Well - it appears Air Tran took over ValuJet after the 1996 crash. ATA is another story.
Thank you for the feedback, though. I normally fly American or United ( we love very close to O Hare)

Early years
The airline was established in June 1993 and started operations on October 26, 1993 as Conquest Sun Airlines. It was renamed AirTran Airways in August 1994. At the time, AirTran had a similar name to American Trans Air (otherwise known as ATA) and this led to a confusion over branding.
Following objections from Northwest Airlines to AirTran Airways' entry into the jet carrier business, its parent company signed an agreement with Northwest for the spin-off to shareholders of the non-airline businesses. They became part of a new holding company, AirWays Corporation,
In July 1997, AirWays Corporation announced a merger with ValuJet Airlines. In one of the U.S. airline industry's first reverse mergers, ValuJet was re-named AirTran Airways in 1997. This was done because the firm's public image never recovered from the crash of ValuJet Flight 592. On September 24, 1997 the parent company became AirTran Holdings Inc, and operations under new management began on September 1, 1998.
