Are you planning on purchasing a ticket or using miles?
If you are buying a ticket you can use an AA SWU on the AA flight, if you are using miles you cannot. If you want to use AA miles you can fly AA to MAD and then fly IB MAD-JNB. If you are purchasing a ticket fly AA to MAD (use your VIP/SWU) and then use AA miles on IB MAD-JNB.
Similarly you could buy a ticket on AA to PVG (use your VIP/SWU) and use miles on CX to JNB.
