Historical statistics for March 2026, not live status or a forecast for this year’s March. For today’s conditions at FLL, see live FAA status.
FLL in March carries a cancellation problem, not just a delay problem: 4.7% of scheduled flights never operate, against 2.9% nationally. Of the ones that do fly, a little over half of flights arrive on time, worth a D− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 9,928 flights, of which United Airlines flew 978 at 78.7% on time.
United Airlines is the most reliable of the eight carriers covered here at 78.7% on time across 978 flights.

FLL across all twelve months
These figures cover 9,928 departures from Fort Lauderdale-Hollywood International in March 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
March next to FLL's other months
Against FLL's own year, March ran 12 points worse than the twelve-month rate of 71.5%, which makes it the worst of the twelve months in the data. Cancellations are where March stands out: 4.66% of scheduled departures were called off, 2.1 times the airport's rate across the year. Either side of it, February ran 67.3% on time and April 69.0%, so a trip moved by a few weeks would have landed in a better stretch.

Departure window
The best time of day to leave FLL in March
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 42 points, against 37 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am1,772 flights83.6%
- 8am–11am1,458 flights77.2%
- 11am–2pm1,559 flights56.5%
- 2pm–5pm1,490 flights51.7%
- 5pm–8pm1,870 flights48.5%
- 8pm–5am1,779 flights41.8%
Scale runs 35% to 90%. Rows with fewer than 30 flights show a dash.
The 8pm–5am window is where this operation falls apart: 41.8% on time, against 83.6% 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 1,870 flights scheduled in it.
Across the week, Wednesday is the strongest day at 69.4% on time and Sunday the weakest at 48.1%. 21 points is a smaller lever than departure hour, but it is free.
Carrier by carrier
Which airlines ran best at FLL in March
The choice of carrier is not cosmetic here. United Airlines arrives on time 78.7% of the time; Spirit Airlines manages 41.9%. Sample sizes sit next to every figure, because a two-point gap across 2,190 flights means less than a ten-point one.

| JetBlue Airways | 2,424 | 59.9% | 68 min | 2.43% | D |

Spirit Airlines cancels 10.4% 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 March
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 315,000 reported delay minutes.
- 37%Late-arriving aircraft
- 31%Carrier
- 26%National Airspace System
- 5%Extreme weather
- 0%Security
37% 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 315,000 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 314,753 reported delay minutes.
Cancellations run at 4.66%, against 2.90% nationally. That is about one flight in twenty 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.
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 17.8% of arrivals land a full hour or more behind schedule, against 9.5% 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.
What to do with this
Flying from FLL in March
For a March trip through FLL: plan on this being one of the airport's harder months. The 5am–8am departures held up best at 83.6% on time, and with 17.8% of arrivals an hour or more late, a connection here deserves more slack than the same trip in September would.
