JetBlue Airways at Fort Lauderdale sits in the middle of the pack with a C. About seven flights in ten arrive on time by the DOT's definition, 9 points worse than the national rate of 77.4%. The late ones land about an hour behind schedule. That rests on 21,594 flights, of which United Airlines flew 8,844 at 82.1% on time.
Measured against the airport rather than the country, JetBlue Airways runs 3 points behind the 71.4% weighted average across all carriers at FLL. That is the comparison worth making: every operator here works the same runways, the same airspace and the same weather.

#7
Of 9 carriers clearing the floor at FLL
These figures cover 22,000 flights between June 2025 and May 2026. Beyond the headline rate, 12.4% 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.
Against the competition
Every carrier at FLL, ranked
The choice of carrier is not cosmetic here. United Airlines arrives on time 82.1% of the time; Allegiant Air manages 62.5%. Sample sizes sit next to every figure, because a two-point gap across 4,573 flights means less than a ten-point one.

Spirit Airlines cancels 3.5% of what it schedules here, the highest in the table. A cancelled flight never appears in an on-time rate, so read that column alongside the punctuality one rather than after it.
Route by route
Where JetBlue Airways flies from FLL
JetBlue Airways operates 25 routes out of FLL with enough volume to report. Route records inside one carrier at one airport still spread widely, because a short shuttle and a transcontinental have very different exposure to a late inbound.

Departure window
Best time of day for this operation
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 32 points, against 20 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am3,372 flights90.3%
- 8am–11am3,203 flights80.1%
- 11am–2pm2,935 flights61.8%
- 2pm–5pm2,568 flights62.8%
- 5pm–8pm4,085 flights61.2%
- 8pm–5am5,431 flights58.6%
Scale runs 50% to 95%. Rows with fewer than 30 flights show a dash.
The 8pm–5am window is where this operation falls apart: 58.6% on time, against 90.3% for the 5am–8am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in.
Across the year
Seasonal pattern
December is the weak month at 59.0% on time, against 82.0% in September. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days.
Delay causes
What holds this operation up
- 41%Late-arriving aircraft
- 30%Carrier
- 26%National Airspace System
- 3%Extreme weather
- 0%Security
41% 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 447,000 reported delay minutes here, that single category outweighs weather by 16 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.
Cancellations sit at 2.15% against a national 1.80%, which is ordinary. Diversions add another 0.35%.
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 12.4% of arrivals land a full hour or more behind schedule, against 8.2% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.
21,594 flights sit behind these numbers, which is a large enough sample that the headline rate is not moving on noise. Where a sub-group falls below 30 flights the site shows a dash instead of a percentage.
Put together: the calendar is the biggest lever here, not the carrier or the hour. September runs 82.0% on time and December 59.0%, a swing of 23 points. If the dates move at all, move them out of December before you think about anything else.
Common questions
JetBlue Airways at FLL
How often is JetBlue Airways at FLL delayed?
About one flight in three arrive at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 31.8% of the 21,594 flights in this analysis, against 22.6% nationally. Delayed flights are late by about an hour on average.
Which airline is most reliable on JetBlue Airways at FLL?
United Airlines leads at 82.1% on time across 8,844 flights. Allegiant Air is at the other end on 62.5%, a gap of 20 points. Sample size matters as much as the percentage: a rate built from a few hundred flights moves around far more than one built from ten thousand.
What time of day has the fewest delays on JetBlue Airways at FLL?
The 5am–8am departure window is the strongest at 90.3% on time. The 8pm–5am window is the weakest at 58.6%, 32 points behind. Later departures inherit delays from earlier flights the same aircraft has already flown, which is why the curve slopes the way it does.
How bad are December delays on JetBlue Airways at FLL?
December is the weakest month at 59.0% on time, compared with 82.0% in September. Across the year that is 23 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
