I know I might well be ridiculed and laughed at but I will take the risk.
Already done behind your back.
It is not a safety issue or a ticketing issue but an INSURANCE
and LIABILITY issue. Horse and gorilla attendants are covered
in the premium but any general publicants are not. Hence if a
freight mob accepted a bloke off the street for carriage he will
have to sign an Indemnity form before flight, which will free a
Company and its Insurer of any rights to claims by said bloke
for any injury and death. Much safer to fly pax aircraft and be
done with it esp if you have dependents.
Then again if your girlfriend resembles a gorilla and you bring
her along you're likely to be automatically covered!
