ATA Airlines, Inc., formerly known as American Trans Air, was an American low-cost scheduled service and charter airline based in Indianapolis, Indiana. ATA operated scheduled passenger flights throughout the US mainland and Hawaii, as well as military and commercial charter flights around the world. ATA was North America’s largest charter airline, and until its shutdown transported more troops for the United States military than any other commercial airline.
In 2008, ATA filed for bankruptcy protection. ATA then announced it was ceasing all services, citing the unexpected loss of a major contract for its military charter business, as a subcontractor of FedEx Express, along with recent increases in jet fuel prices. Southwest Airlines owns and retains all ownership of the operating certificate and all assets held by ATA Airlines including trademarks, logos, etc.
ATA was established in 1973 as American Trans Air (ATA) to provide aircraft for the Ambassadair travel club. ATA received its common-air carrier certificate in 1981. Scheduled service flights began in 1986.
