What's the fastest way to get from Tianjin Airport to Beijing?

Hello,Ms.CF Bulos
Two options for you:
1)Direct bus from Tianjin Airport to Bawangfen. Fare: CNY35, Estimated journey time: 2.5h.
2)Taxi or public bus 666 from Tianjin Airport to Tianjin East Railway Station. Then Intercity train from Tianjin East to Beijing South. Estimated Fare with Taxi: CNY108, Estimated Fare with public bus: CNY60, Estimated journey time: 1h.

Thank you for the very helpful advice you gave. I arrived in Beijing using the Airport shuttle instead. Now, I need to return to Tianjin Binhai International Airport by the end of this week. What's the least complicated or the simplest way to get there from Beijing? How much time should I allot and how much money should I set aside for that? Many thanks in advance!
