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.
