What does this mean for you?

  • You can book your trip to or from London as usual. Once you have made the booking, you will see the text: 'Complete your passenger details'. There is a link to Eurostar's site where you can fill in the additional passenger details.
  • Once you have entered your details on, you can download your ticket immediately. You must do this before checking in at the station.
  • After you have booked a ticket from or to London, you will receive an email from us confirming your booking. The email will contain a link that will allow you to download tickets. These are then tickets from your journey to the boarding station of your international train. For example, if you have booked a ticket Alkmaar to London.
  • If you have not filled in your details completely, you will not be able to check in!
