Hi,
I wish to make a reservation for the train Wien (24/06/23, 7.42pm) ➩ Bucarest (25/06/23, 3.05pm). I have a 2nd class pass. I wish to make a reservation for a single bed (I saw on the website of the train company that it was possible). Yet this option does not appear. Is it because it is an option not available for eurail ? Is it because it is available for 1st class pass ? If so, how can I change my pass from 2nd class to 1st class ? I did not made any reservation yet so I guess it could be possible ?
Thank you very much,
Amélie
