I wonder if these airlines have any idea how truly disruptive mishandled bag situations are; aside from the inconvenience of being separated from one's necessities, the nuisance of relying on delivery services (and their dubious accuracy), byzantine communication processes/collective outsourcing, and "angst" makes for a very difficult and stressful experience for the owner of the misplaced bag. Then there's always the "fear" that the bag will never be recovered, etc.... By the way, my bag was scheduled for delivery at 730am. I got a text indicating it had been delivered (but it hadn't) - and the online map showed the hotel next door (the Fairmont) instead of where I am - that led to a frantic run over there, etc. Just crazy.
By the time I got back to my own hotel, (the bag hadn't been delivered even then), I started a panicky call to UAL, and only then, did the driver show up, almost 3 hours later than committed, and 15 mins after the app said it was delivered.
