We plan on taking the direct train from Zurich Airport to Interlaken via Bern. We plan on buying the Swiss Half Fare Card and BO pass. We will be spending all of our time in the BO region (except for the to/from Zurich).
My question is since the BO Pass covers the train from Bern to Interlaken, do I just pay for the fare/ticket from Zurich Airport to Bern before getting on the train?
