Maybe I am missing something obvious but I can't seem to find Tengchong airport on any flight search engine. Baoshan seems reasonably close but it would still take a long busride to get from there to Tengchong. Is the new airport there open yet and if so, does anyone know which airlines fly to there from Kunming? I read somewhere that China Eastern is operating on that route but at their website there is no mentioning of Tengchong at all.

As far as I know, its open, but not officially
They have some flights, but only China Eastern.

The official opening is going to be in May, than flights should increase an prices should drop. (I got the information from local Cabdrivers in Tengchong, I hope its correct). Try to book using an China Eastern office or maybe even a travelagent.

Tengchong is great, I stayed at the hostel, which is brand new and definitely worth the money!
