United Airlines at Fort Lauderdale lands a B, 5 points better than the national rate of 77.3%. About one flight in six arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That rests on 9,046 flights, of which United Airlines flew 9,046 at 82.6% on time.
Measured against the airport rather than the country, United Airlines runs 12 points ahead of 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.

#1
Of 9 carriers clearing the floor at FLL
These figures cover 9,046 flights between September 2025 and August 2026. The median arrival is 10 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.
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 United Airlines flies from FLL
United Airlines operates 7 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 22 points, against 22 points between the best and worst carrier.
- 5am–8am1,173 flights93.0%
- 8am–11am2,101 flights91.0%

Scale runs 60% to 100%.
Book the early departure. Flights leaving between 5am–8am arrive on time 93.0% of the time, against 70.8% for the afternoon window. That is 22 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 11am–2pm window is the busiest, with 2,387 flights scheduled in it.
Across the year
Seasonal pattern
July is the worst month at 78.5% on time, 9 points below May, the best at 87.9%. 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. March was the busiest month here, with 978 flights.
Delay causes

- 31%Late-arriving aircraft
- 21%Carrier
- 5%Extreme weather
43% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 54,000 minutes out of 126,000, against a national NAS share of 21%. The split is drawn from 125,941 reported delay minutes.
Cancellations sit at 1.15% against a national 1.89%, which is ordinary. Diversions add another 0.38%.
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 a little over an hour, which a normal layover absorbs.
The sample behind these figures is 9,046 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.
Put together: take the 5am–8am departure, avoid July if the dates are flexible, and if two carriers are within a few dollars of each other, United is the one with the record behind it. None of that guarantees an on-time arrival; it moves the odds by 22 points, which is the most any booking decision can do. 8,908 completed flights over 12 months sit behind that.
Common questions
United Airlines at FLL
How often is United Airlines at FLL delayed?
About one flight in six arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 17.4% of the 9,046 flights in this analysis, against 22.7% nationally. Delayed flights are late by a little over an hour on average.
Which airline is most reliable on United Airlines 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 United Airlines at FLL?
The 5am–8am departure window is the strongest at 93.0% on time. The 2pm–5pm window is the weakest at 70.8%, 22 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 United Airlines at FLL?
July is the weakest month at 78.5% on time, compared with 87.9% in May. Across the year that is 9 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
