The injuries don't surprise me one jot. Just how long is the madness of 'persuading' passenger not to use the hold going to go on. I have a member of extended family who last year went from LAX to China for a tour with only hand baggage. This year it was India. Saves so much time.
Just how strong are the overhead bins supposed to be? I've seen several break just lately.
Money could be made in providing a service that people would not mind paying for. I'd gladly kiss my bags goodbye a day before I travel, seeing them go to a local collection agency, and onto whatever airport's security. That way, being gouged for money wouldn't be so painful.
There has to be a standard overhead case. Made for it and sold worldwide for the job. Laptop and camera okay, but NOTHING ELSE - and none of these daft clothes specially made to take a month's worth of small items in hidden pockets.
