Does SAA provide boarding passes if pax are connecting to another Star Alliance carrier? I am doing CPT-JNB-LUN-ADD (first two segments on SAA and third on Ethiopian, all same record).

Hope CPT agents are not as strict as JNB agents are with carry-on luggage at check-in. JNB even staffs airport contract workers at security checkpoints to weigh hand baggage before passing through to the airside area.
