Starting May 4, Flying Blue is moving to a single expiration rule for all miles. Previously, miles earned from flights and miles earned from partners had different expiration timelines. That created a confusing mess of dates to track.
Flying Blue is the loyalty program for Air France, KLM, and other SkyTeam alliance partners. It has long been one of the more valuable programs for travelers heading to Europe. The main reason is the rotating Promo Awards. These can drop transatlantic redemptions to as low as 15,000 miles one way. The program has four status tiers — Explorer, Silver, Gold, and Platinum. Miles can be earned through flights, credit card transfers, and a wide network of non-airline partners.
The catch has always been managing expiration. Flying Blue had a two-tier system that required you to track which miles were expiring and why. That system is going away. Starting May 4, one rule covers everything.
How the New Rule Works
Any qualifying activity will now reset your entire balance and extend all miles by 24 months. That includes booking a flight, reserving a hotel, renting a car, or shopping with a Flying Blue partner.
This also applies to miles you already have. If your balance had different expiration dates, Flying Blue will automatically apply the most favorable one. No action needed.
The key points:
- One unified 24-month validity for all miles
- Any qualifying activity resets the full balance
- Existing miles are automatically updated
- Most favorable date applies to pre-existing balances
What resets flying blue miles expiration date?
These activities reset the expiration on all your miles for two years, regardless of how you earned them. Qualifying actions include:
- Flying with Air France, KLM, or a SkyTeam partner like Delta or Kenya Airways
- Making a purchase with a Flying Blue co-branded credit card
- Holding Flying Blue Silver, Gold, Platinum, or Ultimate status
For U.S. travelers the easiest move is crediting a Delta flight to Flying Blue. Delta is a SkyTeam partner. Any Delta flight credited to your Flying Blue account counts as a qualifying activity. It doesn’t need to be a transatlantic flight. A short domestic hop works just as well. All your miles get two more years from that date.
If you don’t have a Delta flight coming up, buying miles also resets the clock. It is not the most efficient use of money. But if you are sitting on a large balance that is about to expire, it can be worth it. You can see how Flying Blue compares to other programs in the European Airlines section of our expiration policy guide.
Our Take
The old system had a trap that caught a lot of people off guard. Flying Blue treated flight miles and partner miles separately. A hotel booking could only extend the partner-earned portion of your balance. It had no effect on flight miles. And if you credited a flight to an account that held transfer miles — from Amex Membership Rewards or Chase Ultimate Rewards — all of those miles got reclassified as “flight miles.” Once that happened, you were stuck relying on flying or a co-branded card to keep them alive.
That’s gone now. One qualifying activity covers your entire balance, regardless of how those miles were earned. This is a much needed change and a welcome one. Flying Blue miles can be very useful if you can take advantage of their promo awards. The simplified expiration policy makes it easier to keep a balance alive without babysitting it.
If you have miles sitting dormant, now is a good time to log in and check where things stand. You may have more runway than you think. And if you want to see how other programs handle expiration, we have a full breakdown of airline miles expiration policies across every major program.
