SBB Pricing
Hello everyone!
Just wondering how SBB pricing works. For context I have GA. I’m planning to buy a ticket from Biel/Bienne to Munich. Since the route passes through Zurich, I checked the price from Biel to Munich and then compared it with the price from Zürich Hauptbahnhof to Munich.
My understanding was that there should be no price difference, because my GA already covers the Swiss part of the journey, including Biel to Zurich.
However, when I compare the prices in the SBB app, there is still a price difference between the two options (see attached photos). I’m confused about why there is a gap.
Can anyone explain how this works? Does the GA not fully deduct the Swiss portion when booking international tickets, or is there another reason for the price difference?
Thanks in advance!
