Flew last month with CX LAX-HKG-BKK on 744s the whole way - leapt off the aircraft and went right out with friends...crew were extremely attentive, food was good, snacks mid-flight very tasty, and we were bang on-time. Fantastic. Can't wait to fly with them again. LAX-HKG was 14 hrs 29 mins wheels up to touchdown, but AVOD really helped get through it!
Transit at HKG very easy. 45 mins enough, but try and get some time in the lounge if you can get a longer connection. Either The Wing or The Pier (by gates 64/66, I think?) are great!
Have a great trip!
