Why flights are cancelled at MKE
Every cancellation carries a reason code filed by the airline that operated the flight. Departures, July 2023 – July 2026.
Extreme weather accounts for 64.4% of cancelled departures from MKE — about 1 in every 93 scheduled departures. That is close to the split across every airport FlyerIntel covers.
Share of cancellations
Of 1,473 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.
949 cancellations, 64.4% of the total.
Crew, maintenance, aircraft cleaning, baggage or fueling: what BTS counts as within the carrier’s own control.
280 cancellations, 19.0% of the total.
Airport capacity, air traffic control flow programs, heavy traffic and ordinary bad weather. A system decision, not the airline’s.
244 cancellations, 16.6% 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.
1,473 of 87,869 scheduled departures from MKE were cancelled. Ordinary bad weather is filed under air traffic, so weather’s full share is larger than its bar.

Why flights run late at MKE
Where US DOT attributed the delay minutes on departures from MKE.
crew, maintenance, boarding and fueling, all within the carrier’s control
the inbound aircraft was late, so this flight started late
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 MKE. Only delays of 15 minutes or more are attributed.
Of the 14,537 departures from MKE that left 15 or more minutes late and have a known inbound aircraft, 64% followed a flight that landed 15 or more minutes late. The other 36% 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%; MKE’s is the 18th highest.
The late flight is the one the same aircraft flew into MKE 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 MKE 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 MKE
Departures from MKE by the weather at the airport in the hour they were scheduled to leave, July 2023 – July 2026.
12.7% of scheduled departures from MKE left in an hour of bad weather. 3.8% of them were cancelled, against 1.3% in normal conditions, and 70.7% of the ones that flew arrived on time, against 82.3%. Those hours held 29% of all cancelled departures. That is about 273 more cancellations than the normal-conditions rate would give.
Cancellations were highest in fog hours: 8.2% of 825 departures, 6.1 times the normal rate.
Airlines filed 64% of MKE’s coded cancellations under extreme weather. By the weather at the airport in the scheduled hour, 29% 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 MKE 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 MKE
Cancellations by airline in hours of bad weather at MKE, against the other carriers in the same months, July 2023 – July 2026.
13% of the weather-matched departures from MKE left in an hour of bad weather at the airport. 3.8% of them were cancelled. That is 2.8 times the 1.3% in normal hours. No one carrier holds most of them; 5 airlines have enough to compare.
Compared with the other carriers at MKE in the same months, Southwest Airlines (2.4% cancelled against 5.1% for the others; below them in normal hours too) cancelled the fewest in bad weather and SkyWest Airlines (6.4% cancelled against 3.6% for the others; level with them in normal hours, so a bad-weather difference) the most. 2 more airlines are also clearly apart from the others.
Airlines in bad weather at MKE
Scheduled departures, July 2023 – July 2026| Airline | Bad-weather departures | Cancelled | Other carriers | Normal hours |
|---|---|---|---|---|
| Southwest Airlines | 3,93235% of bad-weather | 2.4%below the others | 5.1% | 0.6%others 1.7% |
| Delta Air Lines | 1,47913% of bad-weather | 2.5%below the others | 3.9% | 1.0%others 1.4% |

| SkyWest Airlines | 2,31121% of bad-weather | 6.4%above the others | 3.6% | 1.4%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 5 listed airlines flew 85% of the bad-weather departures at MKE; 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. Republic Airways and SkyWest Airlines fly for mainline airlines and are counted as carriers of their own here, though they share the airport’s gates, its de-icing and often its decisions to cancel.

Turning aircraft around at MKE
Time on the ground between one flight and the next of the same aircraft at MKE, and what a late arrival does to the next departure, July 2023 – July 2026.
The median turn at MKE is scheduled for 45 minutes on the ground and takes 52 minutes, against 56 minutes and 63 minutes across all airports. Aircraft are given less time on the ground here than at the typical airport. The 7 minutes by which the typical turn runs over its schedule are about what it is across all airports.
When the aircraft landed 15 or more minutes late (10,878 turns here, 58 minutes late on average), 66% of the turns were finished in no more than the scheduled ground time, against 68% across all airports. 78% of those flights left 15 or more minutes late, against 72%. After an aircraft that landed on time, 8% did (all airports 11%).
Given the turn lengths scheduled here, the network’s rates would give 59% finished in the schedule and 80% leaving late. MKE does better on both counts: more late turns are finished in the schedule and fewer late aircraft become late departures, so the turn recovers lateness here beyond what the schedule explains. 40% of its late-inbound turns had a scheduled turn of 30 to 44 minutes, against 20% across all airports.
Turns at MKE against all airports
57,091 turns, July 2023 – July 2026| Measure | MKE | All airports | All airports, same turn lengths |

| Median actual turn | 52 min | 63 min | — |
| Turns that began with an aircraft 15+ minutes late | 19% | 19% | — |
| Late turns finished within the schedule | 66% | 68% | 59% |
| Late inbound that left 15+ minutes late | 78% | 72% | 80% |
| On-time inbound that left 15+ minutes late | 8% | 11% | — |
The last column is the network’s rate at the turn lengths scheduled at MKE, 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 MKE with its next departure from it by tail number; the aircraft is never named. These 57,091 turns are 65% of the flights that left MKE 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 MKE and does not rate the airport.

"Elsewhere" is every other covered airport together, taken from the same aggregates as this page with MKE’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.
Best time to fly from MKE
On-time arrival rate by scheduled local departure time: each weekday and hour, and averaged over the week.
