75% off Promo Code on Frontier with Fares from $37+ Roundtrip for Fall Travel

Take 75% off your next Frontier flight for fall/winter travel. Fares start at just $37 roundtrip.

Use promo code SAVE75 when booking on FlyFrontier.com to take 75% off the base fare for nonstop domestic flights on Tuesdays, Wednesdays, Thursdays, and Saturdays, through December 15, 2018, and Tuesdays/Wednesdays, from January 8 through March 6, 2019. An advanced purchase of 10-days is required and blackout dates apply November 17-27, 2018, and February 19, 2019.

The discount does not apply to taxes nor Frontier's online booking fee, which is labeled a "Carrier Interface Charge". This means some routes still won't have a very big price drop even with the big sticker shock of 75% off. However, there are plenty of routes where we are seeing some big price drops. The discount can also be applied to one-way flights.

If you are unfamiliar with Frontier Airlines, please read our guide on Everything You Need to Know Before You Fly Frontier.

There are specific routes excluded from this promo code sale. You may have to click around to find available dates since Frontier operates about half of the route network on just a few days each week. Click on the fare details for more info on exact dates each route is available.

Tickets must be booked by 11:59 pm ET, October 15, 2018.
