While on a flight we were told that if we filled out a Spirit MasterCard application we would receive certificate for 2500 on board. This Free Spirit certificate was good no matter the outcome of the application. Over and over again we were told that 2500 miles was enough for a one-way ticket to anywhere they fly. Deceiving if not a all out lie. The only way you can fly one way is off peek flight dates and the only way you can fly on off peak flight dates is if you have a Spirit MasterCard, no card 2500 won't get you anything, next closest match is 10,000 miles for standard flight dates.
