I've flown Southwest on numerous occasions.... don't really care for them or their way of doing things.
AirTran: Business Class felt just about equal to coach on some other carriers (like AA
). I would prefer not to fly them, even if it means flying Delta.
Frontier: I flew them several times pre-Airbus. I was impressed with the service and the employees. The airplanes weren't much to speak of, but the employees were excellent.
