I use Allegiant exclusively now. I hate the connecting flights and huge security line, long trek to gates at MCO.
Allegiant is smaller airports, so Sanford is an additional 1/2 hour away with no ME. The plus is direct flights, cost is avg $62 for me, there are three smaller airports nearby I can get to for better flight times and days.
Not having any issue with them except a repair took the plan out of service and a flight was coming in within the hour that they were going to do a turn around cleaning on. So we had to switch planes. Not a big deal, just flew out an hour later. I don't fly in the winter, the last three weeks our area had storms so no delays on our end, there was a cancellation on the Saford end. Not sure why or how they handled it. I know the local flight out was delayed because of that. I never watched to see when they did leave.
