Denver International Airport (IATA: DEN, ICAO: KDEN, FAA LID: DEN), often called DIA, is, by land size, the largest international airport in the United States, and the third largest international airport in the world, after only King Fahd International Airport, and Montreal-Mirabel International Airport.
Currently, Denver International Airport is the fifth busiest airport in the United States in terms of traffic, and the tenth in the world with 47,324,844 passengers passing through the airport in 2006; a 9.1% change from 2005.
