I wish to book a China Southern domestic plane tickets from Kashi (KHG) to Beijing on 8 April 2014.

On 8 April a China Southern goes from Kashi to Urumqi at 10.15 (flight CZ 6812) and then on to Beijing at 13.10 (CZ 6932) arriving Beijing at 16.35. This is the flight I need but your website is giving me only one option - and that is a later Air China flight which is too late. Is it possible to get a price for the China Southern flight I wish to take? thank you.
