high speed train from and to kunming

Up to now, there is no high speed rail service in Kunming.

Can you tell me the website to buy domestic airplane tickets ?

Actually I plan a trip from Jakarta To Kunming but I want to go to another city too, because I want to stay 1 week in China, but doesn't want to spend all 1 week time only in Kunming..

Do you have any recommendation which city I should go?

Thanks
