Okay, I've never flown Southwest and I've booked from SEA to MCO for our vacation. I've seen a couple comments on here that you should book your tickets one way instead of round trip. I booked mine round trip before fully reading this board. Does this mean if a cheaper fair comes out I can't rebook just one leg of our trip but have to rebook both? I'm okay with the current price but I am really hoping I can get an earlier flight time on the way there. The current cost for the better time is too high. Will I be stuck because I booked round trip?
