How to get Kunming Jinjiang Hotel from airport by subway ?

If you take the subway from the airport, you will only reach the East Bus Station. Then you need to transfer to bus line T1 to reach Juhua Village (Ju Hua Cun) Station and then change to bus line Z12 to reach KM Railway Station.
After that you can walk along Beijing Road to your hotel.

As I know, you can also take the airport shuttle bus line 2 to reach Jinjiang Hotel directly. A bus station for shuttle bus line 2 is called Jinjiang Hotel.
