In 2009 my wife and I were returning from Puerto Rico. A fellow passenger had bought a bottle of rum and had it carefully packaged - it was labelled « Fragile » and could not be brought as carry-on.
From my window seat I watched the loading crew as they stacked everyone’s checked luggage. The crew actually handled the fragile package of rum with great care. They set the package aside and the rum was the last item to be placed in the luggage compartment.
On arrival in Detroit, the luggage hatch was opened by the crew, the fragile rum package was picked up and tossed onto the luggage wagon, with all other suitcases and bags thrown over top.
The last item to come out on the luggage carousel was the leaky and severely dented « fragile » package.
This does not answer your question, but others have done so nicely anyway.
