My aunt booked our tickets for our trip in June through them, not from AirTran though. Also, back in 05 we booked through them. I am opposite of CarolA, I have never found booking directly with the airline to be cheaper than Expedia or Travelocity. Could be just the area I live in, not sure. My dad has only a handful of times found booking directly with the airline to be cheaper too. I can't really help you decide if you should do it or not, but that is a good bit of savings. Are you planning on traveling at a time when there could be bad weather problems?
