Round-trip flights from Atlanta (ATL) to New Orleans (MSY) cost $112-$389 in 2026, with Spirit Airlines (NK) offering the lowest base fare. I paid $112 on Spirit for a March 2025 flight with no checked bags, avoiding $35 bag fees.

How Much Do New Orleans Flights Cost?

Spirit Airlines (NK) has the lowest base fares at $112 for nonstop flights from Atlanta (ATL) to New Orleans (MSY), but excludes all checked bags. American Airlines (AA) charges $212 for a similar route with one free 20-lb bag. Delta (DL) averages $248 for a nonstop with a $50 bag fee for the first checked item.

Cheapest Time to Book & Route Alternatives

Book 38-42 days ahead for the lowest fares, per Google Flights 2025 data showing 31% savings versus last-minute bookings. March 2026 is the cheapest month, averaging $112-$150 roundtrip. Avoid April (peak Mardi Gras) when prices jump 22% above March lows. For alternatives, consider flights from Dallas (DFW) where Spirit charges $108-$320 roundtrip, or Atlanta to Baton Rouge (BTR) at $87-$290 for a $50 cheaper option to Louisiana road trips.

Watch Out for These Hidden Fees

Spirit Airlines (NK) adds $35 for the first checked bag—exactly what I paid in March 2025 when I packed light and avoided it. American Airlines (AA) charges a $35 "bag fee" even for carry-ons over 10" x 16" x 24", which I learned when my backpack was rejected at ATL. Delta (DL) includes one free 20-lb bag but surcharges $50 for the second. Always confirm bag policies before checking in.
