About TSA wait times at MSY

Louis Armstrong New Orleans International (MSY) sits about 15 miles west of the French Quarter in Kenner, Louisiana. It serves the New Orleans metro area and absorbs heavy seasonal spikes around Mardi Gras, Jazz Fest, and major Saints/Sugar Bowl weekends. The airport opened a brand-new consolidated terminal in late 2019 — the previous east terminal was decommissioned, and everything now operates from the new building.

The new terminal is a single linear concourse with three pier extensions — Concourse A, B, and C — and 35 gates total. There's one main TSA checkpoint feeding all three concourses, with a secondary checkpoint that opens during peak windows. Once you're past security, you can walk to any gate without re-clearing.

Because MSY's traffic is heavily leisure and event-driven, the airport's volume looks more like a tourist-airport rhythm than a typical midsize hub — Sunday-evening departures after a Saints game or Jazz Fest weekend can completely dwarf a normal Monday morning. Atlas's predictions account for event calendars and the live feed so you can plan around the day, not the week's average.

Frequently asked questions

When is MSY busiest?

Standard peaks are 5:00–7:00 AM and 4:00–7:00 PM Sundays. But MSY's real story is event-driven: Mardi Gras weekend, Jazz Fest weekend, and big Saints home games can completely reshape the airport's volume. Atlas's prediction reflects the specific date — a normal Sunday looks nothing like Mardi Gras Sunday.

How early should I arrive at New Orleans airport?

On a normal day, 75 minutes for domestic PreCheck and 90 for the standard lane is comfortable. Around Mardi Gras, Jazz Fest, or a major sports weekend, add 30–45 minutes — both checkpoints can be open with full lines. Atlas will give you a sharper prediction than these guidelines.

Does MSY have TSA PreCheck and CLEAR?

Yes — the main checkpoint has PreCheck lanes, and CLEAR is also available. The secondary checkpoint, when open, also has PreCheck. Atlas shows lane-by-lane predictions so you can pick the fastest path through.

What about parking at MSY?

The new terminal has a Short Term Garage and an Economy Garage right across the roadway, plus a Long Term Surface Lot served by shuttles. The garages are a real upgrade over the old terminal's lots — covered, fast access. On Mardi Gras weekend, even the long-term lots can fill, so pre-booking matters.

Are all the gates accessible after security?

Yes — Concourses A, B, and C all share the same airside, so once you're through TSA you can reach any gate without re-clearing. Concourse C is the longest walk if you're at the far end, but there are moving walkways through the connector.
