Why not hire a driver from Lusaka to Kariba (3 hrs+) on an already 1/3 too long series of flights to get to Zim?? The Qatar flight setup looks very nice, but that will come to a successful conclusion after that! You'd see things never imagined from the air! A $20 spot at the border crossing will get you going in minutes (as opposed to hrs!)
I just have issues with flying beyond Africa and then back. SMH. Limit the risk. Buffalo? Elephant? Guessing the former with time for the bolt and the double. 30 hrs 1-way?? It's taken only 20 ish hrs for that in the past...Including a flight to SA, Windhoek and then the Caprivi or SA to Harare (same general mileage to destinations.) 20 more hrs (a day!) in flight time, no matter how comfy, just seems a waste. That's 2 days hunting or 2 days sooner to return home! Was a travel agency involved? All that said, enjoy whatev it is you're hunting! Show us a map of the flight plan...
