General airline assistance. The airline or ticket seller determines whether a booking can be changed, cancelled or refunded; this is not a dedicated refund hotline.

Toll-free applies in the listed calling region. Mobile airtime or international charges may apply.

Independent contact reference. Hazel Milepost is not KLM Royal Dutch Airlines’s customer-service team. The number and external routes belong to the named provider. We do not answer, transfer or record calls.
BEFORE YOU GET IN TOUCH

Changing your plans

KLM distinguishes standard bookings, Flying Blue reward tickets and bookings made through an agency. Its cancellation guidance sends agency tickets to the agent and reward tickets to Flying Blue support.

  1. Use My Trip to identify the booking and affected passengers.
  2. For larger travelling parties, check whether assistance is required.
