Well lounge access will be great... I like the RDM's I have been lucky with redemptions.. Recently did DXB-LHR-SFO-LHR on Low J with VS.. I'm looking forward to one way redemptions.. So the miles are good.. I like Saudi.. Only flown J, but they are a decent airline (although no booze is rough) JED lounge can be bought into for a small bribe if need be.. As for JNB.. Love SA.. Might use some Avios for a side trip

All great.. I just realized 50% MQM on cheapo SV tickets.. So back to the drawing board
