Personally I think it's high. BWI always has great fares to MCO. I booked my late April 2010 ticket out of Dulles to MCO and got $59 ec way. Generally BWI is lower than Dulles. I guess it depends if you want to buy and get a credit later. I try to avoid the credits myself as I bounce between Jetblue and SW (but prefer Jetblue better). I booked my March 2010 trip on SW out of Dulles and got $54 ec way, and I booked my trip to MCO down on SW for January 2010 and again at $54 one way. So yes, the good fares are still there. However, if you are talking about Memorial Day weekend, maybe that's why the rate is higher. If you plan to buy the early bird on your SW ticket, don't forget to add that cost making that $89 ticket now $99.
