Eight violins ‘lost’ on US Airways

This just in from Ken Kulosa, teacher of cello at Washington University, St Louis:

US Airways has lost my violins!

I am making an appeal for help from employees, managers, and/or executives from US Airways to help us get action in the process, which has been full of roadblocks, passing the buck, and “we can’t make the call”. It appears as though US Airways simply doesn’t care, or doesn’t want to try.
We last saw our 8-violin shipping trunk as we passed it off to oversize baggage in Barcelona on Wednesday the 19th. As far as the airline can tell us, no trace since, as it was never scanned into the system. After hundreds of calls: to the airline, as well as our own exhaustive investigations, we have gotten basically nowhere…..we very much fear theft, certainly at the very least, massive negligence.
All we ask for is a physical inspection of the facility, but they refuse to even make a call to Barcelona, just emails that go without a response.
Over the years, the one thing I’ve learned about airlines is when they say they can’t do something, it just means they don’t want to bother. This is devastating….please PM me if anyone can help, or can put me in touch someone that can, or simply more details.

My many thanks to all!
