Thank you very much for contacting us. You can take any of the trains that go from the Zurich HB to the Airport. They run 6-8 times per hour (Cost of CHF 6.80 one way). Depends on the time you are leaving. A Taxi ride would cost you CHF 50,- to 60,-
Sounds good how far is the train station?
Walk to the HB and take the next train to the airport.
The train station is 2 mins walking distance from the hotel.
I preferred to take the taxi since I had lot of luggage and carrying that in train seemed a bit more cumbersome to me.
The Taxi ride cost me around 35CHF. We were three people and we had 5 bags in total. This was in the month of October 2016.
