Dang, I would be livid. I have owned several guitars worth well over $2k each, some over $5k or more now a days. They were all vintage Gibson / Fender oldies and a Rickenbacker Checkerboard Bass. When I was a Rock n Roller, I always demanded my axes ride with me. If the airline wouldn't agree, I didn't fly and this is why! I can't quite fault DAL in this as it may have been a bag belt issue at the airport but someone SHOULD have minding the store. Still a shame this man lost a valuable instrument that he makes his living with. That instument will never play the same again!
