Just flew VH-OQK back from LAX (QF12). As it was a night flight, there weren't many people going up there, of the ones that did it was mainly individuals rather than couples or groups, so not noisy at all. The curtain between the mini cabin and bar area did a good job of blocking out light and noise.
A few interesting things I observed on the refurbished aircraft was that the moving map and 'time until arrival' countdown weren't showing/operating, as well as no access to the aircraft exterior cameras; minor little things, I know. Also, the remote for the screen in the bar/lounge area has been moved inside one of the cupboards, unlike on the unrefurbished aircraft where its beside the red couch. Was not allowed to play 'Who wants to be a millionaire' on the big screen (Woe is me
).
