I need to go from Tianjin to Beijing international airport. Please advise alighting station, subway line number, journey time and cost. And how's about from Liangma Qiao station to take high speed tr

Hi, go to local Tianhuan Bus Station to take a direct bus to Beijing International Airport and it takes around 2.5h. The bus fare is CNY82 per person.

As for the high speed train, I wonder whether you refer to Beijng Airport Express Train. If yes, you can take subway line 10 at this station to Sanyuanqiao to transfer to the express train to the airport.
