Don't want to miss Bernina Express & Centovalli

I will be in Switzerland May 2016. I understand I can buy the half fare card now, however, I dont know how can I buy the Bernina Express ticket using the half fare card. I can't wait until i get there to buy the BEX ticket because I'm affraid it will be sold out. I only have one day available for this and is a saturday.

Same goes for the centovalli Railway.

Thank you

No worries katyka9. Here's how it works:

• You can indeed purchase the Swiss Half Fare Card at any time from the retailers listed here. It makes sense to do so before Christmas as I expect prices in other currencies than CHF to rise next year. But, no guarantees!
• You can buy your discounted ticket whenever you want. You don't need the Swiss Half Fare Card to do so. They don't sell out.
• The only thing you do need to buy in advance is a seat reservation. They do sell out.

Thank you Arno, So to make sure that I understand. I can buy the BEX ticket once I'm in Switzerland, and I can buy it with the half fare card. However, I do need to buy in advanced the seat reservation for the BEX (which it does not have a discount).

My question: So by having a seat reservation, it guaranties me that I will get on the BEX?

is the same deal for the Centoville Railway?

Thank you!

Yes, exactly! Centovalli works like that too, although I am not sure if you actually need a reservation and/or surcharge for all trains on that line. You can check that in the timetable.
