MSY opened after World War II, replacing the older New Orleans Lakefront Airport (which kept the NEW and KNEW airport codes and now serves general aviation) as the city's main airport. MSY was renamed in 2001 after Louis Armstrong, a famous jazz musician from New Orleans.
Louis Armstrong New Orleans International Airport (IATA: MSY, ICAO: KMSY, FAA LID: MSY) is a public use airport in Jefferson Parish, Louisiana, United States. It is owned by the City of New Orleans and is located 10 nautical miles (19 km) west of its central business district. The airport's address is 900 Airline Drive in Kenner, Louisiana. A small portion of Runway 10/28 is located in unincorporated St. Charles Parish. Armstrong International is the primary commercial airport for the New Orleans metropolitan area and southeast Louisiana. The airport was formerly known as Moisant Field, and it is also known as Louis Armstrong International Airport and New Orleans International Airport.
Sitting at an average of 4.5 feet (1.4 m) above sea level, MSY is the 2nd lowest-lying international airport in the world, behind only Amsterdam's Schiphol International Airport in The Netherlands, which lies eleven feet below sea level (4.5 meters below Normaal Amsterdams Peil). Prior to Hurricane Katrina, MSY served 9.7 million passengers per year, nearly all of them non-connecting. In 2008, it served 7,944,397 passengers, representing an increase of 5.5% over the previous year. MSY has one of the best safety records among U.S. airports.
In February 2008, U.S. News And World Report ranked the travel experience at MSY 4th of the 47 busiest United States airports based upon the relatively small number of flight delays and frequently lower onboard flight loads.
Louis Armstrong New Orleans International Airport was once a major gateway for Latin American travel from the United States. That travel mostly goes through other cities which serve as hubs for international legacy airlines.
