JetBlue Airways at Fort Lauderdale draws a C. About one flight in three arrives at least 15 minutes late, and the typical late arrival is about an hour behind schedule. Build slack into anything you connect to. That rests on 25,162 flights, of which United Airlines flew 9,046 at 82.6% on time.
Measured against the airport rather than the country, JetBlue Airways runs 3 points behind the 70.3% 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.

Against the competition
Every carrier at FLL, ranked
The choice of carrier is not cosmetic here. United Airlines arrives on time 82.6% of the time; Allegiant Air manages 60.9%. Sample sizes sit next to every figure, because a two-point gap across 4,734 flights means less than a ten-point one.

Spirit Airlines cancels 4.5% 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 33 points, against 22 points between the best and worst carrier.
- 5am–8am3,464 flights89.9%
- 8am–11am3,717 flights79.1%
- 11am–2pm3,894 flights63.0%
- 2pm–5pm2,910 flights61.2%
- 5pm–8pm4,697 flights60.5%
- 8pm–5am6,480 flights56.8%
Scale runs 50% to 95%.
The 8pm–5am window is where this operation falls apart: 56.8% on time, against 89.9% 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. The 8pm–5am window is the busiest, with 6,480 flights scheduled in it.
Across the year
Seasonal pattern
July is the worst month at 57.4% on time, 25 points below September, the best at 82.0%. 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. August was the busiest month here, with 3,058 flights.
Delay causes
What holds this operation up
- 43%Late-arriving aircraft
- 31%Carrier
- 23%National Airspace System
- 2%Extreme weather
- 0%Security
43% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 546,000 reported delay minutes here, that single category outweighs weather by 17 to one. The split is drawn from 546,378 reported delay minutes.
Cancellations run at 2.81%, against 1.89% nationally. That is roughly one flight in 40 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
13.1% 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.
25,162 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 delay figures matter less here than the 2.81% cancellation rate. A late arrival costs you about an hour; a cancelled flight costs you the day. Book the 5am–8am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 24,360 completed flights over 12 months sit behind that.
Common questions
JetBlue Airways at FLL
How often is JetBlue Airways at FLL delayed?
About one flight in three arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 33.1% of the 25,162 flights in this analysis, against 22.7% 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 82.6% on time across 9,046 flights. Allegiant Air is at the other end on 60.9%, a gap of 22 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 89.9% on time. The 8pm–5am window is the weakest at 56.8%, 33 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 July delays on JetBlue Airways at FLL?
July is the weakest month at 57.4% on time, compared with 82.0% in September. Across the year that is 25 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
