Southwest at MSY: terminal and gate information

MSY’s own airline information also places Southwest in Concourse B. Airport and airline gate assignments can change, so the live departure display controls on your travel day.

Where should Southwest passengers check in?

Use the Southwest ticket counter or self-service facilities in the main terminal when you need to check bags or complete in-person check-in. Passengers with a boarding pass and no checked bag can proceed toward security, subject to any document or international-travel requirements.

Southwest publishes variable ticket-counter opening times by day at MSY. Those times can change, so check the airline’s current airport-information page rather than relying on a saved screenshot.

How early should you arrive at MSY?

Southwest currently suggests arriving:

• 90 minutes before a domestic departure; and
• 120 minutes before an international departure.

These are suggested arrival times, not guarantees. Add time for checked bags, parking, rental-car return, accessibility assistance, holidays and major New Orleans events. Check current TSA wait information and your flight status before leaving.

How to reach Concourse B

1. Enter the main passenger terminal at 1 Terminal Drive.
2. Complete Southwest check-in or bag drop if required.
3. Follow airport signs to passenger screening.
4. After screening, follow signs for Concourse B.
5. Confirm the gate on the airport display or Southwest app before walking to it.

You do not need to transfer to a separate off-site Southwest terminal. Concourse B is part of MSY’s main terminal complex.

Does Southwest always use the same MSY gate?

No. The airline currently lists a group of Concourse B gates rather than one permanent gate for every flight. Operational needs, delays and schedule changes can move a departure within the concourse or, occasionally, elsewhere.

Use the gate shown for your specific flight. A general airport guide cannot replace live flight information.

MSY amenities relevant to Southwest passengers

Southwest lists airport-provided Wi-Fi, charging stations, self-tagging, priority and express lanes, and TSA PreCheck Touchless ID among the amenities available at MSY. Eligibility and operating availability vary.

For current restaurants, shops, accessibility services and terminal maps, use the official MSY Getting Around page. Concession names and hours change more frequently than concourse assignments, so this page does not reproduce a potentially stale restaurant list.
