Thank you again for your help. Yes I reserved the seat although not the original date/time that I want. I am now shuffling my schedule :)
Also I tried the SBB apps and yes, it allow me to purchase the ticket upgrade for the route. I might do that when I arrive Switzerland and before I go for the Glacier Express.
Since the ticket is via the SBB app, so I am assuming it will come up on the app that I can show the conductor, not need to print, is my assumption correct ?
