FLL across all twelve months

These figures cover 6,437 departures from Fort Lauderdale-Hollywood International in May 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.

Against the year

May next to FLL's other months

Against FLL's own year, May ran 3 points better than the twelve-month rate of 71.5%, which makes it number four of twelve months, best first. Cancellations were unusually low for FLL in May, at 0.53% against 2.22% across the year. Either side of it, April ran 69.0% on time and June 74.3%, so a trip moved by a few weeks would have landed in a worse stretch.

Departure window

The best time of day to leave FLL in May

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 30 points, against 32 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

5am–8am1,087 flights93.1%
8am–11am924 flights85.2%
11am–2pm1,303 flights74.9%
2pm–5pm1,051 flights63.2%
5pm–8pm1,226 flights63.3%
8pm–5am846 flights71.4%

Scale runs 55% to 100%. Rows with fewer than 30 flights show a dash.

Book the early departure. Flights leaving between 5am–8am arrive on time 93.1% of the time, against 63.2% for the afternoon window. That is 30 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 1,303 flights scheduled in it.

Across the week, Tuesday is the strongest day at 81.1% on time and Friday the weakest at 70.3%. 11 points is a smaller lever than departure hour, but it is free.

Carrier by carrier

Which airlines ran best at FLL in May

The choice of carrier is not cosmetic here. United Airlines arrives on time 87.9% of the time; Allegiant Air manages 56.0%. Sample sizes sit next to every figure, because a two-point gap across 417 flights means less than a ten-point one.

The spread between United and Allegiant is 32 points, wide enough that it should decide the booking. On a hundred trips that is 32 more arrivals inside the on-time window.

Delay causes

What held FLL up in May

One category carries most of the weight here. Late-arriving aircraft accounts for 44% of the 98,000 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

44% 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 98,000 reported delay minutes here, that single category outweighs weather by 10 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 97,897 reported delay minutes.

Cancellations are rare at 0.53%, below the national 0.92% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.

7.5% of arrivals land an hour or more late, close to the national 7.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.
