BEFORE YOU GET IN TOUCH

Start with the ticket issuer

KLM’s refund guidance uses the ticket type, cabin and route to determine the applicable process. A refund flow can also cancel an eligible booking; read the proposed action before submitting it.

Identify who received payment for the ticket.
Use the official application or follow-up route appropriate to the stage of the request.
Keep the case reference and distinguish travel credit from a return to the original payment method.

Open refund information (opens in a new tab)

The number keeps its source’s department label. A general reservations line is not described as a dedicated refund hotline, and no refund result is promised.
