Hello Fellow Travelers,
Quick question about seat upgrades on the Golden Pass Line. I reserved second class seats from Interlaken Ost to Zweisimmen, and first-class seats from Zweisimmen to Montreux. Then today I bought tickets online for the whole journey. But I did not see a way to upgrade to first class for the Zweisimmen to Montreux leg. I’m pretty sure I can do that once in Switzerland, right? But I’d really prefer to take care of it ahead of time. Is there a way to do this online?
Thank you.
