How far advance can seat reservation can be made for SNCF/TGV train from Switzerland (Basel or Zurich) or Strasbourg to Paris?? We are planning to travel at the end of May.
Currently not too many options showing on SNCF website, and on Eurail website, all show Pass not Valid, I understand it is too soon to make a seat reservation, but can anyone help me with the timeline please ??
Thanks so much
