How to get from Zurich Airport to Vorarlberg?

[julia98]

I finally managed to get a flight from the US back home. I will land in Zurich, but will need to get to Vorarlberg. I know that no public transportation is crossing the border these days. Can anyone tell me what public transportation to take, and how to get to the boarder? Should I buy my ticket online, or when I get to the airport in Zurich?
I can walk across the boarder, and my dad will pick me up wherever i will cross. Thanks for your help. Appreciate it.

Hi @julia98 

Please contact first the relevant embassy to see information on entry and travel restrictions.

Some trains are running. You may plan your trip on www.sbb.ch/en/ and purchase the ticket at the railway ticket counter.

We recommend that you check out the current traffic situation shortly before embarking on your journey

Kind regards
