American Airlines, Inc. (AA) is a major United States-based airline, operating an extensive international and domestic network, and is the world's largest airline by passengers flown, fleet size and revenue, and the second-most by number of destinations, only after United Airlines. It operates from its hubs at Dallas/Fort Worth, Charlotte, Los Angeles, John F. Kennedy International Airport in New York, Miami, O'Hare International Airport in Chicago, Philadelphia, Phoenix, and Washington, D.C., while its primary maintenance base is at Tulsa International Airport. The company, which is headquartered in Fort Worth, Texas, also has a significant presence in Boston, London-Heathrow, New York-LaGuardia and San Francisco. The airline primarily competes with Delta, United, and Southwest.
American Airlines is a founding member of the Oneworld airline alliance, and coordinates fares, services, and scheduling with British Airways, Finnair, and Iberia in the transatlantic market and with Japan Airlines and Qantas in the transpacific market. Regional service is operated by independent and subsidiary carriers under the brand name American Eagle.
The former parent company of American Airlines, AMR Corporation, filed for Chapter 11 bankruptcy protection in November 2011, and in February 2013 announced plans to merge with US Airways Group, creating the largest airline in the world. AMR and US Airways Group completed the merger on December 9, 2013, with the new holding company American Airlines Group, Inc. being listed on NASDAQ that day, and the two airlines received a single air operator's certificate on April 8, 2015. The combined airline will carry the American Airlines name and branding, and plans to maintain the existing US Airways hubs in Charlotte, Philadelphia, Phoenix, and Washington, D.C., for a period of at least five years under the terms of a settlement with the US Department of Justice and several state attorneys general.
