Citi ThankYou Points now transfer to Flying Blue with a 20% bonus through August 22, 2026. That means 1,000 ThankYou points become 1,200 Flying Blue miles.

The bonus is useful only when you have already found an award you can book. Points transfers are final, and Flying Blue availability can disappear before the miles arrive. Flying Blue says transfers generally post instantly but can take up to 15 days. Confirm the offer terms and transfer timing with Flying Blue before you move points.

The quick decision

Transfer now if all three are true:

  • You have a specific Flying Blue award available.
  • The 20% bonus reduces the points you need enough to make that award better than your alternatives.
  • You can accept the risk that the award seat may disappear before the transfer completes.

Wait if you are transferring only because the bonus exists. A 20% bonus does not fix poor award pricing, carrier surcharges, or an itinerary you would not otherwise book.

When Flying Blue can be a strong use of Citi points

Flying Blue can be compelling when its price and availability beat other programs for the exact flight you want, especially for Air France, KLM, and selected partner itineraries. The right comparison is not “is 20% a large bonus?” It is “does this transfer let me book this seat for fewer Citi points than the next-best bookable option?”

If the answer is yes, the bonus creates real value. If you are still comparing cards or building a ThankYou balance, start with the Citi Strata Premier card details and keep the points flexible until you have a trip in mind.

Check these before you transfer

  1. Search the itinerary first and confirm the cabin, dates, taxes, and fees.
  2. Confirm the mileage price in Flying Blue, not just a third-party estimate.
  3. Calculate the Citi points required after the 20% bonus.
  4. Check whether another transferable currency or airline program gives you a better result.
  5. Transfer only the amount needed for the booking, plus a small cushion only if the program requires it.

Usually no. The transfer cannot be reversed, and award availability can change. The safer move is to find the flight first, then transfer the exact number of points needed.

Bottom line

This is a good bonus for a confirmed Flying Blue redemption, not a reason to speculate. Find the award first, compare the total cost against alternatives, then use the bonus to reduce the Citi points required.
