I’ve watched flight attendants move customers’ belongings in the overhead. If a passenger speaks up, afraid their computer for instance might disappear to camera equipment could get damaged, the passenger is immediately put on notice: are we going to have a problem? In other words sit down, shut up, or you’re off the flight.
Since the David Dao dragging incident on United last April there’s been more attention paid to the problem of airlines turning customer service problems over to law enforcement.
