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.
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.
Key terms
- Registration is required by 11:59 p.m. MT on May 31, 2026.
- All eligible flights must be completed by 11:59 p.m. MT on August 31, 2026.
- GoWild fares, award tickets, group bookings, charter flights, specially negotiated fares, and free tickets are not eligible for this promotion and won't count toward qualifying round-trip totals.
- If bookings are changed, canceled, or otherwise not flown, applicable bonus miles won't be awarded.
- The bonus miles earned through this offer are not Elite Status Points and won't count toward elite status qualification.

Sign up for Discount Den, Pay No Enrollment Fee
If you're not familiar with Frontier Discount Den, it's a membership program that lets you pay to unlock certain benefits. It's not elite status, per se, but for $59.99 per year, you can access lower fares, Kids Fly Free days, and more.
Ordinarily, the program costs $59.99 for the first year plus a $50 enrollment fee. But through May 15, 2026, that enrollment fee has been waived. Click here to enroll — and if you need a referral code, here's mine: 90090160851.
Even if you only fly Frontier Airlines a couple of times a year, you can still come out ahead with a Discount Den membership. Better yet, Discount Den fares count toward the bonus points promotion above, meaning you could pay less for your flights, earn a pile of bonus miles, and then have rewards ready for future award travel.
Our Take
Frontier Airlines is making a play to become your low-cost carrier of choice. At the time of writing, you can register to earn up to 20,000 bonus miles through the airline's new “Fly One, Get One” promotion, and you can enroll in Frontier Discount Den without paying the usual first-year enrollment fee.
If you see yourself flying Frontier in the year ahead, don't forget to register and lock in your savings before these offers fly away.
