Amex Points to Flying Blue: Grab a 25% Transfer Bonus Before October 31

If you've been sitting on a pile of Amex Membership Rewards points, there's a new transfer bonus that might make your next trip a lot cheaper. American Express is giving 25% extra miles when you move points to Air France/KLM Flying Blue, and the timing lines up nicely with some discounted award rates. But before you rush to transfer, there are a few things you should know.

Why This Transfer Bonus Is Worth a Look

A 25% bonus is nothing to sneeze at, especially when it stacks with Flying Blue's Promo Rewards. Right now, you can book economy awards from many US cities to Europe for 18,750 miles one-way. With the bonus, that drops to just 15,000 Amex points per person. That's a fantastic deal for a transatlantic flight.

Even without Promo Rewards, the bonus can take the sting out of standard business class awards. A typical business class ticket from the US to Europe costs 60,000 Flying Blue miles. With the 25% bonus, you'd only need to transfer 48,000 Amex points. That's a solid redemption, especially if you can find availability.

Where Flying Blue Miles Shine

Flying Blue is the loyalty program for Air France and KLM, but you can also use miles on SkyTeam partners like Delta. Some of the sweet spots include:

One thing to keep in mind: Flying Blue often adds fuel surcharges and taxes to award tickets, so your "free" flight might come with a few hundred dollars in fees. Always check the total cost before transferring.

• Promo Rewards: Each month, Air France discounts award rates on select routes. Economy flights from the US to Europe can sometimes be had for less than 11,000 miles one-way.
• Israel for the same price as Europe: You might find business class from the US to Tel Aviv for as low as 60,000 miles one-way.
• Delta flights to Hawaii: Economy awards between the US and Hawaii start at 17,500 miles one-way. First class is also available, but Delta rarely releases that space.

The Catch: Availability and Fees

Flying Blue is known for having decent award availability, but it's not always guaranteed. Before you transfer any points, log into your Flying Blue account and search for the exact flights you want. If you don't see the award space, don't transfer. Amex points are valuable and flexible; once they're in Flying Blue, they're stuck there.

Also, remember that Flying Blue miles expire after two years of inactivity. Transferring points into your account counts as activity and resets the clock, so that's an easy way to keep your miles alive. But if you're not planning to use them soon, you might want to hold off.

Should You Transfer Now?

If you've already found a Flying Blue award that works for you, this 25% bonus is a no-brainer. It's a limited-time offer that ends October 31, 2026, so you'll want to act before then. But if you're just speculatively transferring, think twice. Award space can be elusive, and you don't want to be stuck with miles you can't use.

As always, do the math and compare your options. Sometimes transferring to a different partner or booking through Amex Travel might make more sense. But for the right trip, this bonus can save you a bundle.

Bottom Line

• 25% transfer bonus from Amex Membership Rewards to Flying Blue ends October 31, 2026.
• Stack with Promo Rewards for economy flights from 15,000 Amex points one-way to Europe.
• Business class to Europe can require just 48,000 Amex points with the bonus.
• Watch out for high taxes and fees on Flying Blue awards.
• Only transfer if you've confirmed award availability for your desired flights.
