Thanks badoc!
Really interesting to read your reports, especially as I have not travelled on QF long haul.
You are correct, CX does not have F on HKG-SYD, which I used in November. Pretty good J cabin, but not F, obviously.
Yes, OF, especially on the 777s, is showing its age and really needs to be replaced ASAP. I think this should happen in the not too distant future, hopefully....
