Frontier Airlines FRONTIER Miles

Frontier Miles is a revenue-based loyalty program from one of the largest ultra-low-cost carriers in the U.S. Miles expire after 12 months of inactivity. Frontier's business model emphasizes low base fares with add-on fees — the co-branded card waives many of those fees and includes a carry-on bag, significantly changing the value equation. No major flexible points program transfers to Frontier Miles, so the co-branded card is the primary earning vehicle for frequent Frontier flyers.

Honest Assessment: The Frontier card makes most sense for travelers who fly Frontier at least 4–5 times per year and need the carry-on bag waiver. Otherwise, a general travel card with no-fee checked bags may offer better overall value.
