Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with JetBlue Airways.
JetBlue on LAX to FLL sits in the middle of the pack with a B+. Close to three flights in four arrive on time by the DOT's definition, 2 points worse than the national rate of 77.6%. The late ones land about an hour behind schedule. That rests on 1,748 flights, with a median arrival 3 minutes early.
The US average over the same twelve months is 77.6%, so there is little to separate JetBlue on LAX 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 1,748 flights between July 2025 and June 2026. Beyond the headline rate, 8.1% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Carrier by carrier
JetBlue against every carrier on LAX to FLL
JetBlue flew 1,748 of the 2,275 flights on LAX to FLL, most of the route. Its 75.8% on time is 2 points better than the route as a whole, which runs 74.0%. Ranked by on-time rate it is first of three carriers on the route, where the range runs from JetBlue at 75.8% to Spirit at 56.4%. Two of those carriers flew fewer than 365 flights here, so treat their positions as rough.
Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

Departure window
When JetBlue runs best on this route
Departure time is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 1,748 flights.
- 5am–8am89 flights76.7%
- 8am–11am464 flights77.9%
- 11am–2pm461 flights71.6%
- 2pm–5pm300 flights75.0%
- 5pm–8pm—
- 8pm–5am434 flights78.2%
Scale runs 65% to 85%. Rows with fewer than 30 flights show a dash.
The weak window here is the middle of the day, not the evening: 11am–2pm runs 71.6% on time against 78.2% for 8pm–5am. That shape usually means a departure bank rather than an accumulating delay, so the recovery later in the afternoon is real rather than noise. The 8am–11am window is the busiest, with 464 flights scheduled in it.
Across the year
JetBlue on LAX to FLL through the year
September is the best month on the calendar at 95.8% on time. Shoulder season thins the schedule and takes the summer weather with it, and the operation gets its margin back. December was the busiest month here, with 187 flights.
Across the week, Tuesday is the strongest day at 80.2% on time and Thursday the weakest at 70.5%. 10 points is a smaller lever than departure hour, but it is free.
Delay causes
Why JetBlue runs late on this route
One category carries most of the weight here. Late-arriving aircraft accounts for 45% of the 25,000 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.
- 45%Late-arriving aircraft
- 32%Carrier
- 24%National Airspace System
45% 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 25,000 reported delay minutes here, that single category outweighs weather by 45 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 25,139 reported delay minutes.
Cancellations sit at 0.97% against a national 1.81%, which is ordinary. Diversions add another 0.40%.
Connections and stage length
What a delay here costs
8.1% of arrivals land an hour or more late, close to the national 8.1%. 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 about an hour, which a normal layover absorbs.
At 2,343 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 76.0% on time across 1,749 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.
The sample behind these figures is 1,748 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.
What to do with this
Booking JetBlue on LAX to FLL
Put together: the calendar is the biggest lever here, not the carrier or the hour. September runs 95.8% on time and March 48.2%, a swing of 48 points. If the dates move at all, move them out of March before you think about anything else. 1,724 completed flights over 12 months sit behind that.
