I agree that it's way too early to decide this. At least wait until Southwest come out with their early December fares, and that won't happen for many months now. Since Oklahoma City is lucky enough to be a Southwest city, you would be well-advised to see what they come out with. They are only selling thru June now, but sampling fares I am seeing under $320 round-trip on Southwest, OKC to MCO (one stop). And frankly, I'd prefer Southwest to most of the other carriers at OKC.
So hold your horses, and plan to fly for now until you know for sure.
Good luck!
