AirTran Airways A+ Rewards is the latest program to add an online auction for members. A+ Rewards members can bid on auction items such as merchandise, trips and events with credits. Before bidding on items, members must register for the auction and log in to their account. If you are the winning bidder, the credits will be deducted from your account. Once made, bids cannot be retracted but you can increase your bid at any time. Current items available for bidding are a Danica Patrick poster and Georgia Aquarium snow globe.
