China has created a comprehensive transportation system of railways, highways, and airports, that is ever expanding. International flights from second tier "visa-free transit" cities, High-Speed Rail, and city underground systems are the latest China transport phenomena.
There are two cities in China that have two airports: Beijing (Capital International Airpot and Nanyuan Airport) and Shanghai (Pudong International Airport and Hongqiao International Airport). If you choose to board a plane by yourself, please make sure of your flight information: departure time, flight terminal and airport.
