Folks , I found the holy grail for consistent Inflight Service on CX! (and it is not being a DM)

As Gold member seated next to the wife of the CX Head of Flight Operations, I saw the best service ever given to her. As a loyal revenue passenger, I was completely ignored. The ISM met her at the door, took her bags , made sure her VGML was correct, champaign for her and priority disembarkation on arrival.

So the best way to ensure consistent service is to be a) wife of the chief pilot, b) be the chief pilot.

Then again, Kudos still to CX for their efforts in the cabin. ( TG's Royal Service ends at the Gate. Thai FAs completely disregard their loyal Gold members in the cabin )
