Airtran's A+ rewards program leaves much to be desired. Try finding seats that qualify. If you can find a seat, it will be available only on their least expensive flights to their least popular destinations. Forget about flying cross country to Vegas, San Fran, Seattle or their Caribbean destinations. Unless you need short distance and uninteresting flights, like from Boston to NY, find another program with a different airline. Further, their credit card customer service is also lacking...

Between my flights and credit card usage, I earn between 8 and 16 A+ points per month.
