Wilmington International Airport is a public airport located just north of Wilmington, North Carolina, in unincorporated Wrightsboro. ILM covers 1,800 acres.

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.
