MSY · Louis Armstrong New Orleans International Airport

Overview

Louis Armstrong New Orleans International Airport (MSY) is the principal commercial airport serving New Orleans, Louisiana, and the surrounding South region. Ranked number 41 on the most recent list of the busiest airports in the United States, it handled approximately 13.3M passengers in its last reported year, placing it firmly among the country's most consequential aviation gateways. The airfield operates 2 active runways and presents travelers with 1 passenger terminal, organized into a layout that has been refined across decades of capital improvement programs and changing carrier strategies.

For most arriving travelers, the first impression of New Orleans is shaped here. The airport functions as a hub for Southwest Airlines, which means a substantial share of the traffic on the field consists of connecting passengers who never leave the secure side of the building. That dynamic affects everything from how the concourses are laid out to how long the security lines run during the morning and late-afternoon banks. Understanding which airline you are flying and which terminal it uses is the single most useful piece of information for navigating MSY smoothly, because the journey between terminals can range from a short walk to a dedicated train ride depending on the configuration.

Beyond raw passenger counts, Louis Armstrong New Orleans International Airport plays an outsized role in the local economy. Tens of thousands of jobs — from ramp agents and TSA officers to chefs, retail workers, and corporate aviation staff — are tied directly to operations on the field, and the surrounding cargo, logistics, and hospitality industries that orbit the airport employ many thousands more. Concession programs have also shifted in recent years toward locally owned restaurants and regional brands, so the food and shopping you encounter inside the terminals are increasingly an extension of the New Orleans dining and retail scene rather than the generic chain-store airport experience of an earlier era.

This guide is organized into focused sections so that you can jump straight to the information you need.
