Choose the right KLM Royal Dutch Airlines contact

KLM's US customer commitment lists a toll-free flight-information contact and directs travellers to its own help channels.

Before calling

  • Match the contact to your question before calling.
  • Keep booking or case references ready; enter sensitive information only on the airline's own services.

Check the country and department next to a number. A reservations line may not handle baggage claims, bank cards or a travel agency’s ticket.

Prefer an online route?

Open the airline’s own contact page to see its current chat, forms and country-specific options. An email form or social profile is not necessarily monitored for urgent travel.
