Take 75% off your next Frontier flight for fall travel. While not quite as big as the promo code sale from earlier this week, this promo code sale includes more days of the week so more people may be able to take advantage of this deal. Fares start at just $33 roundtrip.

Use promo code SAVE75 when booking on FlyFrontier.com to take 75% off the base fare for nonstop domestic flights on Mondays, Tuesdays, Wednesdays, Thursdays, and Saturdays, through November 15, 2018, with a 7-day advanced purchase required.

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.

There are quite a few seasonal routes on Frontier that are ending in mid-November. There is no guarantee that seasonal routes will return next spring, so take advantage of these low fares while you can.

Tickets must be booked by 11:59 pm ET, October 5, 2018.

Keep in mind that Frontier charges extra for any bags larger than a small personal item (small backpack, large purse, etc.). Pack super light to get the lowest price. Checked bag fees start at $25-$30 each way. Larger carry-on bag fees start at $30-$35 each way.
