Here's a troubleshoot guide to help you if you can't bring up the passenger's booking.
GDS reference error: We are experiencing an ongoing issue regarding some of the references being generated for Eurostar bookings within the GDS. To find out more click here.
Space in the surname: Our system does not recognise spaces, even if a space has been put in the surname when making the booking. Please enter the surname without any spaces.
Internet browser: Google Chrome is the best internet browser optimised to our website, sometimes using other browsers, such as Internet Explorer, can cause issues when trying to access your tickets.
Cookies: Deleting your cookies can sometimes help as they remember what has been entered previously on the web page. You can delete your cookies by following the guide here.
Open Jaws: We do not support open jaws. If an open jaw is booked Manage Your Booking will only show one leg of the journey and will likely show a long, unrealistic journey time.
Divided PNRs: Divided PNRs will not allow you into Manage Your Booking unless you have the native Eurostar reference which you will need to get from the GDS Helpdesk. Their contact details can be found here.
