The FA deserves no sympathy whatsoever. As witnesses have stated, she was told that the carrier held the dog, but insisted that the carrier went into the overhead locker. Quite how anyone can be so dim-witted is beyond me.
Nevertheless, United have admitted that they were wrong, so it will now be a matter for the lawyers to secure the best possible compensation for the grieving family. I hope that they will soon have another French Bulldog to cherish, but it will be a long time before they will be able to overcome their grief over this shocking event.
