Regarding CX, not sure if it's new, but I noticed during my recent flights, all the FAs addressing OWEs (assume CX DMs also) by name. I was taken aback when the FA near the door uttered, "Bye bye, Mr. V." This was J, not F.

I don't recall any OWE recognition on any other carrier, and certainly not AA, AS or BA. Maybe on JL, but I really can't recall. My most recent JL flight, there was no recognition.
