Can I buy a half fare card at the Zurich airport on arrival to Switzerland? The current SBB website is not showing where I can buy a one month half fare card, it only shows the pricing for one year.
There are 6 of us traveling for 6 days from Zurich to Lausaane to Interlaken and return. Travelers are 55, 56, 78, 81, 16, 21. I am considering buying the half fare card with the Bernese Oberland pass. Is this a good idea considering I have two youths with us
