MSY Airport Terminal Guide: Layout, Security & Tips 2026

Louis Armstrong New Orleans International Airport is a single-terminal airport operated by the New Orleans Aviation Board, sitting about 11 miles west of downtown New Orleans via I-10. This MSY airport terminal guide covers everything you need to navigate the 2019 Main Terminal confidently — from concourses and security lanes to parking rates starting at $8.95/day off-site. Whether you're checking in at Concourse A or catching a Southwest flight from Concourse C, the layout is straightforward once you know the basics.

• Single main terminal opened November 2019, replacing the old facility.
• Three concourses — A, B, and C — serve all domestic and international routes.
• Security opens at 3:30 AM; TSA PreCheck and CLEAR lanes are available.
• Arrive 2 hours early for domestic flights, 3 hours for international.
• Off-site parking from $8.95/day — significantly cheaper than on-airport Short Term at $26/day.
• Economy Garage costs $12/day with a free 24/7 shuttle to Baggage Claim Door 9.

Before you park, compare MSY parking options from $8.95/day on Triply — rates and shuttle schedules vary by lot, and locking in a price now saves money at the airport gate.

MSY Airport Terminal Guide: The Basic Layout

MSY's Main Terminal is a single building with all check-in, security, gates, dining, and baggage claim under one roof. It opened in November 2019 and replaced an older facility on the south side of the property. The official MSY facility maps show the full layout, but here's what you actually need to know before you arrive.

Levels at a Glance

• Level 1 — Arrivals and Ground Transportation: Baggage claim carousels, rideshare and taxi pickup, hotel shuttle pickup at the Ground Transportation Center (Baggage Claim Doors 1-5 / B5), and the Economy Garage shuttle drop-off at Door 9.
• Level 2 — Departures and Security: Airline check-in counters, TSA checkpoints, and the entrance to all three concourses.

The Three Concourses

Once through security on Level 2, you'll walk into one of three concourses. Concourse A is the first you reach from the checkpoint. Concourse B extends from there and handles much of the traffic for major legacy carriers. Concourse C sits at the far end and is the home base for Southwest Airlines, MSY's largest carrier by seat share. All three are connected airside, so you don't need to re-clear security if your gate changes.

Airlines at MSY (verified October 2026)

According to the official MSY airlines page, the following carriers currently serve the terminal:

• Air Canada
• Alaska Airlines
• Allegiant Air
• American Airlines
• Breeze Airways
• British Airways
• Delta Air Lines
• Frontier Airlines
• JetBlue
• Southwest Airlines
• Sun Country Airlines
• United Airlines

British Airways serves the only transatlantic route from MSY. If you're on that flight, add extra time for international check-in and departure formalities. Per Bureau of Transportation Statistics data, Southwest has consistently held the largest share of seats at MSY in recent years.

Security at MSY: Hours, Lanes, and Wait Times

MSY's security checkpoint on Level 2 opens at 3:30 AM daily. That's earlier than many mid-size airports, which helps travelers on early morning departures. According to MSY's security checkpoint page, the airport offers both standard TSA lanes and dedicated lanes for expedited travelers.

TSA PreCheck and CLEAR at MSY

TSA PreCheck lanes are available at MSY. PreCheck members keep laptops and liquids in their bags and don't remove shoes — this typically cuts screening time significantly. If you're not enrolled yet, PreCheck is worth it for frequent travelers.

The CLEAR biometric screening program is also available at MSY. CLEAR uses fingerprint or iris scan to verify your identity, letting you skip the ID check line and jump straight to the physical screening lane. CLEAR works best when paired with PreCheck — you verify your identity with CLEAR, then use the PreCheck lane for the actual X-ray process.

How Long Will Security Take?

Wait times at MSY are generally shorter than at major hub airports, but they spike during Mardi Gras, Jazz Fest, and Saints home games — all of which flood New Orleans with visitors who tend to fly out on the same days. Check live data at TSA Wait Times before you leave for the airport. For general TSA security screening guidelines, the official TSA site is the definitive source.

Follow these TSA's official screening rules to avoid delays at the checkpoint:

• Remove all liquids and gels from your carry-on and place them in a quart-size bag.
• Take laptops out of their cases and put them in a separate bin.
• Remove jackets, belts, and shoes (unless you have PreCheck).
• Be ready to show your boarding pass and ID before the conveyor belt.

How Early Should You Arrive at MSY?

For domestic flights, plan to be at the airport at least 2 hours before departure. For international flights (including the British Airways transatlantic route), give yourself 3 hours. These windows assume normal security wait times — add buffer during major New Orleans events.

Factor In Your Parking or Shuttle Time

Your total arrival window depends on where you park. Here's how each option adds time to your morning:

• Short Term, Long Term, or Surface Lot: Walk directly to the terminal — no shuttle time needed. Add 5-10 minutes to find your space and walk to Level 2.
• Economy Garage (900 Airline Drive): The free 24/7 shuttle runs to Baggage Claim Door 9 with a 15-minute ride guarantee. Add at least 20-25 minutes from the time you park to reaching the check-in counters on Level 2.
• Off-site hotel lots (Hilton New Orleans Airport): The Hilton's free shuttle runs every 15 minutes, 24/7. Add 20-30 minutes total from parking to check-in.
• Comfort Inn New Orleans Airport South: Shuttle runs on demand, but only 6-11 AM and 5-11 PM. If your flight departs mid-day, you'll need a rideshare. Plan accordingly.
• DoubleTree New Orleans Airport: No shuttle — you'll book an Uber or Lyft. Add 10-15 minutes for rideshare arrival plus the drive.

For the full breakdown of shuttle schedules and pickup locations, the MSY park and fly hotels guide covers each hotel's exact shuttle rules side by side.

A Practical Departure Walkthrough

1. Park and note your space — take a photo of the level and row number.
2. Board the shuttle or walk to the terminal — Economy Garage riders go to Level 1 of the garage for pickup.
3. Enter on Level 2 via the departures curb and check in at your airline counter or kiosks.
4. Clear security — PreCheck and CLEAR lanes open at 3:30 AM.
5. Head to your concourse — A is closest, C is farthest. Allow a few extra minutes if you're at the far end of Concourse C.

MSY Airport Terminal Guide: Parking Options and Rates (2026)

Parking at MSY ranges from $8.95/day off-site to $36/day for valet on-airport — a difference of more than 75% between the cheapest and most expensive options. All on-airport facilities accept credit card only, per published rates on flymsy.com (verified October 2026).

The Economy Garage holds 2,438 spaces at 900 Airline Drive in Kenner — the former long-term garage at the old terminal. It's the cheapest on-airport option at $12/day, but it's a remote lot. The free shuttle runs 24/7 to the far curb outside Baggage Claim Door 9. If the ride takes longer than 15 minutes, you get a 50%-off parking voucher at exit. You can track the shuttle in the Ride Systems app.

For a deeper look at where each lot sits on the airport campus and how the billing works by the half hour, see the MSY parking map and lot guide, which walks through road access, EV charging, and accessible parking locations for every facility.

Reserving Your Spot

All on-airport facilities accept reservations at park.flymsy.com. A few things to know before you book: reservations are non-refundable if canceled, and no changes are allowed within 24 hours. You must enter within two hours of your reserved time. When you arrive, scan the QR code from your confirmation email — do not pull a ticket or you'll be charged twice.

Ground Transportation: Getting In and Out

All ground transportation pickup at MSY happens on Level 1. The setup is straightforward: hotel and lot shuttles use the Ground Transportation Center at Baggage Claim Doors 1-5 (B5), while rideshare and taxis have separate designated areas.

• Rideshare (Uber/Lyft): Pick up at the designated rideshare zone on Level 1. Check the Uber MSY page for exact pickup instructions.
• Taxis: Available at the taxi stand on Level 1. See the MSY taxis page for current fare information.
• Hotel/lot shuttles: Wait at the Ground Transportation Center — your shuttle driver will call out the hotel name.
• Public bus: The RTA Airport Express (Route 202) runs to downtown New Orleans (Elk Place / Union Passenger Terminal). The JET Veterans-Airport (E1) connects the airport to City Park Avenue. See norta.com for RTA schedules and jptransit.org for JET routes.
• Car rentals: The Rental Car Center is on Rental Boulevard. A shuttle connects it to the terminal. See the MSY car rentals page for participating companies.

For step-by-step instructions on each of these options — including bus fares, taxi flat rates, and rideshare pickup zones — the getting to and from MSY airport guide covers each mode in depth.

What's Happening With MSY Expansion in 2026?

MSY is in active planning and construction phases as of late 2026. No parking facilities are closed, but travelers should know what's in progress. A ~$45 million baggage explosive-detection system upgrade is targeting completion in late 2026. A ~$52 million shuttle-only road connecting the current terminal to the old south terminal area is in its first phase. Airport officials stated in July 2025 that long-range growth will require approximately 15 new gates and a new parking garage by around 2031, currently in the planning stage.

None of these projects create traveler-facing parking disruptions right now. Check flymsy.com for current alerts before your trip. If traffic on I-10 near the Loyola Drive flyover ramp concerns you, check real-time traffic on Waze before you leave home.
