The first picture of the C cabin made me gasp with horror but the second one is much better. Certainly flyable and given CZ's reasonable pricing I might end up flying those more often. I'm not a fan of the really dense staggered layout though, I'd prefer 1-2-1 like SQ or 2-2-2 like KE/LH.
When CZ starts flying these birds across the Pacific I might try driving up to CAN to give it a try.
I love the fact that there's remote controls in Y. Some carrier which I have status on hasn't even made it to personal TVs on longhauls yet. (although I got one of the "premium" 777s with AVOD IFE on TPE-NRT yesterday, pretty nice!)
