The other thing to keep in mind is that they will start boarding at about 3:50ish...at least that was my experience on my past 4 flights with AirTran. So, you want to be at the gate, all ready to go, no later than 3:30....and earlier is always better. I know I had to rush to get to my gate last Tuesday morning. The security line was backed up, my ride was late in getting me to the airport. By the time I got to the gate, I had about 20 mins before boarding started...just enough time to grab a bottle of water and use the restrooms. By the time I got back to the gate, and sat down to arrange my stuff, they started boarding!!!! Hate cutting it that close.
