Booking a flight to MSY is a weird experience. One minute you’re looking at a $140 round-trip from Chicago, and then you blink, and suddenly the "basic economy" upcharges have pushed it to $300 before you've even picked a seat. It's frustrating. Honestly, cheap airfare to New Orleans isn't some mythical creature, but the way airlines price tickets into Louis Armstrong International Airport follows a logic that feels borderline chaotic if you don't know the rhythm of the city.
New Orleans is a destination driven by events. If there’s a massive convention or a festival you’ve never heard of, prices spike. I’ve seen people try to book a "random weekend in October" only to realize they accidentally picked the weekend of the Voodoo Music + Arts Experience or a massive cardiology conference that sucked up every hotel room and flight seat in the Southeast.
Why Your "Cheap" Flight Might Actually Be Expensive
Most people start their search on a big aggregator. You see a low number, you click, you feel a small win. But MSY is a major hub for Spirit and Southwest, which means the "sticker price" is almost never what you pay.
Let's talk about the Spirit trap. They fly into New Orleans from dozens of cities. If you’re coming from LAX or DFW, you might see a $60 fare. But by the time you pay for a carry-on—which often costs more than the seat—and a soda, you’re at $180. Meanwhile, Southwest flies into New Orleans with two free checked bags. If you’re heading down for a wedding or a festival where you need actual outfits (and not just a backpack), Southwest is often the "stealth" winner for cheap airfare to New Orleans, even if the search engine says otherwise.

The airport itself is relatively new. The "new" MSY terminal opened in late 2019, and it’s beautiful, but it changed the logistics. It’s further from the city center than the old one in terms of walking time from the gate to the curb. Factor in the $36+ flat rate for a taxi or the surge pricing on Uber, and that "cheap" $90 flight just cost you another $100 in ground transport.
The Tuesday Myth and the 45-Day Window
You’ve heard the advice: book on a Tuesday at 3:00 AM.
That’s mostly garbage now.
Modern airline algorithms are way more sophisticated than a simple weekly reset. However, there is a specific cadence for New Orleans. Because the city relies so heavily on weekend tourism, flight prices for Friday arrivals and Monday departures are consistently the highest in the region. If you can shift your "weekend" to a Thursday–Sunday or a Saturday–Tuesday, the price drop is often staggering. Sometimes as much as 40%.
Data from travel aggregators like Hopper and Google Flights suggests that for domestic flights to MSY, the "sweet spot" is usually 3 to 6 weeks out. But there’s a catch. New Orleans has a "high season" that lasts from February (Mardi Gras) through May (Jazz Fest). During this window, that 45-day rule goes out the window. If you see a price you can live with for Jazz Fest in January, buy it. It won't go down.
Watching the "Shoulder" Months
August in New Orleans is hot. It is "melt-into-the-sidewalk" hot. It’s also when you find the absolute cheapest airfare.
If you can handle the humidity, August and September offer the best deals. Airlines struggle to fill planes when the heat index is 105 degrees. But there’s a secondary benefit: COOLINARY. This is a city-wide event where the best restaurants in the world (Commander’s Palace, Galatoire's) offer fixed-price lunch and dinner menus for a fraction of their usual cost. You save $200 on the flight and another $200 on food. It’s a trade-off. Some people hate the heat; others see it as a fair price for a five-star meal and a cheap seat.

The "Alternate Airport" Gamble
Sometimes, cheap airfare to New Orleans isn't actually to New Orleans.
Baton Rouge (BTR) is about 90 minutes away. Gulfport-Biloxi (GPT) is about an hour and fifteen minutes. Occasionally, a legacy carrier like United or Delta will have a massive sale into Baton Rouge because they’re trying to compete with a regional route.
Is it worth it? Usually, no.
By the time you rent a car and pay for gas, you’ve spent the savings. The only exception is if you’re traveling in a group of four. Splitting a rental car from Gulfport can sometimes save a family $400 over flying directly into MSY. Plus, the drive from Gulfport across the Twin Spans over Lake Pontchartrain is one of the most beautiful entries into any American city. You see the skyline rising out of the water. It's spectacular.
What Most People Get Wrong About Mardi Gras Flights
Every year, someone tries to book a "last minute" flight to Mardi Gras.
Don't.
If you aren't booking your Mardi Gras flight by November, you aren't getting cheap airfare to New Orleans. You're getting whatever is left. The secret, though, is flying on Mardi Gras Day. Most people want to be there for the weekend leading up to "Fat Tuesday." If you fly in on Tuesday afternoon or Wednesday morning, the prices crater. The party isn't over; the locals are just starting to relax, and the city stays "purple, green, and gold" for another week.
A Real-World Example: The "Price Match" Trick
I recently helped a friend look for flights from NYC to New Orleans.
- JetBlue was $310.
- Delta was $345.
- Spirit was $115.
On paper, Spirit wins. But my friend had a carry-on and wanted a specific seat. Spirit’s fees brought that $115 up to $265. For a $45 difference, he chose JetBlue for the extra legroom and free Wi-Fi.
The lesson? Always go to the "final" checkout page before you decide which flight is actually the cheapest. The "teaser" rates are designed to get you into the funnel.
Actionable Steps for Your Next Booking
Don't just keep refreshing the page. That does nothing but stress you out. If you want the best possible price, follow this specific sequence:
1. Set a "Price Track" on Google Flights immediately. Don't wait until you're ready to buy. Set it for your specific dates and an "anytime" window. You'll get an email the second the airline's revenue management software twitches.

2. Check Southwest separately. Southwest does not show up on Expedia, Kayak, or Google Flights. You have to go to their site. Frequently, their "Wanna Get Away" fares are $20–$50 cheaper than the lowest "Basic Economy" fare on other airlines once you factor in the bags.
3. Use the "Multi-City" tool for Jazz Fest. If you’re coming for a festival, try flying into New Orleans and flying out of Baton Rouge or even Houston if you’re planning a road trip. It sounds crazy, but "open-jaw" tickets can sometimes bypass the massive price spikes that happen when everyone tries to leave MSY on the same Monday morning.
4. Join the "Spirit Saver$ Club" if you travel frequently. If you fly to New Orleans more than twice a year from a Spirit hub (like Fort Lauderdale or Detroit), the $69 annual fee usually pays for itself in a single round trip through "member-only" fares that aren't visible to the general public.
5. Avoid the "Big Event" surge. Check the New Orleans Convention and Visitors Bureau (NewOrleans.com) calendar. If there is a "City-Wide" event listed, expect flights to be double the normal rate. If your dates are flexible, move your trip by just three days to avoid the 20,000 people arriving for a dental convention.
New Orleans is a city that rewards the savvy and punishes the impulsive. The money you save by being smart with your airfare is money you can spend on a second round of oysters at Casamento's or a better view of the French Quarter. Stay disciplined with your search, watch the hidden fees, and never assume the first price you see is the real one.
