So, booking a flight on Airtran for winter trip...It will be in early February. The local airport (BMI) is in talks with southwest to see what their plans are, but nothing is firm.

If SW pulls out, I assume I will get my money back. My concern is more around booking another ticket with shorter notice and paying crazy money for it.

Do you think SW would allow me to move to another city nearby w/o charge? I'm not sure how soon SW will pull services out of a given city, but I just want to be prepared.
