Tips for finding cheap Frontier flights

Personal item is the only free option

Frontier's only free allowance is a personal item (under-seat bag). Carry-ons and checked bags both cost extra. For a truly cheap trip, pack everything into one small bag.

Compare total price, not base fare

A $39 base fare becomes $90+ with a carry-on. Always total up bags and seat fees before deciding Frontier is cheaper than an all-in fare on another airline.

Book 6–8 weeks out

Frontier's cheapest fares are available furthest from departure. Booking 6 to 8 weeks out on leisure routes generally secures the best prices on the most popular corridors.

Watch for GoWild pass deals

Frontier's GoWild all-you-can-fly pass can be exceptional value if you fly frequently. The annual pass gives access to unlimited last-minute seats for a flat annual fee.

Frequently asked questions

Is Frontier Airlines really cheap?

Frontier's base fares are genuinely among the lowest in the U.S., but the total cost depends on whether you need bags, seat selection, or a carry-on — all of which cost extra. For travelers who pack only a personal item and are flexible about seating, Frontier can deliver a very cheap total price. For everyone else, the total can match or exceed a competitor's all-in fare.

Does Frontier Airlines fly internationally?

Yes — Frontier serves select international destinations including Cancun, Los Cabos, Puerto Vallarta, Montego Bay, Nassau, Punta Cana, and several Central American cities. International routes are more limited than the domestic network.

What is Frontier's change and cancellation policy?

Basic fares do not allow changes or cancellations. Economy and Premium bundles allow changes for a fee. Bookings made more than 60 days before departure may be eligible for cancellation credit. The WORKS bundle includes the most flexibility for changes and refunds.

What is Frontier's Discount Den?

Discount Den is Frontier's paid membership program that gives access to the lowest available fares and special sales throughout the year. Members also get the lowest bag fees. For frequent Frontier travelers, the annual fee typically pays for itself within a few bookings.
