We used them once and never again. We didn't like the fact that we never got updates on our flight changes. I would literally have to go into AirTran's website and check our schedule to see if they changed it on us. As for the price difference, they seem to be higher than what we paid for for our September trip (however we bought our tickets at $79 each way due to a sale that AirTran was having, so I may be a little bit biased because of it) plus the times that they give you are not what we look for (like to leave very early in the am and come home on the last flight out). We decided that we would just go through AirTran's own website for now on. Just keep looking for sales/deals. Good luck.
