The fastest I get to my destination with the fewest layovers is what I want. I think that reduces the chance that rifle and gear don't make it to the destination with me.
I fail to see how flying from Texas to Dubai to get to Africa is faster or with fewer layovers than using SAA or Delta from the east coast of the USA. I hope you are saving many hundreds or thousands and are bumped to first class.
That's one way to look at it, I don't see it that way.
I'd pay an extra $5000 to fly through Dubai for many reasons.
1. They don't screw around. If you have your permits they don't want your guns. When you leave, they are eager to see your guns leave too.
2. You avoid check through issues in Jo'burg which can go poorly. I lost two days due to Jo'burg gun mishandling at a blended daily cost of $2700....it cost me two days and over $5400 in lost hunting time to connect in Jo'burg and let them touch/lose my guns. Emirates direct to destination avoids that issue.
3. No overnight at Afton house with Dubai usually
4. Less US transfers. Odds are higher an American worker will intentionally lose your guns to make a political statement. I'll put my faith in Emirates instead.
5. Best airline in the world. Why fly second best for more?
6. Total transit time is the same
7. Layovers in Dubai are holidays in their own right, even if for a few hours
8. Guns usually checked through end to end
