Changing a seat reservation for Bernina Express

I booked 2 tickets for the Bernina Express through bahn.com they automatically assigned me a seat reservation. Is it possible to change my seat reservation? If not could I purchase another one? They gave us both inside aisle seats at least one of us would like the window.

Hi jkerro213, thanks for your first post here!

Whether you can change it depends on the conditions of Bahn.com. You can best contact them and ask about the options. Buying a new reservation is certainly possible, however if your travel date is close the window seats might be booked out.
