The Airport Express line of the Beijing Subway also known as ABC (Airport Beijing City) is an elevated Metro line that connects the Beijing Capital International Airport (Beijing Capital Airport or Beijing Airport) with Beijing's urban center. The line is 28.1 kilometres (17.5 mi) in length and has only four stops: Dongzhimen and Sanyuanqiao in the city, and Terminal 2 and Terminal 3 of the Beijing Airport. The Airport Express line is designed to carry up to 4,500 passengers per hour at peak times and 40,000 passengers a day, with trains running for 15 hours a day with a minimum separation of four minutes between trains. The line entered into operation on July 19, 2008.

If you do have a lot of luggage, you might prefer to book a car or take a taxi, as the distance between interchanges in the subway is far. Its one major advantage is it avoids traffic jams which are common on Beijing's airport highway.
