This review is for Terminal 3 the international terminal. Beijing Airport is a pleasant and modern airport albeit one that feels a bit like a huge empty cavern. Free WiFi is available. However you need to register in person at the Business Center or a few other airport locations to get a user ID and PIN code that you then need to submit via a rather user- unfriendly web page. Apart from the cumbersome activation procedure I have no complaints about the WiFi service. The staff are generally polite and efficient despite their limited command of English. However there need to be more dining options within T3; currently there is little else aside from a Chinese Pizza Hut and a bunch of cafes. Overall it's a nice place for catching a flight but definitely not somewhere you'd want to linger for long at.
