oneworld founding partner and one of the world's largest carriers, American Airlines, holds the title of the world's largest airline by the number of hubs served. The airline, based in Fort Worth, Texas, operates ten hubs across the United States, more than any other major airline. American Airlines commenced operations back in 1936, and through various acquisitions, the carrier has maintained its dominance as one of the 'Big Three American carriers. The airline operates with its mainline fleet, American Airlines, while American Eagle supports its wider operations, providing regional and some domestic / trans-border services. Ten Hubs Under Its Belt With more than 1,000 aircraft operating in the airline's fleet, American in 2024 offered more than 275 million seats (that's almost 3/4 of the US population) on both domestic and international flights. The airline last year alone flew more than 2.1 million flights, which was enough miles to go around the Earth almost 74,000 times. American has extensive international reach, primarily through its oneworld partners, with codeshare and joint ventures inked with airlines including Aer Lingus, Alaska Airlines, British Airways, Cathay Pacific, Finnair, Fiji Airways, Iberia, Japan Airlines, Malaysia Airlines, Qatar Airways, and Royal Air Maroc (among others - this list is not exhaustive). The airline also recently partnered with Porter Airlines to offer more flights to and from the US's northern neighbour. The carrier's fleet is the second largest in the world, and consists of Boeing and Airbus narrowbody aircraft, and an all-Boeing widebody fleet. The airline also has an order for 20 Boom Overture supersonic aircraft, with options for 40 more. The average age of the American Airlines fleet, as per data from ch-aviation, sits the average age at around 14 years. To maintain such an enormous collective of aircraft, the carrier operates four maintenance bases across the country, including Tulsa, Pittsburgh, Dallas/Fort Worth, and Charlotte Douglas. Let's dig into the Airlines' ten hubs scattered across the US: Northeastern Hubs American has an extensive network of flights operating from its three hubs in the Northeast. New York JFK Airport (JFK) and Philadelphia International Airport (PHL) handle the vast majority of its international long-haul flights from this region. LaGuardia Airport supports the airline's operations, offering several high-frequency domestic services across the country. Handling around 12% of all flights at JFK, this places American Airlines as the third largest carrier at the airport, following Delta Air Lines and JetBlue. From JFK, American competes in the top three most popular international destinations, including London Heathrow (LHR), Paris Charles de Gaulle (CDG), and Rome Fiumicino Airport (FCO). Philadelphia operates as a popular gateway for American Airlines in the region, with it being the fifth-largest hub for AA. It is the primary hub in the Northeastern United States and is a popular gateway for flights to and from Europe. American dominates operations at the airport, holding around 46% of all flights. It is present on all of the top ten domestic destinations from the airport, including Orlando, Atlanta, Chicago, Dallas, Boston, Charlotte, Miami, Denver, Los Angeles, and Phoenix. Southern Hubs American Airlines is a leading operator of flights to and from the countries south, being home to four of the airline's busiest hubs. Its home and headquarters in Dallas/Fort Worth International Airport is by far the largest hub in its network, with the airline operating around 66% of all flights from the Texan airport. With up to seven runways at Dallas/Fort Worth operating at any given time, this allows American to operate an extensive network of domestic and international destinations. The airline is present on all the top ten international routes, including those to Cancun, London Heathrow, Mexico City, San Jose del Cabo, Guadalajara, Monterrey, Toronto, Puerto Vallarta, Madrid, and Seoul Incheon. Miami International Airport (MIA), located in the Sunshine State, Florida, is the airline's key gateway to Latin America. American maintains services to Belize City, Buenos Aires–Ezeiza, Barranquilla, Bogotá, Cali, Camagüey, Cancún, Cartagena, Cozumel, Guatemala City, Guayaquil, Havana, Holguín, La Romana, Liberia (CR), Lima, Managua, Medellín–JMC, Mérida, Mexico City, Monterrey, Montevideo, Panama City–Tocumen, Puerto Plata, Punta Cana, Quito, Rio de Janeiro–Galeão, Roatán, San José (CR), San Juan, San Pedro Sula, San Salvador, Santa Clara, Santiago de Chile, Santiago de Cuba, Santiago de los Caballeros, Santo Domingo–Las Américas, São Paulo–Guarulhos, Tegucigalpa/Comayagua, Tulum, Varadero, and Georgetown–Cheddi Jagan. Two other integral hubs for America include Charlotte Douglas International Airport, North Carolina, which holds around 69% market share of all flights. The airport has extensive domestic operations, with a growing number of international flights. Ronald Reagan Washington National Airport (DCA), Virginia, is AA's gateway to the country's capital, Washington D.C. From DCA, the airline operates 27% of all flights, solidifying it as the airport's largest carrier. American is present on DCA's top ten domestic flights, which include Atlanta, Boston, Chicago, Orlando, Miami, Dallas/Fort Worth, Charlotte, Fort Lauderdale, Nashville, and New York LaGuardia. Midwest Hubs Sitting pretty as the airline's sole hub in the Midwest is American Airlines' extensive operations at Chicago O'Hare International Airport. American continues to battle against hometown carrier, United Airlines, which is the breadwinner of most routes at Chicago, dominating over 40% of all flights, versus American with 22%. Nonetheless, Chicago remains an important hub for AA, with the carrier operating against United on all top ten domestic destinations from the airport. American maintains both domestic and international operations at Chicago, with the airline participating in many of the most popular international destinations from the airport. The most popular route, to London Heathrow (LHR), sees American go head-to-head with not only code-share partner British Airways, but also United. Other key markets include Toronto Pearson (YYZ) and Cancun (CUN). From Chicago, American offers seasonal, and year-round international services to Europe (including Athens, Barcelona, Dublin, London–Heathrow, Madrid, Paris–Charles de Gaulle, and Rome–Fiumicino), Latin America & Caribbean (Cancún, Cozumel, Mexico City, Puerto Vallarta, Querétaro, San José del Cabo, Liberia (CR), San José (CR), Guatemala City, Punta Cana, Montego Bay, Aruba, Curaçao, Nassau, Grand Cayman, Providenciales, St. Croix, St. Thomas, and St. Maarten), plus Canada (Calgary, Montréal, Toronto, Vancouver, Halifax, Québec City). Western Hubs Heading west, is the home to the remaining two American Airlines hubs, being Phoenix Sky Harbor International Airport (PHX), and Los Angeles International Airport (LAX). AA is the second largest airline operating at Phoenix, marginally being the world's largest low-cost carrier, Southwest Airlines. Alongside Philadelphia and Charlotte, Phoenix was one of three airports that American Airlines subsequently inherited through its merger with US Airways in 2013. American Airlines holds steady as a popular airline of choice for those traveling to and from the state of Arizona, with AA remaining present on all top ten domestic routes from the airport. These include Denver, Seattle, Chicago, Las Vegas, Los Angeles, Dallas/Fort Worth, Salt Lake City, San Diego, Minneapolis/Saint Paul, and San Francisco. The gateway to the Pacific, Los Angeles International Airport (LAX), is one of the busiest airports on the globe, and serves as the airline's westernmost hub. From LAX, AA operates a total of 15% of all flights from the airport, with a growing number of flights around the Pacific Rim and beyond. Long-haul destinations served by AA from LAX include London Heathrow, Mexico City, San José del Cabo, Sydney, and Tokyo–Haneda. Seasonal flights are added to Auckland, Brisbane, Cancun, Puerto Vallarta, and Vancouver. How American Eagle Supports America's Extensive Network Of Flights As the airline's regional arm, American Eagle has wholly owned subsidiaries including Envoy Air, PSA Airlines, and Piedmont Airlines, alongside third-party carriers which include Republic Airways and SkyWest. The combination of these airlines feeds regional passengers into the airline's top ten hubs, whether it be for point-to-point travel or transiting onto other mainline or regional services. The fleet of American Eagle aircraft, totaling more than half of the airline's overall fleet, according to ch-aviation, has more than 544 aircraft remaining in active service. These are a mix of Embraer 170, Embraer 175, Embraer ERJ 145, Bombardier CRJ700, and CRJ900. Between American Airlines and American Eagle, the combined carrier offers an extensive domestic and international network supporting more than 6,800 flights per day by the airline group. American continues to expand its reach, serving more than 350 destinations worldwide, across 48 countries.
