Departure window
The best time of day to leave FLL in July
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 37 points, against 12 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am1,528 flights91.7%
- 8am–11am837 flights91.0%
- 11am–2pm1,224 flights68.7%
- 2pm–5pm945 flights59.0%
- 5pm–8pm1,262 flights54.4%
- 8pm–5am1,148 flights61.3%
Scale runs 45% to 95%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 54.4% on time, against 91.7% 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 5am–8am window is the busiest, with 1,528 flights scheduled in it.
Across the week, Saturday is the strongest day at 79.6% on time and Sunday the weakest at 64.6%. 15 points is a smaller lever than departure hour, but it is free.
Carrier by carrier
Which airlines ran best at FLL in July
The choice of carrier is not cosmetic here. Spirit Airlines arrives on time 77.6% of the time; JetBlue Airways manages 66.0%. Sample sizes sit next to every figure, because a two-point gap across 1,546 flights means less than a ten-point one.

JetBlue Airways cancels 4.0% 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 July
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 169,000 reported delay minutes.
- 38%Late-arriving aircraft
- 31%National Airspace System
- 25%Carrier
- 6%Extreme weather
- 0%Security
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 169,000 reported delay minutes here, that single category outweighs weather by 7 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 168,989 reported delay minutes.
Cancellations sit at 2.23% against a national 2.45%, which is ordinary. Diversions add another 0.50%.
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 13.7% of arrivals land a full hour or more behind schedule, against 12.1% 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.
