Why flights are cancelled at MIA
Every cancellation carries a reason code filed by the airline that operated the flight. Departures, July 2023 – July 2026.
Extreme weather accounts for 71.5% of cancelled departures from MIA — about 1 in every 94 scheduled departures. That is 12 points higher than the 59.5% recorded across every airport FlyerIntel covers.
Share of cancellations
Of 5,082 cancelled departures carrying a reason code.
What each reason means
Conditions the carrier judged severe enough to stop the flight: a blizzard, a hurricane, a line of thunderstorms.
3,635 cancellations, 71.5% of the total.
Crew, maintenance, aircraft cleaning, baggage or fueling: what BTS counts as within the carrier’s own control.
906 cancellations, 17.8% of the total.
Airport capacity, air traffic control flow programs, heavy traffic and ordinary bad weather. A system decision, not the airline’s.
541 cancellations, 10.6% of the total.
A terminal evacuation, a security breach, screening equipment failure, or screening queues over 29 minutes.
0 cancellations, 0.0% of the total.
5,082 of 340,469 scheduled departures from MIA were cancelled. Ordinary bad weather is filed under air traffic, so weather’s full share is larger than its bar.
By carrier

Shares are of each carrier’s own coded cancellations at MIA and run across the row, so they total 100%. “Rate” is cancellations as a share of that carrier’s scheduled departures here. Two carriers on the same runways in the same weather can file very different splits, so read this as what each airline reported about itself, not as a ranking of fault. Carriers below the published minimum of coded cancellations are not listed.

Why flights run late at MIA
Where US DOT attributed the delay minutes on departures from MIA.
the inbound aircraft was late, so this flight started late
crew, maintenance, boarding and fueling, all within the carrier’s control
airspace and airport capacity, including weather-driven flow control
weather severe enough to stop this flight specifically
screening or terminal security incidents
Share of the delay minutes US DOT attributed to each cause for departures from MIA. Only delays of 15 minutes or more are attributed.
Of the 66,347 departures from MIA that left 15 or more minutes late and have a known inbound aircraft, 50% followed a flight that landed 15 or more minutes late. The other 50% left late even though the aircraft had come in on time or early. Across the 64 covered airports that share runs from 47% to 73%, with a median of 62%; MIA’s is the 4th lowest.
The late flight is the one the same aircraft flew into MIA just before, found from the tail number in the DOT file. Airlines and hours differ from one airport to the next, so this describes the departures from MIA and does not rate the airport.
An airport is only partly the author of its own delays. Late-arriving aircraft describes the national schedule arriving here more than anything about this airfield. Air traffic control covers airspace and airport capacity, which is where a congested airport shows up; only the airline category sits squarely inside the carriers’ own operation. How differently they run it is further down this page.

What weather costs at MIA
Departures from MIA by the weather at the airport in the hour they were scheduled to leave, July 2023 – July 2026.
4.6% of scheduled departures from MIA left in an hour of bad weather. 4.5% of them were cancelled, against 1.3% in normal conditions, and 50.6% of the ones that flew arrived on time, against 74.1%. Those hours held 14% of all cancelled departures. That is about 493 more cancellations than the normal-conditions rate would give.
Cancellations were highest in fog hours: 10.6% of 549 departures, 7.9 times the normal rate.
Airlines filed 72% of MIA’s coded cancellations under extreme weather. By the weather at the airport in the scheduled hour, 14% of cancelled departures were in bad-weather hours. A code is the airline’s stated reason and an hour’s weather is what the airport reported, so the two need not match.

A departure is counted in every row its hour fits, so the rows overlap and do not add up. Left on time is a departure under 15 minutes late, and arrived on time an arrival under 15 minutes late; cancelled is the share of scheduled departures. Rows with fewer than 120 departures are not scored.
This is the weather reported at MIA in the hour a flight was scheduled to leave. It leaves out the weather at the destination and on the way, weather that arrived after the scheduled time, and anything else that goes wrong in a bad hour. An hour takes the worst conditions any report in it gave. Weather was matched to 99.9% of the airport’s scheduled departures; the rest left in hours with no report, or at a scheduled time the flight records cannot place exactly. Bad-weather hours are compared with normal hours at the same airport, not with what the same flights would have done in a clear sky: they also fall more often in some seasons and at some times of day.

Which airlines hold up in bad weather at MIA
Cancellations by airline in hours of bad weather at MIA, against the other carriers in the same months, July 2023 – July 2026.
5% of the weather-matched departures from MIA left in an hour of bad weather at the airport. 4.5% of them were cancelled. That is 3.3 times the 1.3% in normal hours. No one carrier holds most of them; 7 airlines have enough to compare.
Compared with the other carriers at MIA in the same months, Delta Air Lines (2.0% cancelled against 4.7% for the others; level with them in normal hours, so a bad-weather difference) cancelled the fewest in bad weather and Envoy Air (6.4% cancelled against 4.4% for the others) the most. 3 more airlines are also clearly apart from the others.
Airlines in bad weather at MIA
Scheduled departures, July 2023 – July 2026| Airline | Bad-weather departures | Cancelled | Other carriers | Normal hours |

| Delta Air Lines | 1,77411% of bad-weather | 2.0%below the others | 4.7% | 1.4%others 1.3% |

| Envoy Air | 1,84012% of bad-weather | 6.4%above the others | 4.4% | 0.8%others 1.4% |
Best first. The other carriers’ column applies their rate in each month to the airline’s own departures, so a stormy month is not held against it; the normal-hours column gives the same pair outside bad weather.
The 7 listed airlines flew 98% of the bad-weather departures at MIA; a carrier under 500 is not listed. The comparison does not hold the hour of the day, the destination or the aircraft fixed, and a gap counts as clear only at 2 standard errors and 0.3 points. Envoy Air flies for American Airlines and is counted as a carrier of its own here, though it shares the airport’s gates, its de-icing and often its decisions to cancel.

Turning aircraft around at MIA
Time on the ground between one flight and the next of the same aircraft at MIA, and what a late arrival does to the next departure, July 2023 – July 2026.
The median turn at MIA is scheduled for 66 minutes on the ground and takes 75 minutes, against 56 minutes and 63 minutes across all airports. Aircraft are given longer on the ground here than at the typical airport. The typical turn runs 9 minutes over its schedule, more than the 7 minutes it does across all airports. 21.8% of turns here began with an aircraft that landed 15 or more minutes late, above the 18.9% for all airports.
When the aircraft landed 15 or more minutes late (42,911 turns here, 59 minutes late on average), 67% of the turns were finished in no more than the scheduled ground time, against 68% across all airports. 69% of those flights left 15 or more minutes late, against 72%. After an aircraft that landed on time, 15% did (all airports 11%).
Given the turn lengths scheduled here, the network’s rates would give 75% finished in the schedule and 64% leaving late. MIA does worse on both counts: fewer late turns are finished in the schedule and more late aircraft become late departures, so a late arrival is more likely to stay late here than the schedule alone explains. 46% of its late-inbound turns had a scheduled turn of 60 to 89 minutes, against 29% across all airports.
Turns at MIA against all airports

The last column is the network’s rate at the turn lengths scheduled at MIA, band by band from under 30 minutes to 3 to 6 hours. A turn finishes within the schedule when the aircraft spent no more time on the ground than the schedule gave it.
A turn pairs an aircraft’s landing at MIA with its next departure from it by tail number; the aircraft is never named. These 197,040 turns are 58% of the flights that left MIA in the period; the rest are an aircraft’s first flight after a long stay, flights without a usable inbound, and cancelled flights. Ground time runs from the gate. Turns under 30 minutes are kept, but most leave late even after an on-time landing. Airlines set their own turn schedules, so this describes the airlines that fly at MIA and does not rate the airport.

"Elsewhere" is every other covered airport together, taken from the same aggregates as this page with MIA’s own flights removed (for airlines, that airline’s flights from all its other airports). Hours, months and airlines appear only where both sides have at least 120 completed flights (airlines 500) and the gap is at least 2 points and 2 standard errors; only the largest gap in each direction is shown. The taxi figure is weighted by departures and has no error estimate, so it appears from 2 minutes.

International arrivals
How long passport control normally takes here, hour by hour and hall by hall. This is the arrivals queue, not departure security — and it is history, not a live wait.
A US passport clears North Terminal, MIA’s busiest hall, in a typical 13 min; everyone else in the same terminal typically takes 21 min, and 43 min on a busy day. These are separate halls, separately staffed — CBP’s single combined figure of 17 min is a number few arrivals actually experience.
Terminal by terminal, across the day
| Terminal | US passports | US busy day | Other passports | Other busy day | Global Entry |
|---|---|---|---|---|---|
| North Terminal | 13 min | 21 min | 21 min | 43 min | 13.2% of arrivals |
| South Terminal | 8 min | 14 min | 15 min | 40 min | 6.6% of arrivals |
| Central Terminal | 5 min | 13 min | 18 min | 44 min | 8.9% of arrivals |
MIA’s halls are not interchangeable: passengers on other passports typically clear North Terminal in 21 min against 15 min at South Terminal. Which one you land in is decided by the airline you booked, not by you.
Your terminal is set by the airline you arrive on, not by you. This is here so you can read the hall you will actually land in.

US passports: clearing in the 5 PM–6 PM hour typically takes 17 min, against 8 min in the 10 PM–11 PM hour — 9 min between the slowest and fastest of 19 measured hours.
All other passports: clearing in the 11 AM–12 PM hour typically takes 31 min, against 9 min in the 10 PM–11 PM hour — 22 min between the slowest and fastest of 19 measured hours.
The hour is when CBP processed the passenger, not when the aircraft landed — allow for the walk from the gate. Hours with fewer than 120 days of records are not listed rather than shown as an estimate, which is why a terminal’s quietest hours are usually absent. “Busy day” is the 90th percentile: one arrival in ten is worse than that. Booths are how many CBP had open, and they follow the queue rather than prevent it — the busiest hours are staffed hardest and are still the slowest.
Source: US Customs and Border Protection · 2024-08-28 to 2026-10-16 · These are CBP passport control waits for arriving international passengers — a different queue from TSA departure screening. CBP publishes them about two days in arrears, so every figure here describes what has been typical over 2024-08-28 to 2026-10-16, and none of it is a live queue or a forecast for your flight. US and non-US passengers are reported separately by CBP and are kept separate here, because they are separate halls. FlyerIntel publishes a terminal or an hour only where CBP filed at least 120 hourly records for it, and an hour-by-hour breakdown only where at least 6 hours clear that floor.
