Perhaps children shouldn't be seated under overhead bins?
In 2010 they had a 10kg limit now everyone wants a higher carry on limit. Seems to me you can't win.
Its a difficult one but was once absued when travelling on a US flight becasue I wouldn't help a lady who dragged her bags on to put it in o/head...............they looked heavy. Asked if she would cover my hospital bills if hurt my back.
2 other passengers lifted it but really was ott and F/A said too heavy has to go below to outrage.
Captain got involved as heard the lady swearing and suggested she take another flight. Hate to think what would have happened if it had come down.
Maybe time for electronic locks that only open after landing when plane has shut down.
