Hi, in line with HK's current transit requirements I would need some assistance with the following hypothetical scenario: 1. CX SYD-HKG (CX stock / cash booking); 2. AY HKG-HEL (Alaska stock / award booking).

I know these are 2 separate tickets, but if Alaska or Cathay agreed to put the entire itinerary under one booking (PNR) would travel and transit through HK be allowed? Trying to figure out what "Itinerary is contained in a single booking" exactly means. Thanks
