I'm flying Niki from Zurich to Vienna, arriving at 10:15, and would like to catch an intercity bus from the airport to Budapest. I know VIE is a small airport and this Niki flight has a very good on-time record.

How long will it take me to make my way to the bus station? Will I be able to make the 11:15 bus? Or should I play it safe and book the 11:55?

Thanks.
