This past August I went:
Houston - Dulles - Jburg - Windhoek. Returned: Windhoek - Jburg - JFK......
The reason was to check bags to final destination Windhoek & not overnight in Jburg (or anywhere) to avoid claiming firearms in both ways (esp. SA). Didn't mind the extra legs at all. Flew SAA- very happy. (Was on the local to Jburg with the one non disembark stop in Accra. Return was the express to JFK.)
Good luck.
