Not familar with AMS or NCL or KLM either. But looks like a wild rush to beat some night curfew (if AMS has one that is ) or the crws FDTL or something similar? "Let the pax go home atleast. luggage can wait!".
Wonderful thing - the possibilites you can dream up when you are nowhere near the picture.
(No I am not a tabloid journalist nor training to be one!)
