Several weeks back, the Air France-KLM Flying Blue program revealed intentions to enhance its mileage expiration policy, a change that will certainly be welcomed by most members. This update is now in effect, so members should expect to see their accounts accurately reflecting this modification.
## Flying Blue revises 24-month mileage expiration policy
Before today (up until May 3, 2026), the mileage expiration policy for Air France-KLM Flying Blue was as follows:
– Miles would expire after 24 months of inactivity (though this rule did not apply to Flying Blue elite members, as long as they retained their status)
– Only certain actions could reset the expiration of miles, such as crediting a flight to the program or earning miles through a co-branded card
– Other methods of earning miles, like transferring points from a transferable currency, would not reset the miles’ expiration
This policy has recently changed. Effective today (May 4, 2026), Flying Blue will apply the same 24-month mileage expiration policy to all accrued miles. In other terms, all miles share a single expiration date, and any activity that results in earning miles will reset that expiration. These revised rules apply to miles accumulated both prior to and following that date, with accounts now updated to display the accurate expiration date.
For what it’s worth, this marks the first significant update to Flying Blue’s mileage expiration policy since 2017. Back then, the period of inactivity required before miles expired was extended from 20 months to 24 months.
## This is a reasonable policy shift from Flying Blue
I am quite pleased to see Flying Blue revise its policy, as it allows you to extend the expiration of your miles simply by transferring a small quantity of points from a transferable currency. This new policy is not only more generous, but also clearer, as the previous policy had caused confusion for many.
It’s refreshing to witness positive developments from a program without any hidden catches. Furthermore, I believe that a two-year mileage expiration policy is entirely justifiable. Personally, I’m not bothered if programs have miles that do not expire, as I would rather they allocate more resources to other areas for engaged members (considering that every benefit has its trade-offs and opportunity costs).
## In summary
The Air France-KLM Flying Blue program has enhanced its mileage expiration policy. Effective immediately (as of May 4, 2026), all Flying Blue miles will not expire as long as there is some earning activity conducted every 24 months.
Under the previous policy, only certain earning activities (including crediting flights and spending on a Flying Blue credit card) could prolong the expiration of miles, while miles accumulated through other avenues could not be utilized to extend the expiration.
