[Expired] Frontier Airlines Flash Sale: 100% Off Base Fare [Ends Nov. 20]

Frontier Airlines, the low-cost carrier based in Denver, has returned with one of its most impressive sales of the year, offering significant savings on your next flight.

Here’s what you need to know to save big on your next Frontier flight!

Save 100% When Using Promo Code SAVE100

Frontier Airlines is celebrating Thanksgiving early with a special “Thank You Sale” that offers up to 100% off base fares for a limited time.

Until November 20, 2024, at 11.59 p.m. ET, passengers can use the discount code SAVE100 to save 100% off base fares for travel on Tuesdays, Wednesdays, and Saturdays through February 26, 2025. If flying on those days is not an option, you can save 50% off base fares for travel on Mondays and Thursdays instead.

The following blackout dates apply: November 26-27, 30, 2024; December 1-2, 21-31, 2024; January 1-7, 2025; and February 13-14, 16-17, 2025.

To score these steep discounts, a round-trip purchase is required, and the fare must be purchased 7 days in advance.

With a travel window that extends until the end of February, this sale could be a significant savings opportunity if you’re hoping to escape the brutally cold winter for somewhere warmer. However, as you can see here, many routes are excluded from this discount.

“We are beyond thankful to our customers for their continued support and want to express our appreciation this Thanksgiving season,” said Tyri Squyres, vice president of marketing at Frontier Airlines. “Now is a great time to finalize winter travel plans and take advantage of this exceptional sale.” 

Sample Fares

Use the promo code SAVE100 when booking to secure the best deals available. We conducted several searches, including this flight from Denver (DEN) to Phoenix (PHX), leaving on a Wednesday and returning 3 days later on a Saturday. The total amounted to $57 for a round-trip, excluding any fees for bags or additional purchases.

If you’re looking for an escape from the cold weather on Long Island, consider flying to South Florida. In February, this sale allows you to fly from Long Island (ISP) to West Palm Beach (PBI) for just $63.

When you calculate your Frontier airfare, keep in mind that certain services, such as checking baggage and seat selection, are not included in the base rate and will incur additional fees. Some of the cheapest fares are exclusively accessible to Discount Den members.

Final Thoughts

Frontier runs sales like this one rather frequently. If the routes and dates work for your trip plans, you can get 100% off the base fare for bookings made before November 20, 2024, at 11:59 p.m. You will still have to pay for items like seat assignments and carry-on luggage, but if you spot an offer you like, act quickly before it disappears.
