To me it is Skybus, Air Tran and Virgin. There is nothing to say about Skybus. The pay, uniforms and policies are a joke just like the airline. What airlines charges for a soda? Next it is a tie between Air Tran and Virgin. Virgin upgrade is based on how much butt kissing you do. Air Tran is Valujet...enough said. I know 2 people personally that were hired there and they busted almost every checkride at the regional level.
