I don't know what the "rifle permit" requirement/documentation is for Zim, but when flying from DIA to DFW on AA this past June enroute for a RSA hunt, it became a real hassle with the ticket agent and her supervisor (both clueless). They wanted to see the permit from SAPS. I showed them a completed copy of the SAPS application and the email from Rifle Permits stating the actual SAPS permit was pre approved and waiting for me upon my arrival in JNB. They also wanted paperwork from Qatar showing the transfer of the firearms to them. I only had Qatar's "Surrender of Firearms" completed document. After about 45 minutes on the Qatar "help" line, the ticket agent weighed and tagged my gun case, yelled for a Customs agent and walked away from the counter. I looked around and saw no customs agent, so I found an employee with a cart who took me to the customs office for an xray (no physical inspection) of my gun case. The employee then took my case and stated he would make sure it got on the flight. Gotta love it! LOL
Anyway, to all of the members going on your fantastic hunting adventure, have a great time, shoot straight and don't take any wooden Zim coinage!
