I booked my flight for August a couple of months ago for $140 each way with SWA out of Buffalo. Hubby and I just decided to do a last minute trip the end of May, and after booking at $126 each way, they dropped to $105 for two days - I would wait and just watch religiously like I do. At least with SWA we can book, then if they go down even more, we get credits for our next trip with no penalties for changing!
