Thank you for your earlier response with a link to the seating plans, but when I clicked on the recommended link and looked at trains originating in Switzerland going to Italy it said there are no seating plans available.
My booking number is RR4VHN for 2 people travelling from Zurich to Milan on train EuroCity 17 departing at 11:32 on 19 September. I received confirmation of my booking that we will be seating in carriage 2, seats 101 & 102. A seat plan of the carriage was attached, but there is no seat 101 in this carriage. So I presume there has been an error. Can you please confirm that we have 2 1st class seats reserved sitting together.
