JetBlue on LAS to FLL lands a B, level with the national rate of 77.3%. Roughly one flight in five arrives 15 minutes late or worse, and those flights are late by about an hour on average. That rests on 833 flights, with a median arrival 6 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate JetBlue on LAS to FLL from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

These figures cover 833 flights between September 2025 and August 2026. The median arrival is 6 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

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 16 points, against half a point between the best and worst carrier.
- 5am–8am184 flights88.6%
- 8am–11am87 flights79.8%
- 11am–2pm238 flights75.9%
- 2pm–5pm—
- 5pm–8pm—
- 8pm–5am324 flights72.6%
Scale runs 65% to 95%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 88.6% of the time, against 72.6% for the overnight window. That is 16 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8pm–5am window is the busiest, with 324 flights scheduled in it.

Share of 809 completed flights by arrival against schedule.
36 of 173 late departures made up the time and arrived on time, 21% of them. In the other direction, 43 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 LAS to FLL
The latest arrival of the period was on 19 November 2025, 6 hours 49 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 19 November 2025 | 6 hours 49 minutes | Late-arriving aircraft |
| 20 July 2026 | 5 hours 3 minutes | Late-arriving aircraft |
| 12 March 2026 | 4 hours 23 minutes | Late-arriving aircraft |

Delay causes
Why JetBlue runs late on this route
Late-arriving aircraft accounts for 46% of the 10,000 delay minutes carriers reported here, and the remaining four split what is left.
- 46%Late-arriving aircraft
- 32%Carrier
- 20%National Airspace System
- 1%Extreme weather
46% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 10,000 reported delay minutes here, that single category outweighs weather by 32 to one. The split is drawn from 10,446 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 88.6% on time here.
Cancellations sit at 2.16% against a national 1.89%, which is ordinary. Diversions add another 0.72%.
Connections and stage length
What a delay here costs
6.8% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.
At 2,173 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.
The return leg runs 77.9% on time across 834 flights, within half a point of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
One caution: this is a thin sample. 833 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 LAS to FLL
Put together: treat all of this as provisional. 833 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 77.8% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 809 completed flights over 12 months sit behind that.
