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
A little context helps.
Find the published KLM Royal Dutch Airlines contact and choose a telephone or online option by its stated purpose. A booking reference identifies your reservation; it is not a customer-service telephone number.
- Read the calling region and department beside the number.
- Use the airline’s own destination to share a booking reference or passenger details.
