Yes, Lufthansa Miles & More award miles generally expire after 36 months (three years) from the date they were earned. The expiration occurs at the end of the quarter in which the 36-month limit is reached. However, there are several ways to stop your points from expiring in 2026. First, if you hold Frequent Traveller, Senator, or HON Circle elite status, your miles do not expire as long as you maintain your status. Second, if you hold a Miles & More Credit Card (and meet specific criteria like making at least one purchase per month and having held the card for more than three months), your mileage expiration is paused. For everyone else, if you haven't used your miles within three years, they will be forfeited. You can track your "miles at risk of expiration" in your online account profile or through the Miles & More app. If you see miles about to expire, you can redeem them for "WorldShop" products, hotel stays, or flight awards to ensure you don't lose the value you have accumulated.
