Hi Disneymommyof3!
You are in the same predicament that I found myself in a few months ago. (We're flying out of BWI as well)In the past, we've found airfares as cheap as $130.00, on SW, however I kept checking the flights that we want, and the prices were stuck at $197.00 each,tax/fees included. I broke down and bought 'em for that price. Oh yeah, it is on Airtran, which had the only acceptable flights - non-stop departing BWI early sunday and coming home early evening out of MCO the following Sunday. Unforturnately, our airline of choice doesn't have flights on the days/times that we want. To make a long story short, the price of the airfare, on the same flights that we booked, went down $168.00, a few weeks ago!!! My wife, CMFrannie, gave me the old, "I told you so", because she wanted me to wait. The customer service people at AirTran wouldn't budge, because the policy clearly states that any changes made result in a $50.00 charge,(which is true), but they were kind enough to do our seat assigments over the phone, which is nice because, ordinarily, you can only get your seats assigned at check-in. If I were you, I would hold off and buy your tickets later. Hope this helps!!!
