My only caution with AirTran is when they change a flight, they fail to notify the customer. Be sure and check your reservation on the website when your dates get close. We leave for DL next saturday. I booked tickets in March . Early August I was double checking all my reservation numbers, etc and found that they had changed my return flight. Initially I we were leaving at 1:20. The new time was 10:15. It has been three weeks since I noticed the change and I have yet to be contacted by AirTran of the change.
Same thing happened in 2005. I had 5 different reservations that I had made for the family w/me as the point of contact. They called 2 days before the flight left to inform that one of the reservations changed. Never notified me on the other 4 reservations.
I'm waiting to see if they contact me in the next week and if not, I'll be filing a complaint. I've never had a problem on the flights themselves, but the customer service leaves something to be desired.
