I fly for an airline in China. One of our flights had one passenger missing at the headcount. Several attempts were made to rectify the discrepancy but the number of boarding cards matched the manifest, but there was still one passenger less on the aircraft. Then one of the cabin crew noticed a little old Chinese lady holding an urn to her chest. Yep, she was returing her deceased husband to the ancestral home for burial (v.impotant to Chinese) and she had bought him a ticket! Not only that, but the check in staff had checked him in.
We now have a stated policy that souls of the decased fly for free!
