Does the rule ‘only valid on specific journeys’ also apply on connections to/from SBB services? For example if I buy a SuSa ticket for Zürich Letzigrund via T2 & T3 to Zürich HB to Nyon and B810 to my village am I required to take the exact Trams and Buses indicated on the tickets? Or could I head to the city centre a couple of hours earlier and/or take a later bus from Nyon?
I don’t want to break the rules but the app won’t give me a SuSa for the actual journey I want, only the best connections to/from the train.
