Book quickly! Frontier has a great promo code sale that ends tonight! Take up to 90% off the base fare for travel this fall and 50% off the base fare for winter travel. Fares start at just $33 roundtrip.
Use promo code SAVE90 when booking on FlyFrontier.com to take 90% off the base fare for nonstop domestic flights on Tuesdays and Wednesdays, through December 18, 2018, with a 7-day advanced purchase required. Blackout dates apply: November 17-27. For winter travel, use promo code SAVE50 to take 50% off the base fare travel on Tuesdays and Wednesdays, from January 8 - March 6, 2019. There is one lone blackout date on February 19.
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 50-90% off. However, there are plenty of routes where we are seeing deep discounts. 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 route exclusions for both the 90% off and the 50% off promo code sales. 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.

Tickets must be booked by 11:59 pm ET, October 1, 2018.

Many more routes are available and these fares all work in reverse as well. Lowest fares may not be available throughout the entire travel period. You'll have to decline all extras to get the lowest price.
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.
