Obviously nothing is impossible, but I don't think KA will need to look outside HKG for cadet pilots. The company currently don't need as many pilots as Cathay, nor do they have as many incoming aircraft or route expansions either. I also don't think the company itself has the resources to conduct interviews for expatriate applicants. Unless there is a major exodus of pilots from Dragonair, it is hard to see them resorting to recruiting expatriates for their CPP.
That being said though, a turn in the rumour mill is indicating cadet pilot intake will increase next year.
