Beijing Capital International Airport is the main international airport of Beijing, China. It is located 32 km northeast of Beijing’s city center in an enclave of Chaoyang District that is surrounded by rural Shunyi District. The airport is owned and operated by the Beijing Capital International Airport Company Limited, a state-controlled company. The airport’s IATA Airport Code, PEK, is based on the city’s former romanized name, Peking.
