So it seems like all the major Chinese airlines are joining the "big 3" international alliances.

On my upcoming trip, I'll be flying domestic flights on China Eastern (Skyteam) and Air China (Star). I hold "Elite Plus" status in Skyteam and "Gold" status in Star. As a practical matter, does this get me anything on these airlines?

I presume I have lounge access. But it's hard to get reliable lounge information. Skyteam doesn't list any China lounges in their directory. Star seems to indicate that Air China has lounges in (at the least) Beijing and Chengdu. Does anyone maintain, in English, a "master China lounge index"?

BTW, in Shanghai, I'm flying to Canada on AC. Is there a Star Alliance lounge there that makes sense to use?

Other than lounge access, do I get anything? I presume no upgrades, right? What about elite seating, or preboard? If I buy my ticket on ctrip or elong (I have no idea the fare class) will I earn ff miles? And will they actually post? I did call China Eastern on their USA phone number and put in my DL ff number. The agent seemed to know what to do. She said no advance seat assignments, however.

Thanks.
