MIA across all twelve months
These figures cover 10,460 departures from Miami 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 MIA's other months
Against MIA's own year, March ran 4 points worse than the twelve-month rate of 73.8%, which makes it number ten of twelve months, best first. Cancellations are where March stands out: 2.96% of scheduled departures were called off, 1.8 times the airport's rate across the year. Either side of it, February ran 75.3% on time and April 75.3%, so a trip moved by a few weeks would have landed in a better stretch.

Departure window
The best time of day to leave MIA in March
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 28 points, against 30 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am1,376 flights88.2%
- 8am–11am1,428 flights83.1%
- 11am–2pm1,140 flights67.2%
- 2pm–5pm1,917 flights68.5%
- 5pm–8pm2,087 flights60.0%
- 8pm–5am2,512 flights61.3%
Scale runs 50% to 95%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 60.0% on time, against 88.2% 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 8pm–5am window is the busiest, with 2,512 flights scheduled in it.
Across the week, Wednesday is the strongest day at 80.1% on time and Sunday the weakest at 57.7%. 22 points is a smaller lever than departure hour, but it is free.
Carrier by carrier
Which airlines ran best at MIA in March
The choice of carrier is not cosmetic here. Envoy Air arrives on time 79.0% of the time; Spirit Airlines manages 48.7%. Sample sizes sit next to every figure, because a two-point gap across 427 flights means less than a ten-point one.

Spirit Airlines cancels 11.2% 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 MIA up in March
One category carries most of the weight here. Late-arriving aircraft accounts for 42% of the 239,000 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.
- 42%Late-arriving aircraft
- 31%Carrier
- 23%National Airspace System
- 4%Extreme weather
- 0%Security
42% 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 239,000 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 239,482 reported delay minutes.
Cancellations run at 2.96%, against 2.90% nationally. That is roughly one flight in 30 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. 12.3% 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 MIA in March
For a March trip through MIA: plan on this being one of the airport's harder months. The 5am–8am departures held up best at 88.2% on time, and with 12.3% of arrivals an hour or more late, a connection here deserves more slack than the same trip in September would.
