Book fast! Frontier is having a promo code sale valid for purchase today only! Save 75% off the base fare for travel through June 6. Fares start at just $37 round-trip.
Use promo code SAVE75 when booking on FlyFrontier.com to take 75% off the base fare for nonstop domestic flights. Travel is valid on Mondays, Tuesdays, Wednesdays, Thursdays, Fridays, and Saturdays, starting May 11, through June 6. Avoid blackout dates May 24-28.
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 75% off. However, there are plenty of routes where we are seeing very large discounts so you may be able to save big depending on your route/dates.
There is a long list of specific routes excluded from the promo code sale. Frontier operates about half of their markets on a limited and/or seasonal basis, so be sure to check out the fare details for specifics.
Tickets must be booked by 11:59 p.m. ET, tonight, May 7.

Keep in mind that Frontier charges extra for any bags larger than a small personal item (small backpack, briefcase, 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.
