Just keep in mind that your flight times could change several times between now and then. Last June, when I saw an awesome price, (same as you) I booked Airtran for our Christmas trip. Well, over the next month and half both our flight to Orlando and our flight home were changed several times. And not by a few minutes, either. Our flight home was changed from 8 am to 2:45pm, then changed a few weeks later to 6 pm. Our flight to FL was changed from 9:15 am to 7:05 am. Then, they got rid of our flight altogether and there were no other nonstops scheduled to MCO that day. A layover was not acceptable (nor did I book a layover; I booked nonstops both ways), so I called and got a full refund. I promptly rebooked with Jetblue. And I will never even consider Airtran again. I know people report other airlines changing their schedules, too, but we have never experienced it with either Jetblue or SW.
