they do things like walking on a wire and the HK limitation is very hard to bust. what they did to deal with the crew shortage was doing o/n SVO in the past 2 months and continue to offer short term contract for pilots from Airbus. this may also is the reason for so many cancelation of their early morning BJS service. they were busted once by the HKCAD of allowing all airbus crew to operate the flight on their behalf, in short, no HKA a330 pilots onboard.
