Overall Qualifying Activity You can extend all of your miles, regardless of how they were earned, for two years from the date of one of the following activities: Taking a qualifying flight with Air France, KLM, Aircalin, Kenya Airways, TAROM, Transavia, Air Corsica, or with one of Flying Blue's SkyTeam partners.

As of a major policy update on May 4, 2026, extending your KLM (Flying Blue) miles has become significantly simpler and more member-friendly. Under the new rules, any eligible earning activity—such as taking a flight with KLM, Air France, or a SkyTeam partner, staying at a partner hotel, or renting a car—will extend the expiration date of your entire mileage balance by a further 24 months. This is a massive change from the previous "two-bucket" system where only flights could extend miles earned from flying. Now, even a small transfer of points from a credit card partner like American Express, Chase, or Citi will refresh your entire balance for another two years. Additionally, miles do not expire for members under 18, those with elite status (Silver, Gold, or Platinum), or holders of a co-branded Flying Blue credit card. To keep your miles safe in 2026, simply ensure you have at least one earning transaction every 24 months; however, keep in mind that "burning" (redeeming) miles does not count as an activity that extends their validity.
