Why on Earth was that nasty, unpleasant little kid allowed to fly? Flying is not a right and it is unfair, unjust and selfish in the extreme to allow that kid to inflict misery on those who have the misfortune to share a (long haul) flight with it. I would have offloaded “Little Precious” and mother without any problem whatsoever. If they want to travel, they sedate the kid or make alternative travel arrangements.
