90% off Promo Code Sale on Frontier for Fall/Winter Travel from $33+ Roundtrip

Frontier is having another high percentage promo code discount for purchase today or tomorrow. Save up to 90% off the base fare on your next Frontier flight for late fall or winter travel. More dates are included in this week's sale compared to last week. Fares start at just $33 roundtrip.

Use promo code SAVE90 when booking on FlyFrontier.com to take 90% off the base fare for nonstop domestic flights on the following dates: 

November: 14, 28-30

December: 1, 3-6, 8, 11-12, 15

January: 8-9, 12, 15-16, 19, 22-23, 26, 29-30

February: 2, 5-6

While the promo code does not apply to taxes nor Frontier's online booking fee, which is labeled a "Carrier Interface Charge", the fact that it does take 90% off the base fare means that these are the some of the lowest fares we ever see on many routes. Occasionally, Frontier has lower fares with flash sales on less popular routes when it eliminates or lowers the online booking fee, but the most popular routes rarely dip this low. The discount can also be applied to one-way flights.

If you are unfamiliar with Frontier Airlines, please read our guide on Everything You Need to Know Before You Fly Frontier.

There are specific routes excluded from this promo code sale. You may have to click around to find available dates since Frontier operates about half its route network on just a few days each week, and the schedule can change from month to month. Click on the fare details for more info on exact dates each route is available.

Tickets must be booked by 11:59 pm ET, November 13, 2018.

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 $30 each way. Larger carry-on bag fees start at $35 each way.

If you want to avoid all extra fees, read How to Pack in Just a Personal Item Sized Bag.

As an example booking, after entering promo code SAVE90 on FlyFrontier.com, I found seats departing New York LGA on Saturday, January 26, returning from Miami MIA on Tuesday, January 29, for $70 roundtrip. Perfect for a winter weekend getaway.
