Accountability sinks

I remember experiencing this in one of the German airports/airlines and having that exact thought.

It was this fully automated airport, where the checkin is self serviced and you only interact with computers.

Eventually, when I inserted my boarding pass I had a printed piece of paper back that said that they had to change my seat from aisle to midseat

I then tried to find someone to talk to the entire way, but computers can only interact in the way the UI was designed, and no programmer accounted or cared for my scenario

The ground attendant couldn't have done anything of course because it wasn't part of the scope of her job, and this was the part of germany where nice was not one of their stereotypes.

Eventually I got a survey a week later about a different leg of the flight, so could I really complain there? that one was fine? I had a paranoid wonder if that was intentional

I can provide another POV to that story. We checked in as a family of four, and we're assigned seats in four different rows, with a two and a four year old. Only when entering the plane we had the possibility address this to a human and we were assigned new seats.

So this might be the reason you had to change seats.
