I dunno. Maybe 10,000 Dollar guitars shouldn't be lugged around on flights. There is a reason why even people who can absolutely afford it leave their priced possessions at home and tour with something replaceable. How often have I read "but she's not touring anymore, she stays at home now". And if you insist on taking it with, buy a real flight case that won't allow you to take it on board ever, but will protect it while it is processed. I probably only have one 10,000 Dollar bass - my 1963 (or is it 61?) EB-6 - and I wouldn't travel that on a plane without the sturdiest Panzer flightcase avaiable if at all.
I don't think Delta acted/bungled/mangled like United did with throwing the Taylor about. Tough luck and inadequate protection for conveyor belt processing. Plus a haphazard approach for a working musician, he obviously relied on talking people into being allowed to take it on board. That works nine times out of ten only ...
Now stone me.
