New journeys
Reservations & booking
For a new KLM Royal Dutch Airlines itinerary, prepare the dates, airports and travellers before opening the airline’s booking tools or contacting reservations.
- Compare the fare rules and the full price, including any channel or agency charge.
- Keep the confirmation from the seller that accepts the booking.
Existing tickets
Changes, cancellation & refunds
An amendment to a KLM Royal Dutch Airlines journey begins with the existing ticket and its issuer. Changing travel, cancelling travel and asking for money back are separate requests.
A useful first step
Before you contact
KLM Royal Dutch Airlines
Use the KLM Royal Dutch Airlines contact record to choose a channel before sharing case details. Keep baggage documents separate from receipts for the flight itself. Read the company’s latest instructions if your situation depends on a deadline.
- 01
Name the operating airline as well as the business that issued your ticket.
- 02
If you have already opened a case, continue with that reference rather than starting several requests.
- 03
Keep baggage documents separate from receipts for the flight itself.
