Spirit has announced a $10 discount on round-trip flights departing through October when you purchase your ticket with a MasterCard.

If you’re already planning to book a flight on Spirit, this offer is a nice perk. Before you book, however, compare fares to ensure you can’t find a better price elsewhere, even with the discount.

The deal

To take advantage of the deal, enter MC10 in the promotion code box. The discount is valid on round-trip fares priced $98 or higher for travel through October 31, 2008. Tickets must be booked online by 11:59 p.m. ET December 31, 2007.

All prices, dates, and booking details listed here were valid at the time of publication. Some information may have changed since that time.
