In your carry on bag you should have;
Extra socks, extra underwear, all of your meds, sun screen, chap lip treatment, toilitries, your passport, your tip money, tickets, a gortex jacket, gortex pants, floppy hat, gloves and face net (sunburn). Wear your hunting boots on the plane. I bought a pair of Chipawa ankle height walking boots with a smooth sole. Also, depending on age, go get a pair of reinforced high stockings for your feet and legs, to prevent leg blood clots from sitting so long. You should have a complete outfit to wear on the first day, should your baggage get lost. We arrived on Sunday and did not see our luggage until Thursday night.
I hunt South America every year and have been to Africa. I have seen lost luggage and lost guns. Guns you can rent but hunting clothes can be a problem, especially good boots. Now I have a full set for one day with me.
I wear camo clothes everywhere I hunt. I am a bird hunter and like the shadow grass pattern by Mossy Oak. Ah, yes, no semi-auto shotguns in the RSA.
Next time I go to Africa I will stay 1 day in the hotel at the refueling stop, both ways. 16-18 hours is just too much for my back after my surgery. Going is pretty smooth, but the return ride is bumpy due to air currents.
If going into JoBerg, have a $20 in your pocket for the drink box. Pay the $ and shut up, unless you need a new address, the airport customs waiting room.
