Frontier Airlines, the Denver-based low-cost carrier, is offering some super-cheap fares. They start at $29 one-way, but you’ll need to book quickly to lock in this deal.

The latest flash sale offers cheap flights across the U.S., the Caribbean, and Latin America — for those who move fast, anyway. You’ll need to book by October 6, 2025, and travel by February 28, 2026.

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

Sample Fare

To benefit from this promotion, customers can book travel at FlyFrontier.com or the Frontier mobile app (iOS, Android) by October 6, 2025. A 14-day advance purchase is required to qualify for the promotion.

We even found fares lower than the advertised $29 round-trip price — like an Atlanta (ATL) to Orlando (MCO) flight for just $16 for Discount Den members — showing how much value you can score when you book early.

When you calculate your Frontier airfare for this promotion, keep in mind that certain services, such as checked baggage and priority boarding, are not included in the base rate and will incur additional fees. Many of those can be avoided by having elite status with Frontier, though.

Final Thoughts

Frontier Airlines is offering one-way flights from $29 (and even lower) if you book soon. You’ll need to book by October 6 and travel by February 28, 2026. Not all routes are available for $29, though. The cheapest prices will be available on short flights and for those with a Discount Den membership.

If you’re flying further and don’t travel with Frontier often enough to justify paying for a Discount Den plan, it’s worth checking Frontier’s price against what other airlines are charging since this sale might not be your best option.
