I am looking to buy a Swiss Travel Pass for 6 days (flex). I understand that the Swiss Travel Pass does not cover the ticket (Top of Europe) from Grinderwald to Jungfraujoch -and that separate ticket is needed. The fact I have a Swiss Travel Pass would entitle me to a discount on the separate ticket. The question I have is if I am to use the Swiss Travel Pass (solely for the purpose of buying the separate ticket) and not for intercity travelling, would that count as using 1-day of Swiss Travel Pass?
So for example, from Day 1 I would use Swiss Travel Pass to go from Interlaken to Grinderwald, for Day 2 I would begin my journey from Grinderwald to Top of Europe (without taking any SBB train), but I would need to use my Swiss Travel Pass to buy the separate discount ticket. Would Day 2 constitute 1-day of use out of my 6-day Swiss Travel Pass? I think the answer is no, but I would be grateful if someone can confirm. I have tried to ascertain the position from live agent but no answer was given
