Please Help! :) I've never used bidding sites before. I'm looking for a deal from West Palm Beach, FL to Las Vegas for 12/15 - 12/19. I usually just use Air Tran Sales, but current sale is too expensive & last until 11/13. I'm afraid if I wait for the next sale it will be too late for a 12/15 flight. So how do I do this? jojo3d
