I would be very grateful for your advice. We are in Zurich for the day next Thursday, landing at 9.30 and leaving at 5. Can you please let me know if buying the 9 o'clock day pass for zones 110 & 121 is the most cost efficient manner to do the following:
1. Airport to HB at 10
2. HB to Loorenstrasse (zone 121) and back
3. HB To Albistrasse
4. Back to HB
Many thanks for your help!
