Once you enroll in our FREE SPIRIT frequent flier program, you'll earn miles whenever you fly with us or by using our many partners.  As you build up your miles, you can then use them for award travel.  And, with some of the lowest redemption levels in the industry, you'll earn award travel even faster!  It’s free to join and takes only a minute when you sign up online. 

By having a FREE SPIRIT account, you will also be able to more quickly book new travel and manage your reservations.
