Mixed tickets

Seawhaphoa53

I have bought 2 tickets in second class between Luzern and Montreux via Interlaken Ost for 25th July 2025. But then I booked seat reservations in different classes; 2nd for Luzern-Interlaken and 1st for interlaken-Montreux. Could I changed sets reservations?
Thank you

Hello Seawhaphoa53

Seat reservations are usually not exchangeable and not refundable, but you could buy an upgrade from 2nd to 1st class between Interlaken and Montreux.

Otherwise you have to buy new reservations in 2nd class.
