Seams the idiots are becoming more common. Just last summer I had the Ethiopian Airlines gun luggage rules printed and in hand. The SA booking agent at the desk handling check ins for Ethiopian in Joberg still charged me a $40 fee for firearms. After trying to explain for some time, she stated, you cannot board until you pay, with time getting short I just went and paid fee.
As for bolt rule above I have never encountered it. Last few safaris I travelled with bolt in gun, with trigger locks on and then locked in gun case. Never had any issues. As some state about extra scopes, being Canadian I am sure there are rules concerning such. I had to register my guns, ammo, scopes before leaving Canada and have a customs officer verify and sign document stating all I took out were returned to Canada, I then sent copy to Gov, all this for a SA hunt.
