Nationwide promo code sale on Frontier. Save 50% off the base fare for spring travel. Fares start at just $53 round-trip.

Use promo code SAVE50 when booking on to take 50% off the base fare for nonstop domestic flights. Travel is valid on Mondays, Tuesdays, Wednesdays, Thursdays, Fridays, and Saturdays from April 9 through May 23. We don't normally see Fridays included in these promo code sales. If you are unable to fly in the middle of the week, this sale may help you out.

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 be discounted a whole lot, but there is the potential to save big on certain travel days or routes. As always with Frontier, there are many specific routes excluded from the promo code sale. They also operate on a limited basis in many markets, so be sure to check out the fare details for specifics.

Tickets must be booked by 11:59 pm ET on February 23.
