Book quickly! Frontier just released a promo code sale for today only!

Use promo code SAVE90 when booking on to take 90% off the base fare for nonstop domestic travel on the following dates: January 27, 30, 31; February 1, 3, 6, 7, 10, 13, 14, 21, 22, 27, 28; and March 6, 2018. Can't fly those dates? You can also use promo code SAVE15 for a 15% discount any day of the week between January 27 - March 7.

The discount does not apply to Frontier's online booking fee nor taxes, which 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 90% off promo code. They also operate on a limited basis in some markets, so be sure to check out the fare details for specifics.

Tickets must be booked by 11:59 p.m. tonight, January 24.

Nonstop fares include:

Charlotte to Orlando $48 round-trip

Denver to Las Vegas $50 round-trip
