Hello, I bought a ticket from Wengen to Domodossola for my trip. However, I had change in plans which now, I will be coming from Interlaken OST to Domodossola. The ticket purchased is a supersaver ticket. The terms say, I can only ride the specific train, connection, and time, in the ticket. With that, may I know if I can skip the Wengen to Interlaken OST part of the supersaver ticket and board the Interlaken OST part of the ticket only? If I miss the first part of my ticket (no scanning), will it cancel the whole trip? Thank you in advance!
