It seems that I've read that not to buy Airtran based on schedule. I need to have the latest flight from MCO to BWI on Jan 2nd for my brother and sister in law (teachers that have to be at school the next morning). Southwest has a nonstop leaving at 7:50 for $192 and Airtran has a nonstop leaving at 8:50 for $172. It kind of seems like a no brainer except I have no experience at all with Airtran and I'm curious about the frequency of schedule changes. Any input?
