The latest promo code sale from Frontier allows you to take 50% off the base fare for travel through October 3. Fares start at just $53 roundtrip.
Use promo code SAVE50 when booking on FlyFrontier.com to take 50% off the base fare for nonstop domestic flights. Travel is valid on Tuesdays and Wednesdays, from July 3 through August 15, and Mondays, Tuesdays, Wednesdays, Thursdays, and Saturdays, from August 16 through October 3. Avoid the lone blackout date on September 3.
The discount does not apply to taxes nor Frontier's online booking fee, which they label 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% off. However, there are plenty of routes where we are seeing decent discounts.
There is a long list of specific routes excluded from the promo code sale. Some routes are only excluded for summer travel, while others are only excluded for fall travel. Frontier operates about half of the route network just a few days each week, so you may have to click around to find available travel dates. Click on the fare details for more info on exact dates each route is available.
Tickets must be booked by 11:59pm ET, on June 29.
A sample of nonstop fares include:
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.
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 each way. Larger carry-on bag fees start at $30 each way.
