Historical odds, not a guarantee. Built from the US DOT Bureau of Transportation Statistics on-time reports (Jun 2025 to May 2026), FAA ground stop and delay program advisories, and 20 years of airport weather observations.

LAX to MSY questions

What time of day is best to fly LAX to MSY?
Before 9 AM: 89% of flights arrived on time, against 68% for departures noon to 3 PM. Later flights inherit delays from earlier ones, so the first departures of the day usually run best.
Which airline is most on time from LAX to MSY?
Delta, with a season-adjusted 82% chance of operating and arriving on time over 968 flights. The adjustment compares each airline with what the route did in the months it flew, so a carrier that skipped a stormy month gets no free credit.

March (79% on time); the best was September (92%), averaged over Jun 2023 to May 2026.
Is this a prediction for my flight?
No. These are historical odds from the US DOT on-time reports, FAA advisories and airport weather records. Check your flight status and the FAA delay board on the day you fly.
