That's incorrect:
Rapid Rewards Credits can be converted in increments of .25 Credits. Expiration date of newly created A+ Rewards Credits will be the same as the original expiration date of the Rapid Rewards Credits transferred.
The only way to refresh the expiration date is to transfer a full 16 AirTran credits to Southwest.
