These figures cover 8,610 departures from Fort Lauderdale-Hollywood International in April 2026. On time means an arrival less than 15 minutes after the scheduled gate time, the DOT's threshold, and the national comparison uses every US departure in the same month rather than the whole year.

Departure window

The best time of day to leave FLL in April

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 31 points, against 31 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

5am–8am1,478 flights87.4%
8am–11am1,223 flights83.4%
11am–2pm1,448 flights69.0%
2pm–5pm1,279 flights63.9%
5pm–8pm1,691 flights56.9%
8pm–5am1,491 flights57.0%

Scale runs 50% to 95%. Rows with fewer than 30 flights show a dash.

The 5pm–8pm window is where this operation falls apart: 56.9% on time, against 87.4% 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 5pm–8pm window is the busiest, with 1,691 flights scheduled in it.

Across the week, Saturday is the strongest day at 78.0% on time and Sunday the weakest at 55.4%. 23 points is a smaller lever than departure hour, but it is free.

Carrier by carrier

Which airlines ran best at FLL in April

The choice of carrier is not cosmetic here. United Airlines arrives on time 86.0% of the time; Allegiant Air manages 55.4%. Sample sizes sit next to every figure, because a two-point gap across 475 flights means less than a ten-point one.

Spirit Airlines cancels 3.7% 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.

Delay causes

What held FLL up in April

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 171,000 reported delay minutes.

Late-arriving aircraft
38%
Carrier
33%
National Airspace System
26%
Extreme weather
2%
Security
0%

38% 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 171,000 reported delay minutes here, that single category outweighs weather by 17 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 171,058 reported delay minutes.

Cancellations sit at 1.06% against a national 0.90%, which is ordinary. Diversions add another 0.42%.

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 10.8% of arrivals land a full hour or more behind schedule, against 6.4% 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.
