I fly CX’s F class longhaul regularly and it is terrific. I have taken a good look at the J class and it looks narrow. Having said that, the YVR/HKG flight is a night one and you probably want to sleep ? It is flat but I don’t know what AC’s J class product is like ?
It is a pity CX’s Director Customer Service appears not to condescend to respond to posts on BT ? He never posted a reply to the threads on the lack of good arrival lounge facilities in LHR ?
BT – Can you press him to respond please ?
