So I'm trying to price out ticket prices and figure out what passes might be economical but I'm confused about getting accurate pricing. For example, let's say I want to go from Lauterbrunnen to Schynigge Platte via Wilderswil. According to the Jungfrau pricelist found here (https://cdn.jungfrau.ch/Prospekte_und_Broschueren/Jungfraubahnen_Fahrpreise_Preisliste.pdf), it's 38 CHF one-way.
But according to sbb.ch/en, it's showing as 19 CHF. Can someone help me with this?
