Airport Shuttle from GZ East Railway to Baiyan Airport

there is shuttle bus from the railway station to the airport, but you can take the subway line 3 (north branch) from the railway station to the airport. you will find clear signs of the subway station.
the first oen heading to the airport at 06:15. it costs CNY 11 per person.

I need to be at the airport early for a flight at 06h45 so the metro is not an option. And I live close to the Railway Station so would rather take the shuttle if I can. Where does it leave from at the Station?

there is no direct shuttle bus from the railway station to the airport. the nearest airport shuttle bus station is about 1.4 km from the railway station, plus the first bus departs at around 6am fromt the station, so you can not catch your flight by the bus. i suggest that you take a taxi to the airport. since you start off early in the morning, you may book one in advance.
