Bonus miles are great, and Frontier Airlines just launched a new promotion that can help you earn up to 20,000 of them. With this offer, you can effectively earn enough miles for a one-way flight after completing just one round-trip.

Here's what to know about Frontier's “Fly One, Get One” promotion and how to register. Plus, we'll introduce another offer that can help you unlock these bonus miles for even less.

[Booking Window Closed] Register to Earn up to 20,000 Bonus Frontier Miles

This new Frontier Airlines promotion is super simple. After registering your Frontier Miles account by May 31, 2026, you'll earn 5,000 bonus miles for each round-trip you fly by August 31, 2026. The cap on this offer is 20,000 bonus miles, which equates to four round-trips.

Award flights on Frontier start at just 5,000 miles, so the bonus from completing a single round-trip is enough for a one-way award flight. That's a pretty solid offer, especially if you don't mind flying Frontier.

For the purposes of this promotion, only paid fares count. So, you can't redeem Frontier Miles for an award flight and also earn toward the 5,000-mile bonus threshold.
