Don Mueang International Airport, known as Bangkok International Airport before 2006, is one of two international airports serving Bangkok, the capital of Thailand, the other one being Suvarnabhumi Airport (BKK).

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.
