You can get a cash refund from KLM in 2026 if your flight was cancelled and you chose not to take an alternative flight, or if your flight was delayed by more than 3 hours (within Europe) or 5 hours (intercontinental). For voluntary cancellations, eligibility depends on your fare type: "Flex" tickets are generally refundable for a fee or free of charge, while "Light" and "Standard" tickets are typically non-refundable. However, you can always request a refund for unused airport taxes even on non-refundable tickets. Refund requests are processed via KLM's online system, usually taking two to four weeks. In 2026, it is a high-value peer tip to check if you qualify for an "exceptional refund" due to denied visas or the death of a close family member. If you booked through a travel agent, you must contact them first, as they hold the original payment authority and are responsible for initiating the return of your funds.
