Never heard of them, so I checked it out . . .
Great deals . . .
I looked into it for our December trip. BUT . . . Fort Lauderdale is about a 3 1/2 hour drive to WDW. Add to that the 2.5 hour drive to Port Columbus Airport from our house. So I would be adding about 6 hours of travel time to the trip. Most days the flight is $40 each, each way, oh, and you get into FL at about 10:00 at night. When we fly from our regional airport on Airtran for about $89 each way on sale, airport is 15 minutes from our house, and we fly right into MCO.
Now, for the flight back from California, I may look into it. Or If I were just going to Vero Beach, we may consider it too. Of course, with how I felt about Southwest, I don't know if this is the airline for me . . .
