[Expired] Get a 20% Bonus When You Transfer Citi Points to Air France-KLM Flying Blue

Utilizing transfer bonuses is a great way to extract even more value from your hard-earned points and miles. Right now, Citi ThankYou Rewards is offering an attractive 20% transfer bonus when transferring points to Flying Blue, the highly regarded frequent flyer program of Air France and KLM.

Let’s take a look at the details and see if this transfer bonus is worth taking advantage of.

New Limited-Time Transfer Bonus Through August 22

Usually, Citi ThankYou Rewards Points transfer to Air France-KLM Flying Blue at a 1:1 ratio. However, you’ll now get 1,200 miles when you transfer at least 1,000 ThankYou Points to Flying Blue, bringing the transfer ratio to 1:1:2. This means that for every 1,000 ThankYou Points transferred, you’ll yield 1,200 Flying Blue miles.

This bonus is valid from July 19 to August 22, 2026. No registration is required to take advantage of this promotion, and the bonus points will be reflected in your Flying Blue account as soon as the transfer is completed.

In our experience, transfers between Citi and Flying Blue happen instantly, though note they can take a couple of days to complete in some instances.

Is It Worth It?

We’ve found that using the Flying Blue program is a particularly great way to get between the U.S. and Europe, as you can find business class seats starting at just 55,000 miles one-way, and availability tends to be decent.

The program offers Promo Rewards each month, which become even more attractive when there’s an ongoing transfer bonus. While a 20% transfer bonus isn’t the highest we’ve ever seen for Flying Blue, it’s fairly rare to see transfer bonuses from Citi to Flying Blue, which makes the current one something to very seriously consider if you’ve got travel plans on the mind and have some ThankYou Points to use.

If you still want to earn Air France-KLM Flying Blue miles after taking advantage of this Citi transfer bonus, remember that all of the other major currencies — American Express Membership Rewards, Bilt Rewards, Capital One Miles, Chase Ultimate Rewards, and Wells Fargo Rewards — also transfer to Flying Blue.

Final Thoughts

There’s a new 20% transfer bonus from Citi to Air France-KLM Flying Blue. Transfer bonuses don’t happen very frequently between these 2 programs. The last time we saw a transfer bonus from Citi to Flying Blue was a year ago, so this represents a great opportunity to squeeze even more value out of your Citi ThankYou Points.
