Tips for booking Frontier Airlines flights
Frontier's base fares are among the lowest in the U.S., but carry-on bags, checked bags, and seat selection add up quickly. A FaresMatch advisor compares Frontier's all-in price against Southwest, Spirit, and legacy carriers on your route.
Frontier's "The Works" bundle includes a carry-on bag, checked bag, seat selection, and priority boarding — often cheaper than buying each separately, especially for longer trips.
Frontier's lowest fares appear when booking 2 to 3 months in advance. Last-minute Frontier fares can spike significantly, especially on popular leisure routes to Florida and Las Vegas.
