Save on winter travel with the current promo code sale from Frontier.
Fares are valid for domestic nonstop travel on Tuesdays, Wednesdays, Thursdays, and Saturdays through March 7 with a 3-day advance purchase. Avoid blackouts from February 15 through February 24. Along with the blackout dates, certain routes are excluded.
Enter promo code SAVE75 when booking to apply discount to the base fare. *Note that the promo code does not discount Frontier's online booking fee nor required taxes, so don't expect that large of a discount. Certain routes will still have a considerable price drop with this promo code sale.
Tickets must be booked by 11:59pm ET, January 17.
There are many more routes as well. Keep in mind, Frontier is an ultra low cost carrier and there is a charge for any baggage larger than a small personal item (backpack, purse, etc.). Travel super light and save big or add on baggage starting at $25 each way for checked baggage.
