Brunos As I recall my post mentioned that CX is a British own and operated airline -which it is
The word controlled = to control
While I don't for one moment wholly discount that which you mention above the indisputable fact is that the airline while a publicly listed HK company its controlling and major shareholder is British as of course it has been for decades.
To proclaim otherwise is just incorrect and however loud you shout CX is since 1948 a British owned airline operated as a subsidiary of British owned Swire group who control the airline and directly own 42% of the shares and indirectly a further about 6%.
