Take up to 90% off your next Frontier flight for travel through mid-December. Fares start at just $45 roundtrip.
Although these promo code sales have been popping up fairly often lately, this is a rare promo code sale that includes discounted travel on Sundays and Fridays.
Use promo code AUTUMN when booking on FlyFrontier.com to take 90% off the base fare for nonstop domestic flights on Tuesdays, Wednesdays, Thursdays, and Saturdays, through December 15, 2018. Travel on Sundays, Mondays, and Fridays, may also be discounted 35% off. An advanced purchase of 3-days is required and blackout dates apply November 12, and 17-27, 2018.
The discount does not apply to taxes nor Frontier's online booking fee, which is labeled a "Carrier Interface Charge". This means some routes still won't have a very big price drop even with the big sticker shock of 90% off. However, there are plenty of routes where we are seeing some big price drops. The discount can also be applied to one-way flights.

A sample of nonstop fares include:
These fares all work in reverse and there are many more routes available as well. Lowest fares may not be available throughout the entire travel period. You'll have to decline all extras to get the lowest price.
Keep in mind that Frontier charges extra for any bags larger than a small personal item (small backpack, large purse, etc.). Pack super light to get the lowest price. Checked bag fees start at $25-$30 each way. Larger carry-on bag fees start at $30-$35 each way.
