Hi, I have trains booked between Paris-Brussels and Brussels-Amsterdam in Nov, for myself and a friend. Unfortunately, my friend can't come on this trip now, so I might bring another friend. the train tickets are booked as semi-flex, so they are 50% refundable, but able to be exchanged 1 time without any penalties. Has anyone been able to exchange Thalys tickets to another person, or are they specific to the name of the passenger (and does the passenger have to produce ID to be able to use them)? I do plan to call Thalys about this, but just wondering if anyone has come across this situation?
