KLM's flight cancellation policy provides passengers with options depending on the circumstances of the cancellation and the type of ticket purchased. If you need to cancel your flight, you must do so through KLM’s official website, customer service, or at the airport. The policy differs for refundable and non-refundable tickets.

For refundable tickets, you are generally entitled to a full refund if you cancel within a specified timeframe, usually within 24 hours of booking or if the flight is canceled by KLM. However, for cancellations after this window, you may receive a partial refund, depending on the fare rules of your ticket. Refunds are processed to the original form of payment and may take several weeks.

For non-refundable tickets, cancellations typically do not result in a refund. However, you may still be eligible to change your flight for a fee, depending on availability. If KLM cancels the flight, you are entitled to a refund, rebooking options, or an alternative route. In some cases, if you cancel for specific reasons, such as illness or other emergencies, KLM may offer flexibility or provide vouchers for future travel.

In cases of extraordinary circumstances (e.g., severe weather or strikes), KLM will assist affected passengers with rebooking or compensation. Always check the specific conditions of your ticket before proceeding with cancellation or changes, as policies can vary based on the type of fare and booking conditions.
