Shanghai Hongqiao International Airport is one of two international airports of Shanghai, the largest city by population in China, and a significant airline hub of the country. Hongqiao Airport mainly serves domestic and regional flights, although the airport also serves select international flights. The airport is located near the town of Hongqiao in the outskirts of Changning and Minhang districts, 13 kilometres (8.1 mi) west of downtown, and is closer to the city center than the area's primary international airport, Shanghai–Pudong.

An IATA airport code, also known as an IATA location identifier, IATA station code, or simply a location identifier, is a three-letter geocode designating many airports and metropolitan areas around the world, defined by the International Air Transport Association (IATA). The characters prominently displayed on baggage tags attached at airport check-in desks are an example of a way these codes are used.
