Frontier Airlines, the Denver-based low-cost carrier, is offering some super-cheap fares. They start at $29 one-way, but you can drop that price down to just $19 with a Discount Den membership, and 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 January 22 and travel by April 13, 2026.

This sale originally required booking by January 8, but it’s now been extended a second time. Here’s what you need to know to save big on your next Frontier flight.

When calculating your Frontier airfare for this promotion, note 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, with even lower prices available to Discount Den members. However, bookings must be made by January 22, and travel must occur by April 13, 2026. Not all routes are available for $29, though. The lowest prices will be available on short flights and for Discount Den members.

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.
