Why Is New Orleans Airport Code MSY? The Origin Story

Your luggage tag says MSY and you are headed to New Orleans. Not NOL, not NOR — MSY. The code has nothing to do with the city name and everything to do with a stockyard that no longer exists.

What Does MSY Actually Stand For?

MSY stands for Moisant Stock Yards — the livestock market that once occupied the land where Louis Armstrong New Orleans International Airport now sits. The airport inherited both the land and the IATA code from the stockyard’s location. When three-letter codes were assigned, the Moisant area was how the site was identified, and MSY became permanent.

Who Was John Moisant?

John Bevins Moisant was an early aviation pioneer — a barnstormer and aircraft designer who gained fame in 1910 as the first person to fly across the English Channel with a passenger aboard. He was a showman and a competitor, participating in air races across the United States and Europe during aviation’s earliest years.

Moisant died on December 31, 1910, when his Bleriot monoplane crashed during an air race near New Orleans. He was 42 years old. The crash happened on the outskirts of the city, in the area that would later become the Moisant Stock Yards and eventually the airport. The Moisant family name became attached to the area, the stockyard carried it, and the airport inherited it.

From Stockyard to Airport

The Moisant Stock Yards operated on the site for decades before the land was repurposed for aviation. When New Orleans needed a new commercial airport in the 1940s, the Moisant area — flat, relatively undeveloped, and accessible from the city — was selected. The airport opened in 1946 as Moisant International Airport, later renamed New Orleans International Airport, and most recently renamed Louis Armstrong New Orleans International Airport in 2001.

Through three name changes, the IATA code never budged. MSY — from a stockyard named after an aviator who crashed nearby in 1910 — remains the permanent identifier for New Orleans air travel. It is one of the more unusual origin stories in American airport codes, connecting a livestock market, a pioneering aviator’s death, and a modern international airport through three letters that most passengers never think to question.
