Right, Captain Ban was the alternate Captain, my mistake. I believe Claus Andreson was the captain and he moved on to other ships after the incident.
One of several threads from the time:
Captain Ban is still at the helm of Q class ships and no, sales didn't go down on Athem or other ships after that incident (106.4% occupancy in 2016, the year of the incident and 108.4% in 2017). Folks have short memories, despite the media hype.
No, call C&A directly and tell them you sailed on a solo booking -they may tell you their system says otherwise at which point you'll have to take up the issue with your TA.
