American Express has rolled out a new targeted Amex Offers deal aimed at Frontier Airlines: spend $200 or more with the ultra low cost carrier and get a $50 statement credit. That works out to as much as 25% back if you hit the threshold exactly, which is a solid discount on an airline that's already among the cheapest in the US.

The offer covers purchases made directly with Frontier — either on flyfrontier.com or through the airline's app — through the end of 2026. You can hit the $200 spend in one go or across multiple transactions, and it applies to more than just base fares: in-flight purchases, baggage fees, pet fees, cancellation and change fees, and business or group bookings all count. Just note the charge needs to post by 31 December 2026; you don't have to actually fly by then.

There are a few catches. Flight purchases must originate in the United States and be charged in US dollars. The deal excludes anything booked through third parties, plus add-ons like travel insurance, car rentals, hotels, transfers, tours, and gift vouchers. Since it's a targeted offer, you'll need to check your Amex account to see whether it's been loaded to your card.

One clever angle worth considering: Frontier has scrapped change fees on many of its fare bundles (Economy, Premium and Business Bundles among them), so you could book a $200-plus ticket now, bank the statement credit, and if plans shift, convert the balance into a Frontier flight credit that stays valid for 12 months. In other words, you can lock in the discount even without a firm trip in mind.

To squeeze out maximum value, check whether the offer can be added to an Amex card that earns bonus points on airfare. That way you're stacking the $50 credit with rewards points on top of an already cheap fare.

Deals like this are a good reminder to scroll through your Amex Offers menu before booking anything — targeted savings pop up regularly on airlines, hotels and car hire, and they're easy to miss. If you fly Frontier or any US budget carrier even occasionally, a free $50 off makes a bare-bones fare considerably more palatable.
