So this now likely becomes a political issue - which is unlikely to auger well.
If rights diverted to HX or "Greater Bay Airlines" (on basis that Shenzhen is no longer deemed "foreign" by the ATLA - witness HX ownership also) then CX likely to face much stiffer competition overall when flights resume in earnest.
It is a new ball game, completely different from the previous.
I wonder what happens to former KA slots at HKIA.
