Hi
I've been looking details every where on when We must use travel day or not to get travel discount in interlaken - first - jungfraujoch. Seems like the infos are confusing.

One site tells that we need travel day to get discount.
While on the thread of this community said that travel day are no need.
Which info is the correct one?
Or can it be verified on the interlaken ost Station?
Thank you in advance
