I don't know about BA/SAA but the other day it was cheaper to route JNB/AMS/SYD on KLM than it was to go direct JNB/SYD on SAA.
In November it is very considerably cheaper to route SYD/SIN/JNB on Singapore than direct on SAA.
In those cases of course the flights are longer. But there is an upside to not flying SAA especially when you consider that you might end up on a Qantas flight, two of the world's truly appalling customer service airlines.
