Hannover Airport is the international airport of Hanover, capital of the German state of Lower Saxony. The ninth largest airport in Germany, it is situated on 570 hectares in Langenhagen, 11 kilometres (6.8 mi) north of the centre of Hanover. The airport has flights to European metropolitan and leisure destinations, and serves as a base for Eurowings, Corendon Airlines Europe and TUI fly Deutschland.

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.
