If you have plans to travel with Frontier Airlines this summer, you could earn up to 20,000 bonus miles on your flights.

The airline is offering 5,000 bonus miles for each eligible round-trip you complete through August 31, 2026 — up to 4 round-trips total.

Here are the details of Frontier’s latest promotion.

Frontier 20,000 Bonus Miles Promotion Details

Frontier Airlines‘ latest promotion offers Frontier Miles members a chance to earn 5,000 bonus miles for every eligible round trip completed through August 31, 2026 — up to a maximum of 20,000 bonus miles.

You must register for this promotion on this webpage, and you have until May 31, 2026, to do so.

Each 5,000-mile bonus will be deposited into your Frontier Miles account within 3 business days after completing an eligible round trip during the promotional period. Only flights booked directly with Frontier Airlines are eligible.

Keep in mind that GoWild fares, award tickets, charter flights, group bookings, and free tickets do not qualify for this promotion.

Is It Worth It?

We value Frontier Miles at 1.1 cents each. That means 5,000 miles are worth $55. That’s decent value from a low-cost airline. While maxing out the promotion with 20,000 bonus miles could net you about $220 in value.

Redemptions with Frontier Airlines miles start at 5,000 miles and go up from there, so this bonus alone could help you redeem Frontier Airlines miles for a flight. That said, remember that you pay a fee between $15 and $75 when redeeming miles, unless you have elite status with Frontier. That redemption fee diminishes the value of your miles.

Taking all of that into account, it’s probably not worth going out of your way to book a trip just for the sake of these 5,000 bonus miles. However, if you were already planning travel with Frontier Airlines, this promotion could feel like a gold mine.

Final Thoughts

Frontier Airlines is offering qualifying members the chance to earn up to 20,000 bonus Frontier Miles this summer by registering by May 31 and completing eligible round-trip flights through August 31, 2026.

While it’s probably not worth planning extra travel just to earn the bonus, this promotion could provide a nice boost for anyone already flying Frontier over the next few months.
