We will be trying TGV for the first time in May. I went online and bought our TGV tickets and last week I got this email and I wondered how worried I should be that this will be difficult to clear up at the station???
This is regarding your travel booking with SNCF on 17/05/2018 on train
9812 from AEROPORT CDG2 TGV to LYON PART DIEU.We'd like to inform you that there could be a change in your coach or
seat number due to technical problems. To assist you, our station
staff will be available on the platform.
Thanks Donna
