Share of 534 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 139 departures that left 15 minutes late or more, only 10 made it up before arrival. In the other direction, 37 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 FLL.
The worst days
Worst days for JetBlue on MSY to FLL
The latest arrival of the period was on 15 May 2026, 19 hours 48 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 15 May 2026 | 19 hours 48 minutes | Late-arriving aircraft |
| 22 May 2026 | 7 hours 47 minutes | Late-arriving aircraft |
| 16 March 2026 | 6 hours 57 minutes | National Airspace System |

Delay causes
Why JetBlue runs late on this route
Late-arriving aircraft accounts for 55% of the 14,000 delay minutes carriers reported here, and the remaining four split what is left.
- 55%Late-arriving aircraft
- 25%Carrier
- 17%National Airspace System
- 3%Extreme weather
- 1%Security
55% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 14,000 reported delay minutes here, that single category outweighs weather by 19 to one. The split is drawn from 13,610 reported delay minutes.
The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 84.3% on time here.
Cancellations sit at 2.19% against a national 1.89%, which is ordinary. Diversions add another 0.55%.
Connections and stage length
What a delay here costs
12.7% 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 54.0% on time across 550 flights, 15 points below 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. 549 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 MSY to FLL
Put together: treat all of this as provisional. 549 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 68.9% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 534 completed flights over 12 months sit behind that.
