AirTran Airways was a low-cost airline in the United States that operated from 1993 until 2014, when it was merged into Southwest Airlines.

ValuJet Airlines was an ultra low-cost airline in the United States that operated from 1992 until 1997, when it was rebranded as AirTran Airlines after joining forces with AirTran Airways. It was headquartered in unincorporated Clayton County, Georgia, that operated regularly scheduled domestic and international flights in the Eastern United States and Canada during the 1990s. The company was founded in 1992 and was notorious for its sometimes dangerous cost-cutting measures. All of the airline's planes were purchased used from other airlines; very little training was provided to workers; and contractors were used for maintenance and other services. The company quickly developed a reputation for safety issues. In 1995, the military refused ValuJet's bid to fly military personnel over safety worries, and officials at the FAA wanted the airline to be grounded.
