2 bonus miles per dollar
Spirit Airlines – a discount air carrier in the U.S. - offers this bonus card to frequent travelers. The card is available in Word Master Card. The card offers a generous rewards rate of 2 miles per $1 on all purchases, however, we can discount the miles because of fees and inconvenience you can find when traveling with Spirit. Users of the card complain about the cost of the tickets if you redeem miles. In a high season, it can go up to 50,000 miles per round trip, comparing to 5,000 miles per trip as advertised.
