Just a heads up! If you call to get a credit from AirTran because of a fare drop, and you paid to select your seats, make sure you don't lose that in the process. DH called and got us a credit because the fares dropped $10 for the way down trip. He told me it was a $64 credit which I thought was the $40 plus taxes on it. Boy was I wrong, I went online to double check everything after and they gave me back $24 for the seat selection fees on that flight 
After I had heart failure and thoughts of my kids ending up away from us (it also crossed my mind of a stranger sitting next to my very precocious 5 year old DD trying to skydive off the plane
) DH called them back and got us our original picks back.
Just make sure you don't lose that in the process if it's important to you! But on the up side we have $40 to help offset the luggage fees! woo hoo!
