Yes, I flew CX
last year in November from MEL
, they had excellent service, the crew's were friendly and professional and generally pleasant, aircraft were spotless. In flight entertainment was good, wide choice of films and shows were available. Leg room was terrible but I am quite tall. Food I found quite dissapointing, bland and tasteless (unusal for an Asian airline). Nice ammenity kit for all Y passengers, (Eyeshades, socks- I think and a mini-toothbrush with toothpaste)
I would rate them on par with Singapore Airlines, Malaysia Airlines etc. You should enjoy them to London, just make sure to try and get an exit row if you are on the tall side otherwise you can enjoy your legs being crushed.
