ST. LOUIS — Frontier Airlines is offering a flash sale Tuesday through which you can get 100% off base fares for travel to many destinations.

This is part of the low-cost airline’s early Black Friday promotions. Just use the code SAVE100 when booking on FlyFrontier.com.

Now is a good time to plan your winter travel while taking advantage of this one-day deal, KTVI reports.

The sale is for travel between Nov. 29, 2023, and March 6, 2024, with travel days on Mondays through Thursdays and Saturdays. But you have to book by 11:59 p.m. ET on Tuesday, Nov. 14.

You also must book a round trip to get the discount — which applies to both domestic and international flights — and it may only be applied to the base fare, not taxes and fees.

Some routes have restrictions and blackout dates. Here are the blackout dates for the deal: Dec. 15-31, 2023; Jan. 1-8 and 16, 2024; Feb. 8-12, 19 and 22-23, 2024, and March 2, 2024. Certain route exclusions apply. Got to Frontier’s website for more details.
