I have never in 25 years of flying in the region found CX to excel in their offer, and they've had blunders all the time, anybody remembers the cow farm C class seats, the fixed backrest in Y, or the zodiac seat debacle? MPC devaluations?
Apart from the HKG lounges (when run by Peninsula) the worst thing ever happened was KA being taken over by CX. The level of service you consistently got on 3 hour flights was second to none, in F,C and Y class. The Elite was a great FFP, and the land based services were good too. Seats were so so, specially on night flights, but other than that, stepping on a KA flight was always something to look forward to (till the CX take over and its integration in MPC that is).
CX should bring back the KA teams if they really mean to become premium again. I never understood the hype with CX when compared to the early 2000's KA.
