Dear SBB Customer Service,

I hope you are doing well.

I am planning a trip to Switzerland in March 2027 and I would like to clarify whether the Saver Day Pass would cover my planned itinerary before purchasing it.

My itinerary in Switzerland will be:

Zurich → Interlaken
Interlaken → Lauterbrunnen and Grindelwald (round trips during my stay, returning to Interlaken/Zurich)
Zurich → Chur
Chur → St. Moritz
St. Moritz → Tirano via the Bernina railway line

I understand that the Saver Day Pass is valid on many routes within the Swiss public transportation network, but I would like to confirm the following points:

Is the Saver Day Pass valid for the entire route from Zurich to Interlaken?
Are the trains between Interlaken, Lauterbrunnen and Grindelwald included in the Saver Day Pass, including return journeys?
Is the route Zurich → Chur covered by the Saver Day Pass?
Is the route Chur → St. Moritz → Tirano (Bernina railway line) covered by the Saver Day Pass when traveling on regular regional trains?
If I choose the panoramic Bernina Express instead of regional trains, does the Saver Day Pass cover the train ticket and require only the mandatory seat reservation?
Is the Saver Day Pass valid until Tirano, Italy, or does the validity end at the Swiss border?
Are there any additional supplements, restrictions, or extra fees required for any of these routes when using the Saver Day Pass?

My goal is to use the Saver Day Pass for my main train journeys in Switzerland, including the Bernina route, and I would like to make sure that this is the most suitable ticket option for my itinerary.

Thank you very much for your assistance.

Kind regards,
Rafaella
