We were scheduled to fly out of Seattle on Thursday morning. When we got to the gate there was a sign saying "We need volunteers!" We asked the person checking us in what they would offer if we volunteered. "They've been offering 3 tickets!" she replied. Thinking that she meant 3 tickets for the two of us, we agreed. The flight needed 6 volunteers, however, so they ended up offering all of us 4 tickets each! We knew that was VERY generous, but weren't about to complain. All 6 of us were talking about it so it's not as if we misunderstood. When we got home and tried to use the first voucher, we were told that we each only had 2! We have called the Air Tran customer service number and they told us there was NO record of that and that they never give more than 2 vouchers. Had we only been offered 2 we would have still volunteered to be bumped, but it makes us very angry to feel we were deceived. I have no complaints whatsoever about the flight and everyone we dealt with at the airport was courteous - it's just the fact that they misled us.
