I bought two TGV tickets from Paris to Bruxelles (directly with Thalys.com) totaling 58 euros for a mid-May trip that I am cancelling. I just got an email from Thalys saying that I can change the reservation, but I would need to call in order to do so. I have no interest in doing that, and I won't be able to return within a year anyway, so if anyone is interested in the credit please DM me. I haven't waded through the fine print, so it's possible that transferring isn't allowed. The recipient doing that research would be part of the bargain.
