Frontier Airlines is a Denver-based ultra-low-cost carrier flying to over 100 destinations across the U.S., Mexico, the Caribbean, and Central America. Frontier's base fares are among the lowest in the industry, but the total cost depends heavily on which extras you add — bags, seat selection, and carry-ons all carry fees. FaresMatch advisors can help you compare Frontier fares against other carriers and make sure you're seeing the full picture before you book.

Tips for booking cheap Frontier flights
Frontier's base fare looks very cheap, but carry-on bags, checked bags, and seat selection all cost extra. A carry-on can add $30–$60 each way. Always calculate the full price before comparing to other airlines.
If you can fit everything in a small personal item (under-seat bag), Frontier's base fare gives you a genuinely cheap ticket with no add-ons needed.
Frontier's cheapest fares go fast. Booking 6 to 8 weeks out on leisure routes typically secures the best prices before they step up.
Frontier's Discount Den membership gives access to the lowest fares and sale prices year-round. If you fly Frontier regularly, the annual fee can pay for itself quickly.

Frequently asked questions
How do I book Frontier Airlines through FaresMatch?
Use the search widget above or call a FaresMatch advisor. Our agents compare Frontier fares alongside other carriers so you can see whether Frontier's total cost (with bags and fees) is genuinely the cheapest option for your route.
Does Frontier charge for carry-on bags?
Yes — Frontier charges for carry-on bags unless you purchase a bundle or are a Discount Den member. A personal item (small bag that fits under the seat) is always free. Carry-on fees vary by route and how far in advance you add the bag, but typically run $30–$60 each way.
What is Frontier's change and cancellation policy?
Frontier's Basic fare does not allow changes or cancellations. Economy and Premium fares allow changes for a fee, and tickets booked 60+ days out can sometimes be cancelled for a credit. Frontier's all-you-can-fly GoWild pass has its own rules. Always check the fare conditions at booking.
Does Frontier fly internationally?
Yes — Frontier flies to 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 the cheapest day to fly Frontier?
Tuesdays and Wednesdays tend to offer the lowest Frontier fares. Frontier also regularly releases flash sales, so monitoring fares midweek — or asking a FaresMatch advisor to watch for drops — is the best way to catch the lowest prices.
