I have just flown CX Y LAX-HKG ( daytime 15 hours) and a few days later HKG - ADL (8 hour night flight). Having just completed LONE including QF, BA and AA sectors CX seats were by far the most uncomfortable for both day and night flights. I am 163cm and from previous reviews thought I would cope with these seats - WRONG!! DO NOT FLY CX Y until these seats change!!
Also compared to BA, QF, and AA service was terrible and state of toilets was disgusting with no toilet paper after a couple of hours into the flight and puddles of urine all over the floor. Thumbs down to CX Y from me.:evil:
