Louis Armstrong New Orleans International Airport (MSY) is owned by the City of New Orleans. While it serves as the primary commercial airport for the entire Southeast Louisiana region and 80% of the state's passengers, it is managed as a municipal asset. The day-to-day operations and strategic planning are overseen by the New Orleans Aviation Board (NOAB), which consists of nine members appointed by the Mayor of New Orleans. This ownership structure means that although the airport is physically located in Kenner, Jefferson Parish, it is the city's government that directs its capital improvements—such as the massive $1 billion "North Terminal" complex that opened in late 2019. In 2026, the airport continues to be a major economic driver for the city, operating as a self-sustaining entity that uses its own generated revenues and federal grants for development rather than relying on the city's general tax fund.
