Terminal 1 hosts 8 airlines across 22 gates.
22 gates in one modern terminal at MSY
The single terminal at Louis Armstrong New Orleans International Airport (MSY) holds 22 gates under one roof, so you’re not bouncing between buildings or shuttle buses once you’re inside. Every airline listed for MSY’s main operations runs out of this terminal, which keeps walking times reasonable even when you land at one end and depart from the other.
American Airlines, Delta Air Lines, Southwest Airlines, United Airlines, Alaska Airlines, Frontier Airlines, JetBlue Airways, and Spirit Airlines all use this same terminal, so domestic connections stay airside as long as both flights are on these carriers. With one security checkpoint feeding into the terminal, your main time variable is the TSA line, not inter-terminal transfers.
MSY labels this facility as Terminal 1, and all 22 gates feed from a central concourse layout. That means you pass through a single security zone and then walk out toward your gate rather than choosing a terminal first. Signage points you directly to the numbered gates, so once you know your gate number from the app or display boards, you just follow the sequence.
On the food front, no specific restaurants are catalogued here, so plan as if your options may be limited or clustered near the central area instead of every individual gate. With 22 gates serving airlines like Southwest and Spirit that board quickly, it’s smart to eat or stock up on snacks before you settle at a far-end gate where choices may thin out.
No airline or independent lounges are listed for this MSY terminal, so don’t count on lounge access for a long layover with American, Delta, United, or any of the other six airlines here. If you typically rely on a lounge for power outlets and quieter seating, pad your schedule to grab a seat early at the gate and charge devices from the standard gate-area outlets instead.
Shops also aren’t catalogued for this terminal, so assume only basic airport retail rather than deep duty-free or specialty options. If you need something specific or higher-end, buy it in town before heading to MSY’s Terminal 1, or plan to use whatever limited options sit near the central concourse rather than expecting every gate cluster to have a store.
One practical tip: with everything set inside this single Terminal 1, check your gate number in your airline app before you clear security, then pick a security lane closest to the approximate gate range to cut down on backtracking across the 22-gate concourse once you’re inside.
