Does anyone know what baggage allowance applies when ticketed for BA CPT-JNB (business) connecting to the QF flight JNB-SYD (first)?. In MMB it says 3 bags at 23kg each for both flights, but does say the allowance only applies to BA flights. I did see a notice on BA.com that says BA will apply the most generous allowance for the booking - so if BA in SA allows three bags then I could check the same through to SYD? There is no mention of a specific allowance for internal SA flights on BA.com.

Thanks in advance.
