Book fast! Frontier is having a promo code sale valid for purchase through today. Save 75% off the base fare for travel through May 23. Fares start at just $39 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, and Saturdays, from April 24 through May 23.
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.
There is a long list of specific routes excluded from the promo code sale. Frontier operates about half of their markets on limited days each week. Click on the fare details for more info.
Tickets must be booked by 11:59pm ET, on April 23.
