TMK most of CA's 330s are leased from KA and, therefore, feature regional interiors (in the KA color scheme). However, around the time CA launched its SYD service, I read an article about it (probably in an in-flight mag) which had pictures of the airplanes they're using. My impressions were: nice looking seats and snazzy IFE* in all classes.

*It's worth noting that snazzy IFE often disappoints on Chinese airlines because the content is so bad. But, at minimum, you should get a map and a few video games, which is a lot more than most CA airplanes offer.
