Get your ticket at 3:30
You're sure to get there early (if the highway is jammed, there's nothing you can do! .....).
Take the bus: Tianhuan Passenger Terminal (Intersection of Hongqi Road and Anshan West Road, Nankai District, Tianjin, 87612376)
8:30 flight after 7:40 to get boarding passes .....
There is plenty of time, I was on a 7:45 departure time...
Don't worry about the time.
Make sure to find out if you're boarding in building 2 or 3 first ......
I'm not familiar with Fuzhou, but generally speaking, the airport buses are very obvious, so just ask the attendant when you get off the plane.
