AN EXISTING TICKET
KLM’s manage-booking guidance and cash-refund page address different tasks. Check the ticket and original seller, then follow the route that corresponds to a change, cancellation or refund request.
Start with KLM Royal Dutch Airlines’s official booking or help resource below to find the route for your ticket. Look at the replacement flight and any fare difference before accepting a change.
A cancellation may lead to a credit, a refund or no remaining value, depending on the ticket and circumstances. Read the options shown by the airline or ticket seller before confirming.
Keep the cancellation confirmation. A refund request may be a separate step, and this directory cannot approve or process it.
