DO NOT BOOK THE EUROSTAR THROUGH TRAINLINE!! My parents booked 4 family members to travel between London and Paris. One of names given was a maiden name, not the married name which needed to be changed. After phoning and emailing backwards and forwards between Trainline and Eurostar on 3 separate occasions we were told categorically by Eurostar that only Trainline could change the name as they were the 3rd party booking company and they only had access to the tickets. So we called Trainline AGAIN and they said, 1) they did not have someone who could deal with Eurostar bookings........what? This was a blatant lie as I had spoken to someone 10 minutes before and 2) that there was NOBODY at Trainline who could change the name, not even when we asked for a Manager. After wasting lots of our precious time, it seems we CANNOT change a name on a EUROSTAR ticket when it is booked through Trainline. So don't book through Trainline - their process and service is shocking.
