Hi All, I need to get from JNB to Windhoek. I will be flying into JNB on BA getting in at 9:05am. There is an SAA flight at 1:20pm to Windhoek, Namibia.

Unfortunately, I will need to check a bag, as it is a long trip. If I reclaim my bag at the baggage claim, do I then need to go through customs, and go back through security, or can I "transit" through to the Windhoek departure gate after reclaiming my bag?
