Departure window
When JetBlue runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 24 points, against 3 points between the best and worst carrier.
- 5am–8am—
- 8am–11am13 flights—
- 11am–2pm117 flights62.3%
- 2pm–5pm116 flights38.4%
- 5pm–8pm—
- 8pm–5am304 flights55.0%
Scale runs 30% to 70%. Rows with fewer than 30 flights show a dash.
The best window here is not the first bank but the 11am–2pm slot at 62.3% on time, ahead of 2pm–5pm at 38.4%. Where the curve peaks mid-day rather than at dawn, the constraint is usually congestion at one end rather than the aircraft's own rotation. The 8pm–5am window is the busiest, with 304 flights scheduled in it.
Across the year
JetBlue on FLL to MSY through the year
July is the worst month at 30.5% on time, 41 points below November, the best at 71.7%. Summer afternoon convection and peak-season schedules land on the same weeks every year, so this is a pattern you can book around rather than a run of bad luck. May was the busiest month here, with 64 flights.
Across the week, Wednesday is the strongest day at 66.2% on time and Sunday the weakest at 41.2%, a spread of 25 points.

Share of 539 completed flights by arrival against schedule.
30 of 244 late departures made up the time and arrived on time, 12% of them. In the other direction, 34 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at MSY.

Delay causes
Why JetBlue runs late on this route
Late-arriving aircraft accounts for 51% of the 17,000 delay minutes carriers reported here, and the remaining four split what is left.
- 51%Late-arriving aircraft
- 33%Carrier
- 14%National Airspace System
- 2%Extreme weather
51% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 17,000 reported delay minutes here, that single category outweighs weather by 21 to one. The split is drawn from 17,278 reported delay minutes.
Cancellations sit at 1.82% against a national 1.89%, which is ordinary. Diversions add another 0.18%.
Connections and stage length
What a delay here costs
19.9% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
The 673 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
The return leg is a different operation and performs like one: it runs 68.9% on time across 549 flights, 15 points above this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 15 points of difference.
One caution: this is a thin sample. 550 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.
What to do with this
Booking JetBlue on FLL to MSY
Put together: treat all of this as provisional. 550 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 54.0% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 539 completed flights over 12 months sit behind that.
