About Frontier Airlines
Frontier is an ultra-low-cost carrier built around Denver, famous for fares that sometimes cost less than a tank of gas. Like other budget airlines, the base fare is bare-bones — bags and seats cost extra — but for flexible travelers it's one of the cheapest ways to fly in America.

Frontier Airlines FAQs
›Why are Frontier flights so cheap?
Frontier strips the fare to the basics — seat and personal item only. Everything else is optional and paid, which keeps base fares extremely low for light travelers.
›Does Frontier charge for carry-on bags?
Yes — full-size carry-ons and checked bags both cost extra. Buy bags during booking, not at the airport, where prices jump significantly.
›Which airports are Frontier hubs?
Frontier's main base is Denver, with large operations in Las Vegas, Orlando, Philadelphia, Atlanta, and Chicago.
›How do I find cheap Frontier flights?
Frontier's own site has the lowest prices — book early, fly midweek, and pack in a personal item to keep the total under $100 round-trip on many routes.
›What is Discount Den?
Frontier's annual membership program unlocks members-only fares and cheaper bags — worth it if you fly Frontier more than twice a year.
