Why flights are cancelled at LGA
Every cancellation carries a reason code filed by the airline that operated the flight. Departures, July 2023 – July 2026.
Extreme weather accounts for 48.9% of cancelled departures from LGA — about 1 in every 62 scheduled departures. That is 11 points lower than the 59.5% recorded across every airport FlyerIntel covers.
Share of cancellations
Of 15,086 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.
7,373 cancellations, 48.9% of the total.
Airport capacity, air traffic control flow programs, heavy traffic and ordinary bad weather. A system decision, not the airline’s.
4,725 cancellations, 31.3% of the total.
Crew, maintenance, aircraft cleaning, baggage or fueling: what BTS counts as within the carrier’s own control.
2,987 cancellations, 19.8% of the total.
A terminal evacuation, a security breach, screening equipment failure, or screening queues over 29 minutes.
1 cancellation, <0.1% of the total.
15,086 of 456,467 scheduled departures from LGA were cancelled. Ordinary bad weather is filed under air traffic, so weather’s full share is larger than its bar.

Shares are of each carrier’s own coded cancellations at LGA 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 LGA
Where US DOT attributed the delay minutes on departures from LGA.
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 LGA. Only delays of 15 minutes or more are attributed.
Of the 77,086 departures from LGA that left 15 or more minutes late and have a known inbound aircraft, 65% followed a flight that landed 15 or more minutes late. The other 35% 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%; LGA’s is the 13th highest.
The late flight is the one the same aircraft flew into LGA 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 LGA 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 LGA
Departures from LGA by the weather at the airport in the hour they were scheduled to leave, July 2023 – July 2026.
12.4% of scheduled departures from LGA left in an hour of bad weather. 9.0% of them were cancelled, against 2.2% in normal conditions, and 63.6% of the ones that flew arrived on time, against 80.9%. Those hours held 34% of all cancelled departures. That is about 3,823 more cancellations than the normal-conditions rate would give.
Cancellations were highest in thunderstorm hours: 35.8% of 3,371 departures, 16.3 times the normal rate.
Airlines filed 49% of LGA’s coded cancellations under extreme weather. By the weather at the airport in the scheduled hour, 34% 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 LGA 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 LGA
Cancellations by airline in hours of bad weather at LGA, against the other carriers in the same months, July 2023 – July 2026.
12% of the weather-matched departures from LGA left in an hour of bad weather at the airport. 9.0% of them were cancelled. That is 4.1 times the 2.2% in normal hours. No one carrier holds most of them; 10 airlines have enough to compare.
Compared with the other carriers at LGA in the same months, United Airlines (5.2% cancelled against 9.5% for the others; below them in normal hours too) cancelled the fewest in bad weather and Republic Airways (12.4% cancelled against 8.3% for the others; above them in normal hours too) the most. 7 more airlines are also clearly apart from the others.

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 10 listed airlines flew nearly every bad-weather departure at LGA. 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. SkyWest Airlines, Endeavor Air and Republic Airways 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 LGA
Time on the ground between one flight and the next of the same aircraft at LGA, and what a late arrival does to the next departure, July 2023 – July 2026.
The median turn at LGA is scheduled for 55 minutes on the ground and takes 62 minutes, against 56 minutes and 63 minutes across all airports. 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 (62,986 turns here, 64 minutes late on average), 71% of the turns were finished in no more than the scheduled ground time, against 68% across all airports. 76% 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 67% finished in the schedule and 74% leaving late. LGA finishes more late turns in the schedule than the network would, but lateness is passed on about as often. 41% of its late-inbound turns had a scheduled turn of 45 to 59 minutes, against 31% across all airports.
Turns at LGA against all airports

| Median actual turn | 62 min | 63 min | — |
| Turns that began with an aircraft 15+ minutes late | 19% | 19% | — |
| Late turns finished within the schedule | 71% | 68% | 67% |
| Late inbound that left 15+ minutes late | 76% | 72% | 74% |
| On-time inbound that left 15+ minutes late | 9% | 11% | — |
The last column is the network’s rate at the turn lengths scheduled at LGA, 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 LGA with its next departure from it by tail number; the aircraft is never named. These 334,250 turns are 73% of the flights that left LGA 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.

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