Jazz, food & festivals — and Southwest keeps the flights affordable
Louis Armstrong International (MSY) is a leisure-driven airport where Southwest runs a large operation alongside Spirit, Frontier, and the legacy carriers. Because New Orleans is a pure destination market, airlines discount heavily outside of festival season — but Mardi Gras, Jazz Fest, and big football weekends send fares soaring. Time your trip around the calendar and sub-$130 roundtrips from much of the country are common.
Late August through November and the summer heat of July deliver the lowest fares. Avoid Mardi Gras (Feb/Mar), Jazz Fest (late April-May), and Sugar Bowl week.

When are flights to New Orleans cheapest?
Late August through November and the height of summer (July) are the cheapest, with roundtrip fares from the East and Midwest dropping to $90-140. Avoid Mardi Gras and Jazz Fest, when both flights and hotels can triple in price.
Which airlines fly cheapest to New Orleans?
Southwest has the biggest presence at MSY and runs frequent sales, making it the top choice for low fares. Spirit and Frontier offer rock-bottom base fares on select routes, while American, Delta, and United provide additional competition that keeps prices in check.
How far ahead should I book for Mardi Gras or Jazz Fest?
Book at least 3-6 months ahead for major festivals. Demand for Mardi Gras and Jazz Fest is enormous, and cheap inventory disappears fast. For any other time of year, you can usually wait for a Southwest or budget-carrier sale and still get a great fare.
