Hi,
I was coming back from a long trip on June 15th (last Friday) and waited for the S8 in the Airport for about an hour (from around 20:15 till around 21:15). They were cancelling the trips, both of S1 and S8, one by one. I got fed up and took a taxi home.
The MVV office in Airport did refund me the ticket cost :-)
Any idea what had happened and how long this disruption was?
