Why flights are cancelled at PIT
Every cancellation carries a reason code filed by the airline that operated the flight. Departures, July 2023 – July 2026.
Extreme weather accounts for 54.2% of cancelled departures from PIT — about 1 in every 113 scheduled departures. That is 5 points lower than the 59.5% recorded across every airport FlyerIntel covers.

2,172 of 132,911 scheduled departures from PIT 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 PIT
Where US DOT attributed the delay minutes on departures from PIT.

Share of the delay minutes US DOT attributed to each cause for departures from PIT. Only delays of 15 minutes or more are attributed.
Of the 20,079 departures from PIT 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%; PIT’s is the 22nd highest.
The late flight is the one the same aircraft flew into PIT 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 PIT 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 PIT
Departures from PIT by the weather at the airport in the hour they were scheduled to leave, July 2023 – July 2026.
14.4% of scheduled departures from PIT left in an hour of bad weather. 3.2% of them were cancelled, against 1.3% in normal conditions, and 72.3% of the ones that flew arrived on time, against 83.7%. Those hours held 28% of all cancelled departures. That is about 362 more cancellations than the normal-conditions rate would give.
Cancellations were highest in fog hours: 8.5% of 1,015 departures, 6.4 times the normal rate.
Airlines filed 54% of PIT’s coded cancellations under extreme weather. By the weather at the airport in the scheduled hour, 28% 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 PIT 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 100.0% 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 PIT
Cancellations by airline in hours of bad weather at PIT, against the other carriers in the same months, July 2023 – July 2026.
14% of the weather-matched departures from PIT left in an hour of bad weather at the airport. 3.2% of them were cancelled. That is 2.4 times the 1.3% in normal hours. No one carrier holds most of them; 8 airlines have enough to compare.
Compared with the other carriers at PIT in the same months, United Airlines (1.2% cancelled against 3.6% for the others; below them in normal hours too) cancelled the fewest in bad weather and JetBlue (6.5% cancelled against 3.1% for the others; above them in normal hours too) the most. 3 more airlines are also clearly apart from the others.
Airlines in bad weather at PIT
Scheduled departures, July 2023 – July 2026| Airline | Bad-weather departures | Cancelled | Other carriers | Normal hours |

| United Airlines | 1,5498% of bad-weather | 1.2%below the others | 3.6% | 0.9%others 1.3% |

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 8 listed airlines flew 91% of the bad-weather departures at PIT; 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 flies for Delta Air Lines, United Airlines and 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 PIT
Time on the ground between one flight and the next of the same aircraft at PIT, and what a late arrival does to the next departure, July 2023 – July 2026.
The median turn at PIT is scheduled for 50 minutes on the ground and takes 55 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 typical turn runs 5 minutes over its schedule, closer to it than the 7 minutes across all airports.
When the aircraft landed 15 or more minutes late (15,543 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, 9% did (all airports 11%).
Given the turn lengths scheduled here, the network’s rates would give 62% finished in the schedule and 78% leaving late. PIT finishes more late turns in the schedule than the network would, but lateness is passed on about as often. 38% of its late-inbound turns had a scheduled turn of 45 to 59 minutes, against 31% across all airports.
Turns at PIT against all airports

| Median scheduled turn | 50 min | 56 min | — |
| Median actual turn | 55 min | 63 min | — |
| Turns that began with an aircraft 15+ minutes late | 18% | 19% | — |
| Late turns finished within the schedule | 66% | 68% | 62% |
| Late inbound that left 15+ minutes late | 78% | 72% | 78% |
| On-time inbound that left 15+ minutes late | 9% | 11% | — |
The last column is the network’s rate at the turn lengths scheduled at PIT, 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 PIT with its next departure from it by tail number; the aircraft is never named. These 84,578 turns are 64% of the flights that left PIT 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 PIT and does not rate the airport.

"Elsewhere" is every other covered airport together, taken from the same aggregates as this page with PIT’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 PIT
On-time arrival rate by scheduled local departure time: each weekday and hour, and averaged over the week.
Flights departing 5–9 AM arrived on time 90.3% of the time, against 66.0% for 9 PM–5 AM departures — a gap of 24.3 percentage points.

Wednesday 5–6 AM was the most reliable slot at PIT (95.1% on time, 643 flights) and Sunday 8–9 PM the least (62.2%, 555 flights).
Hour of departure matters more than day of the week: hourly averages sit a typical 8.5 points from the airport-wide rate, weekday averages 1.7 points.
