Anyone ever flown AirTran? I have only flown southwest but AirTran had much better fares out of Boston. It looks like its non refundable though. So if something comes up and we can't go then we've lost all that airfare- is that right? Or would insurance cover that? Looks like you pay per checked bags each way but you get a seat assignment- wouldn't have to do early bird check in fees. Do the resorts check you in for return flights on AirTran? Thanks!
