American Airlines, Inc., operating as American Airlines (AA), is a major U.S. airline and a subsidiary of AMR Corporation. It is headquartered in Fort Worth, Texas, adjacent to its largest hub at Dallas/Fort Worth International Airport. American Airlines operates an extensive international and domestic network, with scheduled flights throughout North America, the Caribbean, South America, Europe, and Asia/Pacific. On November 29, 2011, AMR Corporation filed for Chapter 11 bankruptcy protection. Chairman and CEO Gerard Arpey stepped down and was replaced by company president Thomas W. Horton.
 
Dallas/Fort Worth is the airline's largest hub, with AA and American Eagle, AMR's regional carrier, accounting for about 85% of the traffic and 83% of the landing fees at the airport and traveling to more destinations than from its other hubs. American currently operates maintenance bases at Tulsa (TUL) and Fort Worth Alliance (AFW).
 
American Airlines has two affiliates: American Eagle, which is a 100% regional subsidiary, and AmericanConnection, which is the code-share regional brand.

History
Formation
American Airways was developed from a conglomeration of 82 small airlines through acquisitions in 1930 and reorganizations: initially, American Airways was a common brand by a number of independent carriers. These included Southern Air Transport in Texas, Southern Air Fast Express (SAFE) in the western US, Universal Aviation in the Midwest (which operated a transcontinental air/rail route in 1929), Thompson Aeronautical Services (which operated a Detroit-Cleveland route beginning in 1929) and Colonial Air Transport in the Northeast. Like many early carriers, American earned its keep carrying US Mail.
 
American Airlines before World War II
In 1934, American Airways Company was acquired by E.L. Cord, who renamed it "American Air Lines". Cord hired Texas businessman C.R. (Cyrus Rowlett) Smith to run the company.
 
Smith worked with Donald Douglas to develop the DC-3, which American Airlines was the first carrier to fly, beginning in 1936. American's introduction of the DC-3 made it the first airline to be able to operate a route that could earn a profit solely by transporting passenger; other carriers could still not earn a profit without carrying US Mail. With the DC-3, American began calling its aircraft "Flagships" and establishing the Admirals Club for valued passengers. The DC-3s had a four-star "admiral's pennant" outside the cockpit window while the aircraft was parked, one of the most well-known images of the airline at the time.
 
American Airlines was first to cooperate with Fiorello LaGuardia to build an airport in New York City, and partly as a result became owner of the world's first airline lounge at the new LaGuardia Airport (LGA), which became known as the Admirals Club. Membership was initially by invitation only, but a discrimination suit decades later changed the club into a paid club, creating the model for other airline lounges.
 
Postwar Developments
After World War II, American acquired American Export Airlines, renaming it as American Overseas Airways, to serve Europe. AOA was sold to Pan Am in 1950. AA launched another subsidiary, Líneas Aereas Americanas de Mexico S.A., to fly to Mexico and built several airports there. American Airlines provided advertising and free usage of its aircraft in the 1951 film Three Guys Named Mike. Until Capital merged into United in 1961 AA was the largest American airline, which meant second largest in the world, after Aeroflot.
 
American Airlines was under pressure to enter the jet age so they orderd British Built De-haviland Comets. The orders were cancelled when the Comets started to get serious metal fatigue. American Airlines introduced transcontinental jet service with Boeing 707s on January 25, 1959. With its 707s American shifted to nonstop coast-to-coast flights, although it maintained feeder connections to cities along its old route using smaller Convair 990s and Lockheed Electras. American invested $440 million in jet aircraft up to 1962, launched the first electronic booking system (Sabre) with IBM (the basis of today's Travelocity) and built an upgraded terminal at Idlewild (now JFK) Airport in New York City which became the airline's largest base. In the 1960s, Mattel released a series of American Airlines stewardess Barbie dolls, signifying their growing commercial success. Vignelli Associates designed the AA eagle logo in 1967. Vignelli attributes the introduction of his firm to American Airlines to Henry Dreyfuss, the legendary AA design consultant. The logo is still in use today.
 
By September 1970, American Airlines was offering its first long haul international flights from St. Louis, Chicago, and New York to Honolulu and on to Sydney and Auckland via American Samoa and Nadi.
 
A fictitious "American Airlines Space Freighter", the Valley Forge, was the setting for the 1971 science fiction movie Silent Running, starring Bruce Dern and directed by Douglas Trumbull. The freighter featured the then-new "AA" logo on the hull, along with the crew uniforms and several set pieces.
 
In 1971, American acquired Trans Caribbean Airways.
 
On March 30, 1973, American became the first major airline to employ a female pilot when Bonnie Tiburzi was hired to fly Boeing 727s. American Airlines has been innovative in other aspects initiating several of the industry's major competitive developments including computer reservations systems, frequent flyer loyalty programs and two-tier wage scales.

The Admirals Club was conceived by AA president C.R. Smith as a marketing promotion shortly after he was made an honorary Texas Ranger. Inspired by the Kentucky colonels and other honorary organizations, Smith decided to make particularly valued passengers "admirals" of the "Flagship fleet" (AA called its aircraft "Flagships" at the time). The list of Admirals included many celebrities, politicians and other VIPs, as well as more "ordinary" customers who had been particularly loyal to the airline.
 
There was no physical Admirals Club until shortly after the opening of LaGuardia Airport. During the airport's construction, New York Mayor Fiorello LaGuardia had an upper-level lounge set aside for press conferences and business meetings. At one such press conference, he noted that the entire terminal was being offered for lease to airline tenants; after a reporter asked whether the lounge would be leased as well, LaGuardia replied that it would, and a vice president of AA immediately offered to lease the premises. The airline then procured a liquor license and began operating the lounge as the "Admirals Club" in 1939.
 
The second Admirals Club opened at Washington National Airport. Because it was illegal to sell alcohol in Virginia at the time, the Club contained refrigerators for the use of its members, so they could store their own liquor at the airport. For many years, membership in the Admirals Club (and most other airline lounges) was by the airline's invitation. After a passenger sued for discrimination, the Club (and most other airline lounges) switched to a paid membership program.
 
Membership now costs $300 to $450 a year, depending on AAdvantage frequent flyer program level (and annual renewal membership costs $250–$400); membership can also be purchased with AAdvantage miles. As of December 2010, passengers can buy a 24-hour pass for $50. American Express Platinum Cardmembers receive access to the Admirals Club as a benefit of their membership.
 
Flagship Lounge
Though affiliated with the Admirals Club and staffed by many of the same employees, the AA Flagship Lounge is a separate lounge specifically designed for customers flying on premium flights both within the United States and internationally. This means that only First Class passengers on 3-class aircraft, both Internationally and Transcontinentally, are granted entrance to these clubs. A 3-class aircraft operating a non-transcon AFS flight and not sold as 3-class is not considered Premium, and entrance is not granted to passengers on this type of service. Lounge access is granted to passengers on non-AA operated flights flown by select airline partners as well, again, as long as the flight has a true International First Class cabin and the passenger is booked in that class as a paying customer or on a premium cabin frequent flyer award ticket (not as an upgrade). The only exception to this rule is for OneWorld Emerald elite FF members (including AA Executive Platinum) on international flights (excluding Canada, the Caribbean, and Mexico except Mexico City), and non-AAdvantage OneWorld Emerald elite FF members on 'domestic' flights, who are granted access to the lounges travelling in any class.
 
The added amenities of the Flagship Lounges compared to the normal Admirals Club include free alcoholic beverages including premium brands not found in the Admirals Club, free premium buffet snacks including breakfast items, salads, sandwiches, fruits, chocolates, cheeses and other light fare (options change based on time of day), as well as a less crowded, more comfortable lounge space. Additionally, complimentary Lenovo computer terminals with free internet access, complimentary T-Mobile hotspot access, and complimentary printing is available at most locations, as are shower facilities.
 
The first Flagship Lounge was opened at Dallas Fort Worth International Airport as a courtesy to First Class customers preparing for long flights to London and Tokyo. While the Dallas lounge is no longer open, Flagship Lounges are now available at four airports: Chicago-O'Hare, London-Heathrow, Los Angeles and New York-JFK.
