Air France / KLM Flying Blue Program Liberalizes Expiration Policy for Miles

Frank McBride • May 29, 2026

A change in favor of airline passengers (for a change)

Airline frequent flyer programs have a range of policies addressing the expiration of their members’ frequent flyer miles.
 
In general, US carriers have the most generous policies as miles on Alaska, Delta, JetBlue, Southwest, and United
do not expire.



A second group includes American, Air Canada, Avianca, British Air, and the Air France / KLM Flying Blue program. These airlines have expirations ranging from 12 to 36 months but also offer some mechanisms for extending expirations.


Airlines in a third group including ANA, Emirates, JAL, Lufthansa, Singapore, and Turkish have “use it or lose it” hard expiration policies that do not allow for extensions (except for elite members or those willing to pay high fees).
 
While the Air France / KLM Flying Blue program falls into the second category, until recently, it had some of the less traveler friendly policies among this group. Its miles expired after 24 months. Program members could extend their expiration dates by paying for flights or making purchases on the Flying Blue co-branded credit card. However, a transfer of flexible points into your Flying Blue account would not extend the expiration date for your miles. Additionally, the miles in your account might have different expiration dates.


As of this month, the Flying Blue program will extend the expiration date on members’ miles after a simple transfer of flexible points (such as Chase Ultimate Reward or American Express Membership Rewards) into an account. Furthermore, the 24-month extension will apply to all miles in the account.


This change could not come at a better time for my household. In May of last year, Ms. Optimizer and I used Air France miles to purchase a trip to Prague. After booking this awards flight, the price for our itinerary in miles decreased by 62,000 points. Based on previous experience, these miles would be worth $1200-1500 so it was worth it to pay the change fee (140 euros or about $162 US) to recover these miles. But, of course, these 62,000 miles could only be used with Air France, and they had a two-year time limit before they expired and became worthless.
 
With the new policy, I simply transferred 1,000 American Express points to my Flying Blue account. After only a few minutes – voila – the 1,000 miles appeared in my account, and the new expiration date is now two years off.


When keeping points or miles long term (more than a year) be aware of their expiration date, if any. One of the greatest sins of the points and miles game is simply letting a “currency” expire. One thing we provide Travel Rewards Optimizer clients with is a spreadsheet template for managing their cards, points/miles, redemptions, and importantly, expiration dates of points or miles.


So many recent policy changes in the points and miles game have been about either increasing prices or taking things away from travelers. But, this change in the Air France / KLM Flying Blue program is a welcome news and will help many travelers utilize this program more efficiently.

As the summer travel season approaches, this is a friendly reminder to avoid "dynamic currency conversion" (DCC) when making credit card purchases outside of your home country. DCC gives you the option of selecting a payment amount in your home currency rather than in the local currency. Typically, when presented with a credit card reader at a shop or restaurant, the touch screen will show purchase amounts in the local currency and in US dollars (for those with American credit cards) and you have the opportunity to choose. I have been seeing these “offers” for several years now and have learned, after doing a little mental math, they are almost always a bad deal for the purchaser. When presented with a credit card reader, I always choose to pay the amount shown in local currency rather than the amount shown in US dollars. During a recent trip, I was making purchases in Euros, Hungarian Forints, and Czech Korunas. From what I could tell, the option of paying in dollars inflated the cost of the purchases around an average of five percent (5%). Once, a card reader screen acknowledged that making the purchase in dollars added an eight percent (8%) fee. Even a credit card with a foreign transaction fee (which you should avoid using when traveling abroad) would have added only three percent (3%) to the tab. Currency games aside, Visa and MasterCard offer reasonable exchange rates when you choose to pay in the local currency. Upon returning home, our credit card statements showed exchange rates that were quite close to market rates. It is reasonable and fair for the credit card issuers make a fraction of a percent here and there as they are performing a service and accepting currency risk (although very briefly). But, claiming to offer a “preferential” rate to pad their bottom line is disingenuous. Because exchange rates are reasonable, using credit cards while traveling abroad is still worthwhile for a points and miles program as long as you avoid cards with foreign transaction fees. Travel oriented cards can offer 2X and 3X spending bonuses for transportation and restaurants to give you a leg up on saving money and accumulating points or miles for your next vacation.

I have read a great deal recently about crowding at airport lounges or even lengthy waits to get into lounges. Hartsfield-Jackson Atlanta International Airport, dominated by Delta Airlines, has eight Delta Sky Clubs (there is one in each of the airport’s seven concourses except for Concourse A which has two). Even with the wide availability of Sky Club options, many of the Atlanta locations still get crowded and can have long lines of travelers waiting to get in. Despite flying Delta through Atlanta many times in the past couple of months, Ms. Optimizer and I have avoided this problem. We have used the Fly Delta app to keep us apprised of which Sky Clubs are crowded, and which are relatively empty. Although we might prefer a Sky Club near the gate we will use for our next flight, we often use a Sky Club on an adjacent concourse if the Sky Club closest to our gate is crowded or has a line. The Atlanta International Airport has a straightforward configuration of parallel concourses starting with Concourse T, followed by Concourses A through F. These seven concourses are connected by the Plane Train. The Plane Train can transport you between adjacent concourses in about a minute. Or, if you want to get in some steps, you can walk to an adjacent concourse in about five minutes (less if you use the moving sidewalk). The walkways are below ground level and can be accessed where you get on the Plane Train. The Fly Delta app is easy to use for assessing Sky Club capacity. When you arrive in Atlanta, go to the Delta Sky Club tab (it has a cocktail glass icon) and open. It will open to a list of the Atlanta Sky Clubs and describe their status ranging from “extremely busy” to “not busy.” Even if you can get into an “extremely” busy Club, bear in might that you might be the last person who brings the Club to full capacity. We have found that a short walk to the next concourse is well worth it as a less busy club offers a better choice of seating and a more relaxed atmosphere (and less likelihood of lines at the buffet, bar, coffee machine, etc.). But, don’t forget to budget enough time to return to the concourse with your departure gate!! We are ready to help you turn your routine credit card spending into the travel of your dreams.
