American Airlines, Inc. (AA) is a major U.S. airline headquartered in Fort Worth, Texas. It operates an extensive international and domestic network, with scheduled flights throughout North America, the Caribbean, South America, Europe, and Asia. Its route network centers around five "cornerstone" hubs in Dallas/Fort Worth, New York, Los Angeles, Miami, and Chicago. Its primary maintenance base is located at Tulsa International Airport (TUL).
American Airlines is part 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. Envoy Air, SkyWest, Inc., SkyWest Airlines, and ExpressJet Airlines operate regional flights for American Airlines under the American Eagle brand.
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, although the actual integration of the airlines under a single air operator's certificate will not be completed until a much later date. The combined airline will carry the American Airlines name and branding, and will 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.
