I booked a journey for my family from Milan to Paris just before the closure of the Gotthard Tunnel. We had to buy seat reservations for Milan-Basel and for Strasbourg-Paris. I’m now concerned that we will be delayed on the way to Basel and won’t be able to make our SNCF train from Strasbourg-Paris.
I would like to change our Strasbourg-Paris train to a later one so that we don’t stress about making the connection or changing tickets on the day, but SNCF doesn’t seem to allow seat reservation changes. Does anyone know how we might be able to make a seat reservation change in advance of the journey? Thanks!
