Citi ThankYou Points to Flying Blue: A 20% Transfer Bonus Worth Considering

If you've got a stash of Citi ThankYou points and you're dreaming of a trip to Europe (or even just a quick domestic Delta flight), here's a deal that might make those miles go a little further. From now until August 22, 2026, you can get a 20% bonus when you transfer your ThankYou points to Air France KLM Flying Blue. That's a solid bump, especially if you've been eyeing a business class seat across the Atlantic.

How the Bonus Works

It's pretty straightforward. You log into your Citi ThankYou account, head to the transfer section, and choose Flying Blue as your partner. Normally, 1,000 ThankYou points would get you 1,000 Flying Blue miles. But during this promotion, that same 1,000 points turns into 1,200 miles. The bonus is automatic—no codes or extra steps needed.

Just keep in mind that this offer is only available to folks holding the Citi Strata Elite, Citi Strata Premier, or the older AT&T Access More card. If you have a different Citi card, you might not see the bonus option.

Where Flying Blue Miles Shine

Flying Blue is the loyalty program for both Air France and KLM, and it's one of the more useful programs for getting to Europe. Business class awards from the US to Europe start at 60,000 miles each way. But here's the thing—Flying Blue regularly runs promo rewards where you can snag business class for as low as 45,000 miles, and economy for 18,750 miles. With this 20% bonus, those promo rates become even sweeter: you could book a business class seat for just 37,500 ThankYou points, or an economy ticket for 15,625 points.

Now, a word of caution: Flying Blue passes along fuel surcharges and fees. On business class awards, expect to pay around $300 to $400 each way in taxes. That's not cheap, but if you're flexible and can find those promo rates, the overall value is still strong.

Another hidden gem: Flying Blue miles can also be used to book Delta flights within the US. For short hops, you can sometimes find awards starting at just 5,000 miles. Just be aware that Delta recently cut off partner award access within 21 days of departure, so you'll need to plan ahead.

A Perk for Families

If you're traveling with kids, this is a big one. Flying Blue offers a 25% discount on award tickets for children aged 2 to 11 on long-haul flights. That applies to any cabin—economy, premium economy, or business. So if you're a family of four, that can add up to serious savings. Combine that with the transfer bonus, and you're looking at a really compelling deal for a family trip to Europe.

Bottom Line

• Transfer bonus runs through August 22, 2026—don't wait too long.
• Best value is on Flying Blue promo rewards to Europe, especially in business class.
• Factor in $300–$400 in surcharges for business class awards.
• Kids ages 2–11 get a 25% discount on long-haul awards—great for families.
• Flying Blue miles work for Delta domestic flights, but book early.
