Louis Armstrong New Orleans International Airport (MSY) serves New Orleans, Louisiana, and lies about 11 miles from the city center. The airport sits at an elevation of just 4 feet above sea level, among the lowest elevations of any major airport, which reflects the flat, low-lying coastal geography of the region.

Traffic at MSY is predominantly domestic, connecting New Orleans with other major cities across the United States, including destinations along the Gulf Coast, the West Coast, and other regions of the country. The route pattern points to a hub that primarily serves point-to-point domestic travel rather than functioning as an international gateway, with flights linking New Orleans to both nearby regional centers and cities much farther afield.

Given its low elevation and location near the Gulf Coast, travelers should be aware that the airport's setting can be associated with regional weather patterns typical of the area, including humidity and coastal storm systems that can develop during certain seasons. Flyers connecting through MSY on domestic routes should expect typical continental weather variability depending on the season and the regions being connected to New Orleans.
