AirTran Airways was an American low-cost airline headquartered originally in Orlando, Florida, then in Dallas, Texas, after its acquisition by Southwest Airlines, into which it was integrated. AirTran operated nearly 700 daily flights, primarily in the eastern and midwestern United States, with its principal hub at Hartsfield-Jackson Atlanta International Airport where it operated nearly 200 daily departures. AirTran's fleet consisted of Boeing 717-200 aircraft, of which it was the world's largest operator, and Boeing 737-700 aircraft. It was fully integrated into Southwest Airlines on December 28, 2014.

The original AirTran Airways, a Boeing 737-200 operator with service to/from Orlando, was founded by AirTran Corporation, the holding company of Mesaba Airlines of Minneapolis, Minnesota, operating as a Northwest Airlink carrier with hubs in Minneapolis and Detroit. In 1994, AirTran Holdings purchased a start up 737 operator named Conquest Sun and renamed the airline AirTran Airways. Conquest Sun, similar to ValuJet, was an airline started by former Eastern Air Lines employees. The original AirTran Airways moved its headquarters to Orlando, Florida, and grew to 11 Boeing 737 aircraft serving 24 cities in the East and Midwest providing low-fare leisure travel to Orlando. In 1995, AirTran Airways was spun off by Mesaba and formed its own independent holding company named Airways Corporation.

On July 10, 1997, ValuJet, Inc., the holding company for ValuJet Airlines, Inc., announced plans to acquire Airways Corporation, Inc., the holding company for AirTran Airways, Inc. of Orlando, Florida. The deal was closed on November 17, 1997.
