The Amex Membership Rewards program has just introduced its latest transfer bonus, as you can earn a 25% bonus when moving points to Air France-KLM Flying Blue. Personally I find this to be an excellent offer, and it’s one I’d take advantage of if I hadn’t speculatively moved over a bunch of points between programs earlier this year.

Between October 1 and October 31, 2026, you can receive a 25% bonus when you transfer Amex Membership Rewards points to Air France-KLM Flying Blue.

This promotion is being offered on Amex’s end (in the United States), and is hard coded into the transfer ratio, meaning you should see the bonus at the time that you make the transfer. You can take advantage of this offer an unlimited number of times, though you’re limited to transferring 999,999 points per transaction (not that this is a limit that will impact many people).

There are lots of fantastic cards for earning Amex Membership Rewards points , so this is an awesome opportunity. Transfers from Amex to Flying Blue are generally instant . We typically see a transfer bonus from Amex to Flying Blue once or twice per year, and 25% is as good as bonuses get. We last saw a 25% transfer bonus between the programs in June 2026.

Air France-KLM Flying Blue is a valuable SkyTeam frequent flyer program . The program has attractive award pricing on Air France and KLM, offering many of the best ways to cross the Atlantic. Admittedly saver award availability can be tough to come by , though if you have Flying Blue Platinum status , you get access to more award space , which is an awesome perk.

On top of that, Air France and KLM make more award seats available to members of the Flying Blue program than to members of partner programs. So even when Flying Blue’s pricing isn’t the best, there are situations where it could make sense to book through Flying Blue (though with all of the Delta SkyMiles devaluations we’ve seen , typically you will find the best pricing through Flying Blue).

I should mention that in September 2026 we saw a Flying Blue devaluation , whereby awards now followed a tiered pricing structure. This means that the cheapest awards are now “Light” fares, and if you want the same inclusions as before, you need to buy up to a “Standard” fare, which costs more miles.

There’s always value in having a stash of Flying Blue miles if you think you’ll be traveling transatlantic in the coming months. I redeem through Flying Blue every year (usually multiple times per year), and consistently get value. I find it to be one of the most useful frequent flyer programs for redeeming points.
