I am just about to book my October airfare thorugh SWA as the have the best rate with a non-stop flight on the way down but have never flown SWA before. I am a family of five with an infant and was wondering if SWA has seat selection available when you book or do you have to wait until you check in the book your seats? I don't really want to have my family spread all over the place. The rate that I received is $1050 from BUF to MCO and return from RSW to BUF. I was hoping for a DING but nothing has come up yet. If I book tickets now and a DING comes up will SWA credit back the differnece in vouchers on a flight within 12 months?
