I fly a lot for hunting and business and I think the airlines generally do a better job than they are given credit for, but this week I changed my mind. My usual checked baggage is a large Cabelas guide bag and in 100's of flights it has only been measured as "oversized" That is with one or two compact arrow cases and a takedown recurve with and extra set of limbs and hunting gear for most trips. This time the AIRTRAN baggage agent decided the only 2/3rds full bag was "oversized" and pulled and stretched it in each direction individually until she got it to measure 69", 8" oversize. I suggested that she measure it just as it sat there, WITHOUT forcing it to be oversize as by her method it would have been oversize even if it was empty! The bag only weighed 39#'s and I only checked one, so apparently Airtran has decided that they WILL get extra $$$ from their customers by any means, so they charged me $29 and their customer service offered me a $25 discount for a future flight, pretty good business scam, charge customers $29 each way for an bag that isn't oversize and give them $25 to fly Airtran again. I haven't had it happen on any other airline, but if you plan on flying with a gear or duffel bag checked, I would strap or tape it up to its minimum size, so they can't force it into being oversize.
