Hi,
I am trying to book a ticket from Luzern to Interlaken on 14th May morning,

It says reservation is not required, so if I am not purchasing this seat reservation then,
- If seat reservations are unnecessary, can I just board a first-class compartment and choose any seat which is free(available)?
- If yes, how can I identify vacant seats as I travel from one point to another?
- If no, where can I find seating without having to stand for the duration of the journey, considering that I haven't purchased a seat reservation?
