I have my doubts:
<font face="Verdana, Arial, Helvetica, sans-serif" size="2">Earning Credits: Flight Credit Vouchers will be issued automatically at check-in, along with your Customer Receipt and Boarding Pass at the gate of the originating city of your trip at the rate of one Credit per coach-class flight, and two Credits per Business Class flight (A-class only). For the A-Plus Rewards program, a flight is defined as a trip on AirTran Airways from an origin city to a destination city, including any intermediate stops or connections. A Business Class flight is one for which AirTran Airways' full Business Class fare has been paid; a coach-class flight is one for which any coach fare has been paid. ...</font>
Still, rather than speculate: Do any FT'ers have any experiences with credits for upgrades on AirTran?
