Absurd. All of the points mentioned (except the rattling doors) are staff related, so they vary with the crew base and route. Sure the topology is different, but the 77A has other advantages (better air quality, for example) that the OP didn't mention or perhaps does not care about. However the BA forum has the same sort of diatribes about how bad F on BA 777 is compared to F on 747, so he is not alone in these viewpoints. The 747 does have a certain charm, but unless CX buys some 747-8's they have a limited life left.

I considered CX F to be the finest in the world for several years (say 2002-2006); this is no longer the case, and now does not make the top 5 -- yes, other airlines have improved so much, and CX has dropped a bit. Up to 2 years ago I saw systemic improvement at CX (every few months I would notice a change, often in mechanical or procedural aspects, and it was an improvement). Now CX seems to have lost their way (maybe some key staff left?), and the "improvements" are just changes, and as likely to be worse than what they replaced. Very sad. I guess the systemic improvement process has ended at CX.
