I got that the airfare for the flight CA983, departing at 21:00 from Beijing and arriving at Los angeles at 18:00(local time) is about USD743 including the tax, which is just for your referrence. Personally, it is better for you to consult some booking agencies for the details directly.

We are interested to attend the CHINA ASEAN EXPO this coming nov19-22. Please send us information about the flight from manila Philippines to Nanning Guangxi China (vice versa). Do they still have the same flights in the ones you wrote here?

There are no direct flights from Manila to Nanning, only some connecting flights with transfers at Beijing, Shanghai, Guangzhou and etc. It would cost less flight time to transfer at Guangzhou and the flights are provided by China Southern Airlines. About the flight info. and ticket price, you could make an online inquiry or consult some local travel agencies.
