Hi,
I am looking to do a night train from Zurich to Ljubijana on May 23rd for the 20:40. I am very confused on the person. It says I need to buy a seat reservation of USD $18.53. Okay makes sense there. However when I go to OEBB website and click Seat Reservation only it says no tickets available. When I unclick that box, it shows me the cost of OEBB ticket starting at 55 euros and then whatever seat I want.
I guess my question is, when I pay on Eurail for the seat reservation of $18.53, am I getting some sort of seat on OEBB or do I have to do something else on OEBB website?
