Loads on the HKGSYD sector are picking up - all 3 cabins too (Upper, Premium and Economy) - and the route is turning a profit. I have just come back from a HKG-SYD trip and the LHR-HKG sectors were both chockers, the HKG-SYD sectors too were quite busy, although all staff did get on - there is a lot of pax originating in either SYD or HKG and just going to the opposing destination.
Once VS starts the second daily LHR-HKG (slated apparently for August or so) the HKG-SYD flights will fill up even more...
