On BernerOberland pass website, there was this FAQ ...
It asked.. "Do I also pay CHF 99 - for a trip to the Jungfraujoch with a Half-Fare Card and a B-O pass??
It answered.."From the Eigergletscher station you pay CHF 75 return. You can buy the ticket online or directly on site."
The B-O pass brochure states it is CHF99 to Jungfraujoch, but on the website it says 75CHF.. what am I missing??
