Louis Armstrong New Orleans International Airport (IATA: MSY, ICAO: KMSY, FAA LID: MSY), formerly known as Moisant Field, while other names for it are Louis Armstrong International Airport and New Orleans International Airport, is located at 900 Airline Drive, Kenner, Louisiana and is the primary commercial airport for the New Orleans metropolitan area and of southeast Louisiana. Sitting at an average of 4.5 feet (1.4 m) above sea level, MSY is the second lowest lying international airport in the world, second only to Schiphol International Airport in The Netherlands, which sits at 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. Back 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 few flight delays and lower 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. It 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. The airport was renamed in 2001 after Louis Armstrong, a famous jazz musician from New Orleans. The National Weather Service forecast office for the area moved to the suburb of Slidell, and now uses non-airport codes LIX and KLIX.
MSY is owned by the City of New Orleans (Orleans Parish), but is primarily located in the city of Kenner, which is in neighboring Jefferson Parish. A small portion of the longest runway is located in unincorporated Saint Charles Parish.
