Also, the flight times from Huntsville are terrible, in my opinion that is. I would just wait and watch the SW fares from Nashville. More flight times to choose from, and I've always been able to get a fare of less than $200 RT with SW to MCO from Nashville. With Dings! I've gotten as little as 95 RT.
The $249 out of Huntsville is about their average fare, so it is not a deal.
Also, that $249 is before taxes, with taxes it's $268. Just looked at SW, and if you could go Fri and Sunday, instead of Sat - Sat, SW is only 283 inclusive. That's only $15 per ticket difference.
