American Airlines started in 1930 as American Airways, a company built by joining dozens of small carriers. One of them was Robertson Aircraft Corporation, where Charles Lindbergh had flown the mail. In 1934 the airline was reorganized as American Airlines under C.R. Smith. Working with Donald Douglas, it helped develop the DC-3, the plane that first made carrying passengers profitable for airlines.
In 1939 American opened the world's first airline lounge, the Admirals Club, at New York LaGuardia. It flew the first coast-to-coast jet service in 1959 using the Boeing 707. In the early 1960s it worked with IBM to launch SABRE, an early computer system for booking seats. Under boss Robert Crandall, American perfected the hub-and-spoke model at Dallas/Fort Worth, meaning most flights connect through one big airport.
In 1981 American created AAdvantage, the world's first modern frequent-flyer program, which rewards people who fly often. American bought TWA, the historic transatlantic pioneer, in 2001. Parent company AMR filed for bankruptcy in 2011 and merged with US Airways in December 2013, creating the world's largest airline. American helped found the oneworld alliance in 1999. Its hubs are Dallas/Fort Worth, Charlotte, Miami, Chicago, Philadelphia, Phoenix, Washington, and Los Angeles.
