After launching a less-than-impressive 20% transfer bonus to Marriott yesterday, American Express has added a second transfer bonus this month which will be a lot more enticing. Through June 30, you can get a 25% bonus when transferring Membership Rewards points to Air France/KLM Flying Blue.

The Deal
- American Express is offering a 25% transfer bonus to Air France/KLM Flying Blue.
Key Terms
- Expires June 30, 2026.
Quick Thoughts
Flying Blue launched a new set of Promo Rewards yesterday which gives an opportunity to book economy awards between many US cities and Europe for 18,750 miles one way. With this 25% transfer bonus, you’d only need to transfer 15,000 Membership Rewards points per person.
If you can find business class awards at standard pricing between the US and Europe, the 60,000 miles you’ll need per person would only require 48,000 Membership Rewards points to be transferred. While 60K business class awards can be pretty hard to come by with Flying Blue, there is a surprising amount of availability out of New York from January to March 2027 right now to some cities.
Bear in mind that Flying Blue awards come with somewhat high taxes and fees. You might be able to mitigate some of that impact if you’re targeted for this Amex Offer that awards 20,000 bonus Membership Rewards points when spending $1,000. Note that the Amex Offer is only valid for flights departing the US, so it’s not helpful for one way awards departing Europe.
