This issue of cabin luggage IS all of the airlines problem and is all their own doing - They now reap what they sewed by allowing in the first place 10-15 or so years ago the concept of cabin baggage only - take what you like and you don't have to pay blah blah blah for hold luggage
Joe P is not too blame here --- only the greed of the airlines trying to make a fast buck on charges and saving on ground handling - That greed now causes delays (shot themselves in the foot there lol) stress and problems to both the pax ground staff and crews onboard playing pass the bloody parcel of bags around the cabin and back into the hold etc
NOT IN MY DAY!
sorry no sympathies - The airlines created the monster
