Getting to Namibia
How would you go from Dallas/Fort Worth (DFW) to Windhoek Hosea Kutako International Airport (IATA: WDH, ICAO: FYWH)? Well, big warning first, none of the online travel site knows where WDH is, so you'll only see flights in $8,000 range! Call a local travel agency and the price should come down to the $1,000 - $1,500 range!
Best way (especially for those with hunting rifles) is to get to Frankfurt, Germany and then fly with
Namibia Airlines (oops no more) Eurowings Discover to Windhoek (Two flights daily in July 2022).
Since Lufthansa is not the most affordable, the next best is to go via Atlanta, JFK or Dulles (Washington D.C.) to Johannesburg (16 hours), and then on to Windhoek (multiple 1.5 hour flights in the day).
If you don't like 16 hour flights, then fly to Europe first and then to Johannesburg. Just be careful not to end up at Gatwick and need to fly out from Heathrow (which is going to cost you a British hunting rifle import license if you are going hunting)
There are also flights to Doha in Qatar with Qatar Airways (just 28.5 hours with a 4.5 hour layover)
