To keep your FRONTIER Miles active means completing one of the following at least once every 12 months:
- Travel: each time you fly, you’ll earn one mile for each air mile flown.
- Use your Frontier Airlines World Mastercard: Use it for flight purchases, restaurant purchases, or everyday purchases for extra earning potential. If you don't have a Frontier Airlines World Mastercard, apply here.
- Use any of our mileage partners: By providing your FRONTIER Miles number upon booking or purchasing with our partners, you'll earn miles for those purchases. (The purchaser name must match the name on your frequent flyer account.)
For all information about earning miles, visit our Earning Miles Page.
Note: redeeming miles or other miscellaneous adjustments will not extend your expiration of miles.
