I recently lost a bag between Chicago and New York.
I assume that anything I check may be lost. If you put any camera
equipment in a checked bag, make certain that you have insurance coverage.
The Airlines seem to have a much larger problem than is being disclosed,
or tracked. They are refusing to get the equipment that would monitor
the bags with electronic chips, that retailers are now using.
