I'm travelling from KUL-YYZ soon with my wife and 1 yr old daughter on the same PNR, myself a silver and my wife's a green. In my previous flight when travelling by myself to LHR, I have been op-upped on both the KUL-HKG and HKG-KUL legs without any attempts to get bn1 - both legs were late check-ins.

For this trip, I've gotten the bn1 for both KUL-HKG and HKG-YYZ, so we'll see what happens next.
