Dear Miguel a Oviedo,
Greetings from Top China Travel! :-)
Regarding the international flight ticket booking, I am afraid we could not get a so good price. If you will travel from LA to Changchun, I think if possible, you can inquiry the local airlines or check on line. You may grab a nice discount rate.
But it will be our pleasure to arrange the tour/transfer service in Changchun or other cities in China for you if necessary.
If you have any further inquiry or question, please feel free to contact with us.
Kind regards,
Zoe
