I have been through Johannesburg 5 times with firearms when hunting in SA, if you do all the paperwork in advance and have colour printed copies of all the additional paperwork they require, FAC ticket, passport, letter of invitation, flight details I found it relatively straight forward. The main entry desk where you are reunited with your firearms no angling for cash on the last 3 trips however if you are doing an internal flight the guys in the station desk a couple of floors up always “ask” for some reward. Great thing with hunting in Namibia is you do still go through Johannesburg but your rifle is checked straight through so you never see it till you get to Windhoek where there is a very simple firearms procedureI have to say that my trophies have taken from as little as 6 months up to a year, but the quality of them has been excellent. Although SAA are ok now, the biggest issue was that they have dumped their own internal services. This means changing operator's at either Capetown or Jo'Burg. This limits the carriers of firearms and the airports you can get to. Collecting and rebooking in firearms adds more time and fees as well. If you can, go vi Capetown rather than Joburg though. Much better set up there.
