Based on a few CAAC flights, a China Eastern, and a Sichuan Airlines flight, I would say they are better than the typical U.S. domestic coach experience.

You get a food service (but breakfast is usually rice gruel).

Hardware is newer.

Flight attendents are polite, not surly (Southwest and JetBlue excepted).

The CAAC attendents do a syncronized bow, which is pretty cool.

Most domestic flights are basically coach only, or have a few business class seats that I don't think FT people would think would rate as business class.
