These figures cover 4,314 departures from Louis Armstrong New Orleans International in November 2025. On time means an arrival less than 15 minutes after the scheduled gate time, the DOT's threshold, and the national comparison uses every US departure in the same month rather than the whole year.
Against the year
November next to MSY's other months
Against MSY's own year, November ran 3 points better than the twelve-month rate of 78.5%, which makes it number four of twelve months, best first. Either side of it, October ran 78.9% on time and December 78.0%, so a trip moved by a few weeks would have landed in a worse stretch.

Departure window
The best time of day to leave MSY in November
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 21 points, against 6 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am957 flights90.8%
- 8am–11am617 flights89.5%
- 11am–2pm757 flights83.8%
- 2pm–5pm1,018 flights74.2%
- 5pm–8pm713 flights69.8%
- 8pm–5am252 flights75.2%
Scale runs 60% to 95%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 90.8% of the time, against 69.8% for the evening window. That is 21 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 2pm–5pm window is the busiest, with 1,018 flights scheduled in it.
Across the week, Wednesday is the strongest day at 90.1% on time and Sunday the weakest at 73.4%. 17 points is a smaller lever than departure hour, but it is free.

Delay causes
What held MSY up in November
One category carries most of the weight here. Late-arriving aircraft accounts for 44% of the 64,000 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.
- 44%Late-arriving aircraft
- 28%National Airspace System
- 25%Carrier
- 3%Extreme weather
- 0%Security
44% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 64,000 reported delay minutes here, that single category outweighs weather by 17 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 63,983 reported delay minutes.
Cancellations sit at 1.27% against a national 2.49%, which is ordinary. Diversions add another 0.16%.
7.1% of arrivals land an hour or more late, close to the national 7.8%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, which a normal layover absorbs.
