be a significant and valuable aspect of our business. We protect our intellectual property rights through a combination of trademark, copyright and other forms of legal protection, contractual agreements and policing of third-party misuses of our intellectual property. Our failure to obtain or adequately protect our intellectual property or any change in law that lessens or removes the current legal protections of our intellectual property may diminish our competitiveness and adversely affect our business and financial results. Any litigation or disputes regarding intellectual property may be costly and time-consuming and may divert the attention of our management and key personnel from our business operations, either of which may adversely affect our business and financial results. In addition, we use certain of our branding and intellectual property as collateral for various financings, including the AAdvantage Financing, which contain covenants that impose restrictions on the use of such intellectual property and, in the case of the AAdvantage Financing, on certain amendments or changes to our AAdvantage program. These covenants may have an adverse effect on our ability to use such intellectual property. We may be a party to litigation in the normal course of business or otherwise, which could affect our financial position and liquidity. From time to time, we are a party to or otherwise involved in legal proceedings, claims and government inspections or investigations and other legal matters, both inside and outside the United States, arising in the ordinary course of our business or otherwise. We are currently involved in various legal proceedings and claims that have not yet been fully resolved, and additional claims may arise in the future. Legal proceedings can be complex and take many months, or even years, to reach resolution, with the final outcome depending on a number of variables, some of which are not within our control. Litigation is subject to significant uncertainty and may be expensive, time-consuming, and disruptive to our operations. Although we will vigorously defend ourselves in such legal proceedings, their ultimate resolution and potential financial and other impacts on us are uncertain. For these and other reasons, we may choose to settle legal proceedings and claims, regardless of their actual merit. If a legal proceeding is resolved against us, it could result in significant compensatory damages, and in certain circumstances punitive or trebled damages, disgorgement of revenue or profits, remedial corporate measures or injunctive relief imposed on us. If our existing insurance does not cover the amount or types of damages awarded, or if other resolution or actions taken as a result of the legal proceeding were to restrain our ability to operate or market our services, our consolidated financial position, results of operations or cash flows could be materially adversely affected. In addition, legal proceedings, and any adverse resolution thereof, can result in adverse publicity and damage to our reputation, which could adversely impact our business. Additional information regarding certain legal matters in which we are involved can be found in Note 11(e) to AAG’s Consolidated Financial Statements in Part II, Item 8A and Note 10(e) to American’s Consolidated Financial Statements in Part II, Item 8B. We rely heavily on technology and automated systems, including AI, to operate our business and any failure of these technologies or systems could harm our business, results of operations and financial condition. We are highly dependent on existing and emerging technology and automated systems, including AI, to operate our business. These technologies and systems include but may not be limited to our computerized airline reservation system, flight operations and crew scheduling systems, financial planning, management and accounting systems, telecommunications systems, website, maintenance systems and check-in kiosks. In order for our operations to work efficiently, our website and reservation system must be able to accommodate a high volume of traffic, maintain secure information and deliver flight information, as well as issue electronic tickets and process critical financial information in a timely manner. Substantially all of our tickets are issued to passengers as electronic tickets. We depend on our reservation system, which is hosted and maintained under a long-term contract by a third-party service provider, to be 30 Table of Contents able to issue, track and accept these electronic tickets. If our technologies or automated systems are not functioning or if our third-party service providers were to fail to adequately provide technical support, system maintenance or timely software upgrades for any one of our key existing systems, we could experience service disruptions or delays, which could harm our business and result in the loss of important data, increase our expenses and decrease our revenues. Furthermore, certain critical aspects of our operation rely on legacy technological systems which may grow more difficult or expensive to support and maintain over time, and such systems may fail to perform as required or become more vulnerable to malfunction or failure over time. In the event that one or more of our primary technology or systems vendors goes into bankruptcy, ceases operations or fails to perform as promised, replacement services may not be readily available on a timely basis, at competitive rates or at all, and any transition time to a new system may be significant. Our aircraft employ a number of sophisticated radio and satellite-based navigation and safety technologies, and we are subject to risks associated with the introduction or expansion of technologies that could interfere with the safe operation of these flight systems. For example, telecommunications companies are expanding and increasing the commercial and consumer applications of 5G cellular communication networks, and regulators, manufacturers and operators have expressed concerns that certain 5G applications could interfere with certain flight systems. In December 2021, the FAA issued a special airworthiness information bulletin (SAIB), in which it indicated that further testing and assessment is needed regarding the effects of 5G on certain aircraft equipped with radar altimeters, which measure the aircraft’s altitude and guide pilots during landings. While the FAA and the telecommunications industry reached an agreement to delay the full implementation of 5G deployment near airports until 2028, there could be future impacts once the current agreement expires. Additionally, there has been an increase in the reported use of jamming or “spoofing” technologies by bad actors intended to disrupt the operation of GPS navigation and other flight systems by relaying fake or erroneous flight information and signals to crews. These technologies could pose risks to the safe operation of aircraft by diverting pilots’ attention and potentially resulting in operational disruptions. Our technologies and automated systems are not completely protected against events that are beyond our control, including natural disasters, power failures, terrorist attacks, cyberattacks, data theft, defects, errors, equipment and software failures, computer viruses or telecommunications failures. For example, the CrowdStrike-caused systems outage in July 2024 significantly impacted airline operations, including our own, and forced several carriers to ground flights for a prolonged period and incur significant costs associated with reaccommodating and compensating affected passengers. Similarly, in September 2025, hundreds of our flights were delayed or cancelled out of Dallas/Fort Worth International Airport (DFW) when FAA fiberoptic cables were accidentally cut by a third party. When service interruptions occur as a result of any of the aforementioned events, we address them in accordance with applicable laws, rules and regulations. However, substantial or sustained system failures could cause service delays or failures and result in our customers purchasing tickets from other airlines. We cannot assure that our security measures, change control procedures or disaster recovery plans are adequate to prevent disruptions or delays. Disruption in or changes to these technologies or systems could result in a disruption to our business and the loss of important data. Any of the foregoing could result in a material adverse effect on our business, results of operations and financial condition. Additionally, new technologies, such as the use of AI and machine learning, present evolving and significant legal and operational risks for us and our third-party vendors. We use AI and machine learning technologies, including those licensed from third parties, in our technologies and our ability to continue to use such technologies at the scale may depend on access to specific third-party software and infrastructure. We cannot control the availability or pricing of such third-party AI and machine learning technologies, especially in a highly competitive environment, and we may be unable to negotiate favorable economic terms with the applicable providers. If any such third-party AI and machine learning technologies become incompatible with our solutions or are unavailable for use, or if the providers of such models unfavorably change the terms on which their AI technologies are offered or terminate their relationship with us, our solutions may become less appealing to our customers, and our business will be harmed. In addition, to the extent any third party AI and machine learning technologies are used as a hosted service, any disruption, outage, or loss of information through such hosted services could disrupt our operations or solutions, damage our reputation, cause a loss of confidence in our solutions, or result in legal claims or proceedings, for which we may be unable to recover damages from the affected provider. We expect that increased investment will be required in the future to continuously improve our use of AI (including generative AI) and machine learning technologies. As with many technological innovations, there are significant risks involved in developing, maintaining and deploying these technologies and there can be no assurance that the usage of our investments in such technologies will always enhance our products or services or be beneficial to our business, including our efficiency or profitability. Additionally, the development of generative AI technologies is complex, with practical and competitive challenges in achieving desired accuracy, efficiency and reliability. Generative AI training 31 Table of Contents content, algorithms, models, software and other related systems may have limitations, including biases, errors or inability to process or restrict certain data types or scenarios. In particular, if the models underlying our AI and machine learning technologies are incorrectly designed or implemented, or used without sufficient oversight and governance to ensure their responsible use, the performance of our business, as well as our reputation could suffer or we could incur liability resulting from the violation of laws or contracts to which we are a party or civil claims. Further, there is a risk of system failures, disruptions or vulnerabilities compromising the confidentiality of personal data and intellectual property, or the integrity or availability of training content, input content and prompts, as well as generated content, including disinformation and deepfakes. Use of AI technologies could also expose us to intellectual property risks, such as allegations of infringement of third-party patents or copyrights, which could result in significant fees or damages. Our competitors or other third parties may incorporate AI into their products or services more quickly or more successfully than us, which could impair our ability to compete effectively. AI also presents emerging ethical issues, and if our use of AI becomes controversial, we may experience brand or reputational harm, competitive harm or legal liability. For example, with the increased use of AI and social media, adverse publicity, even if unfounded, can be disseminated quickly and broadly without context, making it increasingly difficult for us to effectively respond. The rapid evolution of AI, including existing and proposed government regulation, may require significant resources to develop, test and maintain our AI technologies and services to ensure compliance and minimize adverse impacts. Any limitations or failures relating to any of the foregoing could result in reputational damage, legal liabilities or loss of customer confidence. There can be no assurance that the usage of AI will enhance our strategies or initiatives. Evolving data privacy requirements (in particular, compliance with applicable federal, state and foreign laws relating to handling of personal information about individuals) could increase our costs, and any significant cybersecurity incident could disrupt our operations, harm our reputation, expose us to legal risks and otherwise materially adversely affect our business, results of operations and financial condition. In the normal course of our business, we collect, process, use and disclose personal information about individuals and rely on third party service providers to host or otherwise process personal information. Many federal, state and foreign governmental bodies and agencies have adopted, or are considering adopting, laws and regulations that impose limits on the collection, processing, use, disclosure and security of personal information about individuals. In some cases, such laws and regulations can be enforced by private parties in addition to government entities. In addition, privacy advocacy and industry groups may propose new and different self-regulatory standards or guidance that may legally or contractually apply to us and our vendors. These non-uniform laws, regulations, standards and guidance are complex and currently evolving and can be subject to significant change and interpretation, and may be inconsistently applied and enforced from one jurisdiction to another. Our business requires the secure processing and storage of personal information relating to our customers, employees, business partners and others, and other data such as confidential information. However, like any global enterprise operating in today’s digital business environment, we and our third party service providers have experienced cybersecurity incidents and data breaches. We react and respond to these cybersecurity incidents in accordance with the applicable legal requirements, our own cybersecurity protocols, as well as our commercial partners’ standards (as appropriate), but we cannot ensure that our responses (or those of our partners and service providers) will be sufficient to prevent or mitigate the potential adverse impacts of these cybersecurity incidents, which may be material. There has been heightened legislative and regulatory focus on AI, data privacy and cybersecurity in the U.S., EU, U.K., China and elsewhere, particularly with respect to critical infrastructure providers, including those in the transportation sector. For example, in March 2024, the DOT launched a privacy review of the ten largest U.S. airlines’ collection, handling, maintenance and use of passengers’ personal information, indicating the DOT may seek to increase its regulation, investigation, and enforcement of airlines’ privacy practices, including ours. As a result, we must comply with a proliferating and fast-evolving set of legal requirements in this area, including substantive data privacy and cybersecurity standards as well as requirements for notifying regulators and affected individuals in the event of a cybersecurity incident. In addition, we are subject to an increasing number of reporting obligations in respect of certain cybersecurity incidents. These reporting requirements have been proposed or implemented by a number of regulators in different jurisdictions, may vary in their scope and application, and could contain conflicting requirements. Certain of these rules and regulations may require us to report a cybersecurity incident before we have been able to fully assess its impact or remediate the underlying issue. Efforts to comply with such reporting requirements could divert management’s attention from our cybersecurity incident response and could potentially reveal system vulnerabilities to threat actors. Failure to timely report cybersecurity incidents under these rules could also result in regulatory investigations, litigation, monetary fines, sanctions, or subject us to other forms of liability. 32 Table of Contents Additionally, in 2024, the National Security Division of the Department of Justice (DOJ) issued a new rule, referred to as the “Data Security Program” (DSP), to implement Executive Order 14117 aimed at preventing access to “bulk U.S. sensitive personal data” and “government-related data” by “countries of concern” (including China, Russia, Iran, North Korea, Cuba, and Venezuela) and so-called “covered persons.” The DSP imposes stringent obligations on companies that engage in transactions with persons and companies with a connection to countries of concern including by prohibiting or restricting certain data transfers and data transactions. The DSP is new, complex and has yet to be enforced, and as such, there is a risk that our interpretation of its applicability, scope, and requirements is incorrect, incomplete, or misapplied. Compliance with the DSP may require us to invest heavily in data security and compliance measures, such as implementing and complying with certain security requirements and guidelines and other burdensome recordkeeping, reporting, and auditing requirements. It may also require us to implement new processes, stop or restrict certain data transfers, alter the geographic scope of our operations, cease doing business with certain third parties or using certain tools or vendors, or change how data flows throughout our business, any of which could materially impact our business operations or hinder our ability to grow our business. Finally, non-compliance with the DSP could result in significant civil or criminal penalties, which could materially adversely affect our business, results of operations, and financial condition. Even though we believe we and our third-party service providers are generally in compliance with applicable laws, rules and regulations relating to AI, data privacy and security, the regulatory environment is increasingly challenging as AI, data privacy and cybersecurity laws, rules, regulations, industry standards and other requirements are continually developing. These changing requirements, along with their evolvi∅∅∅∅∅∅∅∅∅∅∅∅∅∅∅∅∅∅∅∅∅∅∅∅∅∅∅∅∅∅∅∅∅∅∅∅

CYBERSECURITY Cybersecurity Risk Management and Strategy The safety and security of our customers and team members is our top priority. This includes working to put in place appropriate administrative, physical and technical cybersecurity safeguards to help protect our assets that keep our operation running and securely store the information in our care. We have developed and implemented a cybersecurity risk management program intended to protect the confidentiality, integrity, and availability of our systems and information. We have created, and assess our program against, an integrated cybersecurity framework using various National Institute of Standards and Technology (NIST) security standards, guidelines and best practices. This does not imply that we meet any particular technical standards, specifications, or requirements, only that we use various NIST security standards, guidelines and best practices to identify, assess, and manage cybersecurity risks relevant to our business. Our cybersecurity risk management program is overseen by our Executive Cybersecurity Risk Group (ECRG) which is comprised of our Chief Digital and Information Officer (CDIO), Chief Financial Officer and Chief Legal Officer. The ECRG, working with our Chief Information Security Officer (CISO), assists the Board of Directors and our senior leadership team in fulfilling their responsibilities for cybersecurity governance, approval and oversight through the periodic reporting and review of security strategy and risk management practices. Our cybersecurity risk management program is integrated into our overall risk management processes and shares common reporting channels and governance processes that apply across the enterprise to other legal, compliance, strategic, operational, and financial risk governance programs. Our cybersecurity risk management program includes: •risk assessments designed to help identify material risks from cybersecurity threats to our critical systems, information, and our broader enterprise information technology environment; •a cybersecurity team principally responsible for managing our (1) cybersecurity risk assessment processes, (2) security controls, (3) vulnerability management program and (4) detection and response to cybersecurity incidents; •the use of external service providers, where appropriate, to assess, test or otherwise assist with aspects of our security controls; •policies, procedures and standards that are utilized to outline expectations, guidelines and best practices for managing cybersecurity risks; •cybersecurity awareness training for our employees, incident response personnel and senior management; •a cybersecurity incident response plan that (1) includes procedures for responding to cybersecurity incidents and (2) is periodically tested through exercises; and •a third-party risk management process for critical information technology service providers, suppliers, and vendors. 50 Table of Contents We are constantly assessing our environment for cybersecurity threats, and we face risks from cybersecurity threats that, if realized, are reasonably likely to materially affect us, including our operations, business strategy, results of operations or financial condition. At the time of this filing, we have not identified risks from known cybersecurity threats, including as a result of any prior cybersecurity incidents, that have materially affected us, including our operations, business strategy, results of operations or financial condition. See Part I, Item 1A. Risk Factors – “Evolving data privacy requirements (in particular, compliance with applicable federal, state and foreign laws relating to handling of personal information about individuals) could increase our costs, and any significant data privacy incident could disrupt our operations, harm our reputation, expose us to legal risks and otherwise materially adversely affect our business, results of operations and financial condition.” Cybersecurity Governance Our Board of Directors considers cybersecurity risk as part of its risk oversight function and has delegated to the Audit Committee oversight of cybersecurity and other information technology risks. In turn, the Audit Committee oversees management’s implementation of our cybersecurity risk management program. The Audit Committee receives quarterly reports from management on our cybersecurity risks. In addition, management updates the Audit Committee, as necessary, regarding any material cybersecurity incidents, as well as certain incidents with lesser impact potential. The Audit Committee reports to the full Board of Directors regarding its activities, including those related to cybersecurity. The full Board of Directors also receives periodic briefings from management on our cybersecurity risk management program. Board of Director members receive presentations on cybersecurity topics from a combination of our CDIO, CISO, Deputy General Counsel – Chief Privacy and Data Protection Officer, internal security staff, external counsel or external experts, as part of the Board of Director’s continuing education on topics that impact public companies. Our management team, including our CDIO, CISO, Deputy General Counsel – Chief Privacy and Data Protection Officer and additional members of the ECRG are responsible for assessing and managing our material risks from cybersecurity threats. The team has primary responsibility for our overall cybersecurity risk management program and supervises both our internal cybersecurity personnel and our retained external cybersecurity consultants. Collectively, our management team has extensive information technology experience, as well as cybersecurity incident response, compliance, oversight, and program management experience. Additionally, certain leaders and personnel within the cybersecurity organization hold industry certifications, such as Certified Information Systems Security Professional or Certified Information Security Manager. Our management team supervises efforts to prevent, detect, mitigate, and remediate cybersecurity risks and incidents through various means, which may include briefings from internal security personnel; threat intelligence and other various sources including external consultants engaged by us. 51 Table of Contents 6,335false1∅∅∅∅∅∅∅∅∅∅∅∅∅∅∅∅∅∅∅∅∅∅∅∅∅∅∅∅∅∅∅∅∅∅∅∅∅

Management’s Discussion and Analysis of Financial Condition and Results of Operations. Actual delivery dates are subject to change, which could be material, based on various potential factors, including production delays by the equipment manufacturers and regulatory concerns. In addition, we have committed to purchase four used Bombardier CRJ900 aircraft which are scheduled to be delivered in 2026. We also have agreements for 47 spare engines to be delivered in 2026 and beyond. 53 Table of Contents We intend to finance future aircraft deliveries and option exercises using long-term debt. See Note 11 to AAG’s Consolidated Financial Statements in Part II, Item 8A and Note 10 to American’s Consolidated Financial Statements in Part II, Item 8B for additional information on aircraft and engine acquisition commitments. Ground Properties At each airport where we conduct flight operations, we have agreements, generally with a governmental unit or authority, for the use of passenger, operations and baggage handling space as well as runways and taxiways. These agreements, particularly in the U.S., often contain provisions for periodic adjustments to rates and charges applicable under such agreements. These rates and charges also vary with our level of operations and the operations of the airport. Additionally, at our hub locations and in certain other cities we serve, we lease administrative offices, catering, cargo, training, maintenance and other facilities. We lease, or have built on leased property, our headquarters and training facilities in Fort Worth, Texas, our principal overhaul and maintenance base in Tulsa, Oklahoma, our regional reservation offices, and administrative offices throughout the U.S. and abroad.

MARKET FOR AMERICAN AIRLINES GROUP’S COMMON STOCK, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES Stock Exchange Listing Our common stock is listed on The Nasdaq Global Select Market under the trading symbol “AAL.” There is no trading market for the common stock of American, which is a wholly-owned subsidiary of AAG. As of February 13, 2026, there were approximately 51,000 holders of record of our common stock. However, because many of the shares of our common stock are held by brokers and other institutions on behalf of stockholders, we believe there are substantially more beneficial holders of our common stock than record holders. Information on securities authorized for issuance under our equity compensation plans will be set forth in our Proxy Statement for the 2026 Annual Meeting of Stockholders of American Airlines Group Inc. (the Proxy Statement) under the caption “Equity Compensation Plan Information” and is incorporated by reference into this Annual Report on Form 10-K. Dividends on Common Stock There were no cash dividend payments during the years ended December 31, 2025 and 2024. If we determine to make any dividends in the future, such dividends that may be declared and paid from time to time will be subject to market and economic conditions, applicable legal requirements and other relevant factors. We are not obligated to continue a dividend for any fixed period, and the payment of dividends may be suspended or discontinued again at any time at our discretion and without prior notice. 55 Table of Contents Stock Performance Graph The following stock performance graph and related information shall not be deemed “soliciting material” or “filed” with the SEC, nor shall such information be incorporated by reference into any future filings under the Securities Act of 1933 or the Exchange Act, each as amended, except to the extent that we specifically incorporate it by reference into such filing. The following stock performance graph compares the cumulative total stockholder returns during the period from December 31, 2020 to December 31, 2025 of our common stock to the New York Stock Exchange (NYSE) ARCA Airline Index and the Standard and Poor’s Financial Services, LLC (S&P) 500 Stock Index. The comparison assumes $100 was invested on December 31, 2020 in our common stock and in each of the foregoing indices and assumes that all dividends were reinvested. The stock performance shown on the following graph represents historical stock performance and is not necessarily indicative of future stock price performance. 12/31/2020 12/31/2021 12/31/2022 12/31/2023 12/31/2024 12/31/2025 American Airlines Group Inc.

Any future determination to enter into a share repurchase program will be at the discretion of the Board of Directors, subject to applicable legal limitations, and will depend upon our results of operations, financial condition, contractual restrictions and other factors deemed relevant by the Board of Directors. 56 Table of Contents Ownership Restrictions AAG’s Certificate of Incorporation, as amended, and Fifth Amended and Restated Bylaws (Bylaws) provide that, consistent with the requirements of Subtitle VII of Title 49 of the United States Code, as amended (the Aviation Act), any persons or entities who are not a “citizen of the United States” (as defined under the Aviation Act and administrative interpretations issued by the DOT, its predecessors and successors, from time to time), including any agent, trustee or representative of such persons or entities (a non-citizen), shall not, in the aggregate, own (beneficially or of record) and/or control more than (a) 24.9% of the aggregate votes of all of our outstanding equity securities or (b) 49.0% of our outstanding equity securities. Our Certificate of Incorporation and Bylaws further specify that it is the duty of each stockholder who is a non-citizen to register his, her or its equity securities on our foreign stock record and provide for remedies applicable to stockholders that exceed the voting and ownership caps described above. In addition, to reduce the risk of a potential adverse effect on our ability to use our NOL carryforwards and certain other tax attributes for federal income tax purposes, and in connection with the expiration in December 2021 of certain transfer restrictions applicable to substantial shareholders contained in our Certificate of Incorporation, the Board of Directors of AAG adopted the Tax Benefit Preservation Plan. The Tax Benefit Preservation Plan was subsequently ratified by our stockholders at the 2022 Annual Meeting of Stockholders of AAG. AAG entered into Amendment No. 1 to the Tax Benefit Preservation Plan to extend the expiration date to October 29, 2027 and the amendment was approved by stockholders at the 2025 Annual Meeting of Stockholders of AAG on June 11, 2025. The Tax Benefit Preservation Plan is designed to reduce the likelihood that we experience an "ownership change” for purposes of Section 382 by deterring certain acquisitions of AAG common stock. There is no assurance, however, that the deterrent mechanism will be effective, and such acquisitions may still occur. In addition, the Tax Benefit Preservation Plan may adversely affect the marketability of AAG common stock by discouraging existing or potential investors from acquiring AAG common stock or additional shares of AAG common stock, because any non-exempt third party that acquires 4.9% or more of the then-outstanding shares of AAG common stock would suffer substantial dilution of its ownership interest in AAG. See Part I, Item 1A. Risk Factors – “AAG’s Certificate of Incorporation, Bylaws and Tax Benefit Preservation Plan include provisions that limit voting and acquisition and disposition of our equity interests and specify an exclusive forum for certain stockholder disputes” and “Our ability to utilize our NOLs and other carryforwards may be limited.” Also see AAG’s Certification of Incorporation and Bylaws, which are filed as Exhibits 3.1, 3.2 and 3.3 hereto, for the full text of the foregoing restrictions and AAG’s Description of the Registrants’ Securities Registered Pursuant to Section 12 of the Securities Exchange Act of 1934, which is filed as Exhibit 4.1 hereto, for a more detailed description. 57 Table of Contents ITEM 6. SELECTED CONSOLIDATED FINANCIAL DATA Selected Consolidated Financial Data of AAG The selected consolidated financial data presented below under the captions “Consolidated Statements of Operations data” and “Consolidated Balance Sheet data” for the years ended and as of December 31, 2025, 2024 and 2023, are derived from AAG’s audited consolidated financial statements. Year Ended December 31, 2025 2024 2023 (In millions, except share and per share amounts) Consolidated Statements of Operations data: Total operating revenues $ 54,633 $ 54,211 $ 52,788 Total operating expenses 53,166 51,597 49,754 Operating income 1,467 2,614 3,034 Net income 111 846 822 Earnings per common share: Basic $ 0.17 $ 1.29 $ 1.26 Diluted 0.17 1.24 1.21 Weighted average shares outstanding (in thousands): Basic 659,964 656,996 653,612 Diluted 661,052 721,300 719,669 Consolidated Balance Sheet data (at end of period): Total assets $ 61,774 $ 61,783 $ 63,058 Debt and finance leases 29,007 30,476 32,902 Pension and postretirement obligations (1) 1,680 2,275 3,171 Operating lease liabilities 6,963 7,068 7,761 Stockholders’ deficit (3,727) (3,977) (5,202) (1)Substantially all defined benefit pension plans were frozen effective November 1, 2012. See Note 9 to AAG's Consolidated Financial Statements in Part II, Item 8A for further information on pension and postretirement benefits. Reconciliation of GAAP to Non-GAAP Financial Measures We sometimes use financial measures that are derived from the consolidated financial statements but that are not presented in accordance with accounting principles generally accepted in the U.S. (GAAP) to understand and evaluate our current operating performance and to allow for period-to-period comparisons. We believe these non-GAAP financial measures may also provide useful information to investors and others. These non-GAAP measures may not be comparable to similarly titled non-GAAP measures of other companies, and should be considered in addition to, and not as a substitute for or superior to, any measure of performance, cash flow or liquidity prepared in accordance with GAAP. We are providing a reconciliation of reported non-GAAP financial measures to their comparable financial measures on a GAAP basis. 58 Table of Contents The following table presents the components of our net special items and the reconciliation of pre-tax income and net income (GAAP measures) to pre-tax income excluding net special items and net income excluding net special items (non-GAAP measures). Management uses these non-GAAP financial measures to evaluate our current operating performance and to allow for period-to-period comparisons. As net special items may vary from period-to-period in nature and amount, the adjustment to exclude net special items provides management with an additional tool to understand our core operating performance. Year Ended December 31, 2025 2024 (In millions) Components of Special Items, Net: (1) Litigation reserve adjustments $ 77 $ — Labor contract expenses (2) 31 605 Severance expenses 44 13 A330 fleet-related adjustments (3) — (42) Other operating special items, net 7 34 Mainline operating special items, net 159 610 Regional operating special items, net (4) 3 33 Operating special items, net 162 643 Mark-to-market adjustments on equity investments, net (5) (40) 8 Debt refinancing and extinguishment 22 16 Other nonoperating special items, net 18 — Nonoperating special items, net — 24 Pre-tax special items, net $ 162 $ 667 Reconciliation of Pre-Tax Income Excluding Net Special Items: Pre-tax income – GAAP $ 190 $ 1,154 Adjusted for: Pre-tax special items, net 162 667 Pre-tax income excluding net special items $ 352 $ 1,821 Reconciliation of Net Income Excluding Net Special Items: Net income – GAAP $ 111 $ 846 Adjusted for: Pre-tax special items, net 162 667 Adjusted for: Net tax effect of net special items (36) (151) Net income excluding net special items $ 237 $ 1,362 (1)See Note 2 to AAG’s Consolidated Financial Statements in Part II, Item 8A for further information on net special items. (2)Labor contract expenses for 2025 included a one-time charge resulting from adjustments to vacation accruals due to pay rate increases effective January 1, 2025, following the ratification of the contract extension in the fourth quarter of 2024 with our mainline maintenance and fleet service team members. Labor contract expenses for 2024 included one-time charges resulting from the ratifications of new CBAs with our mainline flight attendants and passenger service team members, including one-time payments and adjustments to vacation accruals resulting from pay rate increases. (3)In 2024, we entered into a sales agreement for certain Airbus A330 aircraft, resulting in a $42 million gain. These aircraft were previously retired in 2020 as a result of the decline in demand for air travel due to the COVID-19 pandemic. (4)Regional operating special items, net for 2024 included a $33 million non-cash write down of regional aircraft resulting from the decision to permanently park 43 Embraer ERJ145 aircraft. 59 Table of Contents (5)Mark-to-market adjustments on equity investments, net included net unrealized gains and losses associated with certain equity investments. See Note 8 to AAG’s Consolidated Financial Statements in Part II, Item 8A for further information related to our equity investments. Additionally, the table below presents the reconciliation of total operating costs (GAAP measure) to total operating costs excluding net special items and fuel (non-GAAP measure) and total operating cost per available seat mile (CASM) to CASM excluding net special items and fuel. Management uses total operating costs excluding net special items and fuel and CASM excluding net special items and fuel to evaluate our current operating performance and for period-to-period comparisons. The price of fuel, over which we have no control, impacts the comparability of period-to-period financial performance. The adjustment to exclude net special items and fuel provides management with an additional tool to understand and analyze our non-fuel costs and core operating performance. Amounts may not recalculate due to rounding. Year Ended December 31, 2025 2024 Reconciliation of CASM Excluding Net Special Items and Fuel: (In millions) Total operating expenses – GAAP $ 53,166 $ 51,597 Operating net special items (1): Mainline operating special items, net (159) (610) Regional operating special items, net (3) (33) Aircraft fuel and related taxes (10,718) (11,418) Total operating expenses, excluding net special items and fuel $ 42,286 $ 39,536 (In millions) Total Available Seat Miles (ASM) 299,411 292,948 (In cents) CASM 17.76 17.61 Operating net special items per ASM (1): Mainline operating special items, net (0.05) (0.21) Regional operating special items, net — (0.01) Aircraft fuel and related taxes per ASM (3.58) (3.90) CASM, excluding net special items and fuel 14.12 13.50 (1)See Note 2 to AAG’s Consolidated Financial Statements in Part II, Item 8A for further information on net special items. 60 Table of Contents Selected Consolidated Financial Data of American The selected consolidated financial data presented below under the captions “Consolidated Statements of Operations data” and “Consolidated Balance Sheet data” for the years ended and as of December 31, 2025, 2024 and 2023, are derived from American’s audited consolidated financial statements.
