Have always flown Airtran to Orlando. Always on time or even a few minutes early getting there. We usually leave Orlando a bit late because of fog, but always end up getting home right about the scheduled time. The pilots have always been very pleasant to us and even invite the kids to the cockpit after the flight. You can't beat the price either. You don't get served anything but soda and biscuit(cracker), but by the time we get in the air and have a snack the pilot is telling us to put our belts on as we are approaching Atlanta. We jump on a connecting plane and repeat the same pattern. The flight goes so fast.
I have to admit that price is my deciding factor because I can use the rest for other things. I do hope that Delta will offer a good deal out of Peoria when it starts up in August. I really hate that drive to Bloomington at 4a.m.
