To prevent your Miles from expiring, you’ll need to have accrual activity on your account at least once every 12 months. Here’s what counts:
- Booking on FlyFrontier.com: Every time you make a Frontier purchase, you can earn up to 20 Miles per $1 spent.
- Using the FRONTIER Airlines World Mastercard: Whether it’s for flights, dining, or everyday spending, using the card helps you earn Miles, which counts as qualifying activity. If you don’t have one yet, you can apply online.
- Earning through mileage partners: When you book or make purchases with Frontier’s partners and include your FRONTIER Miles number, you’ll earn Miles—as long as the name on the purchase matches your FRONTIER Miles account.
Just a heads-up: redeeming miles or other adjustments won’t count toward qualifying activity. For more details, you can always check out the Earning Miles page on Frontier’s website.
