Just looking at KL757 (AMS-PTY) on 12/12/2020 and I see that the seat map looks very strange. On J, 11 seats are blocked, and on Y, all but 4 seats are available. On ExpertFlyer I'm getting the following error:
There was an error message from the airline when trying to retrieve this seat map: PRS NOT ALLOWED THIS CLASS OR ZONE
Any knows what happened? Flight possibly going to get cancelled?
