Take a look at the deals section in Africa Hunting Forum. Probably the funnest way to do this is to post that you are looking for a hunt and watch the outfitters reply with offers. The rand to dollar exchange rate is good for us and really bad for them. They are fighting for business right now.
I am booking a hunt for May of 2017 and I am checking prices of flights weekly. I flew out of Sacramento on my first trip and Portland on the next. This up and coming trip will likely be out of San Francisco due to the favorable price of flights.
Last thing, most outfitters will be posting their specials in January or February, just in time for the hunting shows.
Africa is addicting. Dont plan on going once as you will undoubtedly want to go again and again. This will be my third trip. After that, I hope to go to Europe to kill roebuck and other species.
Good Luck and have fun.
