Frontier Airlines’ miles expire 12 months after account inactivity, which can be extended by earning at least one mile.
Frontier’s terms and conditions specifically state that:
“Miles in a Member’s account do not expire so long as the Member generates accrual activity every twelve months; this includes any purchase activity on the Frontier Airlines World Mastercard. Unredeemed mileage accumulated in your account will expire at the end of the twelve-month period after your last accrual activity date. Other account activity, such as redeeming or other miscellaneous adjustments, will not extend your expiration date.”
