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. (Envoy), 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.

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, Madrid, Seattle/Tacoma, Sydney and Tokyo (among others).

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), SkyWest Airlines, Inc. (SkyWest), and Mesa Airlines, Inc. (Mesa). In addition, Compass Airlines, LLC operated regional jet aircraft for us during 2020; however, this arrangement ended in April 2020. Our regional carriers are an integral component of our operating network. We rely heavily on regional carriers to drive feeder traffic to our hubs from low-density 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 2020, approximately 302021, 49 million passengers boarded our regional carriers’ planes, approximately 48%44% of whom connected to or from our mainline flights, a decrease from approximately 59 million passengers in 2019, due to the effects of the COVID-19 pandemic.

Our cargo division provides a wide range of freight and mail services, with facilities and interline connections available across the globe. In 2020, we expanded our cargo service and launched our first cargo-only flights since 1984 to transport critical goods, including the COVID-19 vaccine,vaccines, between the U.S. and Europe, Asia and Latin America. WeSince March 2020, we have operated more than 5,20010,000 cargo-only flights serving 41approximately 30 destinations. These cargo-only flights have helped our customers move more than 167350 million pounds of critical goods around the world amidst the COVID-19 pandemic.pandemic and the related pandemic-driven supply chain challenges.

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, each of which has been granted antitrust immunity. 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. American and its joint business partners received regulatory approval to enter into these cooperation agreements. 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. Our competitors, including Delta Air Lines and United Airlines, are party to similar arrangements.

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 generally provide enhanced customer choice by means of an expanded network with reciprocal loyalty program participation and joint sales cooperation. As of December 31, 2020,2021, American had codeshare and/or loyalty program relationships with Aer Lingus, Air Tahiti Nui, Alaska Airlines, British Airways, Cape Air, Cathay Pacific, China Southern Airlines Company Limited (China Southern Airlines), EL AL Israel Airlines, Etihad Airways, Fiji Airways, Finnair, GOL Linhas Aéreas Inteligentes S.A. (GOL), Gulf Air, Hawaiian Airlines, Iberia, Interjet Airlines,IndiGo, Japan Airlines, Jetstar Airways, Jetstar Japan, JetBlue Airways Corporation (JetBlue), Korean Air Lines, Malaysia Airlines, Qantas, Qatar Airways, Royal Air Maroc, Royal Jordanian Airlines, S7 Airlines, Seaborne Airlines,Silver Airways, SriLankan Airlines and Vueling Airlines.

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, 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 on such routes. We also compete with all-cargo and charter airlines and, particularly on shorter segments, ground and rail transportation.

The airline business is labor intensive, and our team members are our most important asset. The operational complexity of our business requires a diverse 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. We believe that if we create an environment where our team members feel supported, they will take care of our customers and thereby support the success of our business. To do this, we must continue to build a diverse and inclusive environment, helping all team members reach their full potential and providing them with the right resources and support.

We give our team members the tools, training and resources they need to do their best work and stay true to our purpose – caring for people on life’s journey.work. We have a suite of programs aimed at helping our people develop the skills and experience to succeed in their roles and build rewarding, long-term careers within our company. Additionally, we’ve partnered with leading online learning platforms to make professional development available on-demand to all our team members.

Due to the greater demand for air travel during the summer months, revenues in the airline industry in the second and third quarters of the year tend to be greater than revenues in the first and fourth quarters of the year. General economic conditions, fears of terrorism or war, fare initiatives, fluctuations in fuel prices, labor actions, weather, natural disasters, outbreaks of disease 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.

Airlines are subject to extensive domestic and international regulatory requirements. Domestically, the DOT and the Federal Aviation Administration (FAA) exercise significant regulatory authority over air carriers.

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 and rates are sometimes subject to the jurisdiction of the governments of the foreign countries which we serve.

The DOT regulates airline interactions with passengers through the ticketing process, at the airport and on board 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. In 2021,2022, the DOT is expected to propose or implement a number of new regulations that will impact us, including disability rules for accessible lavatories and wheelchair assistance, refund requirements, display of ancillary fees during initial flights search, and refunds for checked bag fees in the event of certain delays in delivery.

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 and the United Kingdom. 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 130 trading partners, which allow unrestricted route authority access between the U.S. and the foreign markets. While the U.S. has worked to increase the number of countries with which open skies agreements are in effect, a number of markets important to us, including China, do not have open skies agreements.

Since shortly after the events of September 11, 2001, substantially all aspects of civil aviation security in the U.S. or affecting U.S. carriers have been controlled or regulated by the federal government through the Transportation Security Administration (TSA). Requirements include flight deck security; carriage of federal air marshals at no charge; enhanced security screening of passengers, baggage, cargo, mail, employees and vendors; fingerprint-based background checks of all employees and vendor employees with access to secure areas of airports; and the provision of certain passenger data to the federal government and other international border security authorities, for security and immigration controls. Funding for the TSA is provided by a combination of air carrier fees, passenger fees and taxpayer funds. Customs and Border Protection, which, like the TSA, is part of the Department of Homeland Security, also promulgates requirements, performs services and collects fees that impact our provision of services. Additionally, we have at times found it necessary or desirable to make significant expenditures to comply with security-related requirements while seeking to reduce their impact on our customers, such as expenditures for automated security screening lines at airports. Our international service further requires us to comply with the civil aviation security regimes imposed at the foreign airports we serve.

The airline industry is subject to various laws and government regulations concerning environmental matters in the U.S. and other countries. U.S. federal laws that have a particular impact 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 (Superfund Act). The U.S. Environmental Protection Agency (EPA) and other federal agencies have been authorized to promulgate regulations that have an impact on our operations. In addition to these federal activities, various states have been delegated certain authorities under the aforementioned federal statutes. Many state and local governments have adopted environmental laws and regulations which are similar to or stricter than federal requirements.

Efforts to transition to a low-carbon future have increased the focus by global, regional and national regulators on climate change and greenhouse gas (GHG) emissions. We recognize that air travel impacts the environment and have committed to develop an intermediate, science-based target for reducing GHG emissions by the year 2035 with the goal to achieve net-zero carbon emissions by 2050. In addition to investing in strategic partnerships in an effort to help develop and support emissions-reduction solutions and accelerate clean energy technologies, we have taken a number of actions that mitigate the GHG emitted by our operations both en route and on the ground, such as:
