We would like to travel from Zurich HB to Zurich Aiport on 17 Nov 2018 and want to buy the ticket online in advance.
We notice the ticket states:
Valid: Sun, 18.11.2018 dep 08:01
1 hour
does this mean we must take the train depart at 8:01 am or we can take any train from Zurich HB to the airport on 17 Nov 2018? the valid of 1 hours means valide from 08:01am to 09:01?
Thanks.
