Hence the 24 hour rule applies to CX connections in HKG -- very convenient. SIN can too, but NRT, LHR and LAX cannot, for example. I've chosen to route via HKG instead of NRT precisely because of this factor for some trips (even going to the extent of requiring people to fly NRT-HKG-NRT to meet with me as I did not go via NRT). So a strategy that pays off for HKG and CX in attracting more business by providing this service.
