I'm convinced that we can do the flying out of Indianapolis airport...after all my research, it doesn't seem "too" hard 
Are there any real differences or advantages to flying ATA over SOuthwest or vice versa? The prices are the same and ether set of flight times are do-able. At this point I am leaning towards SWA because their cancellation policy is pretty flexible--if the fares go down in Louisville or Nashville, I can cancel the Indy flight and rebook through a more convenient city. If we book with ATA, then we are committed to it because ATA only flies out of Lexington near us.
Any thoughts would be appreciated!
