American Airlines, Inc. (AA) is a major United States airline. It operates an extensive international and U.S. domestic network, with scheduled flights throughout North America, the Caribbean, South America, Europe, and Asia. Its route network centers on five hubs at Dallas/Fort Worth, John F. Kennedy International Airport in New York, Los Angeles, Miami, and O’Hare International Airport in Chicago. Its primary maintenance base is located at Tulsa International Airport (TUL). The company is headquartered in Fort Worth, Texas. American Airlines is a member airline 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., Republic Airways Holdings, 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.
The 737-800 is a stretched version of the 737-700, and replaces the 737-400. It also filled the gap left by the decision to discontinue the McDonnell Douglas MD-80 and MD-90 following Boeing’s merger with McDonnell Douglas. The −800 was launched by Hapag-Lloyd Flug (now TUIfly) in 1994 and entered service in 1998. The 737-800 seats 162 passengers in a two-class layout, or 189 in one class, and competes with the A320. For many airlines in the U.S., the 737-800 replaced aging Boeing 727-200 trijets.
The 737-800 is also among the models replacing the McDonnell Douglas MD-80 series aircraft in airline service; it burns 850 US gallons (3,200 L) of jet fuel per hour, or about 80 percent of the fuel needed by an MD-80 on a comparable flight, even while carrying more passengers than the latter. According to the Airline Monitor, an industry publication, a 737-800 burns 4.88 US gallons (18.5 L) of fuel per seat per hour. Alaska Airlines replaced the MD-80 with the 737-800, saving $2,000 per flight, assuming jet fuel prices of $4 per gallon. The fuel cost of each such flight (2008 prices) on a 737-800 is about $8,500.
On August 14, 2008, American Airlines announced 26 orders for the 737-800 (20 are exercised options from previously signed contracts and six are new incremental orders) as well as accelerated deliveries. A total of 2,135 -800, and 16 -800 BBJ aircraft have been delivered with 1,521 unfilled orders as of January 2011. Ryanair, an Irish low-cost airline is among the largest operators of the Boeing 737-800, with a fleet of over 300 aircraft serving routes across Europe and North Africa.
