Calculated from 304,230 flights. How this is calculated
Against the 15 carriers FlyerIntel covers — all measured over the same period, from the same source — Endeavor Air ranks 1st of 15 for on-time arrivals, 13th for cancellations and 4th for arrivals more than an hour late. The full table is at the foot of this page.

Why Endeavor Air cancels flights
Every cancellation carries a reason code the operating carrier filed with US DOT. July 2023 – June 2026.
Endeavor Air cancelled 6,990 of 304,230 scheduled flights — about 1 in every 44. The reason it filed most often was the air traffic system, 50.9% of the cancellations it coded — about 1 in every 86 scheduled flights.
Share of cancellations
Of 6,990 cancelled departures carrying a reason code.
What each reason means
Airport capacity, air traffic control flow programmes, heavy traffic and ordinary bad weather. A system decision, not the airline’s.
3,555 cancellations, 50.9% of the total.
Conditions the carrier judged severe enough to stop the flight — a blizzard, a hurricane, a line of thunderstorms.
2,049 cancellations, 29.3% of the total.
Crew, maintenance, aircraft cleaning, baggage or fuelling — what BTS defines as within the carrier’s own control.
1,386 cancellations, 19.8% 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.
What these shares do not measure
A reason code is the operating carrier’s own filing. US DOT collects the reason the airline gave; it does not adjudicate it, and carriers differ in how they fill the form in. The split above describes what kind of disruption Endeavor Air records, not who was at fault when it happened, and it cannot be set against another airline’s split to decide which of the two is better run.
That is measurable rather than a disclaimer. Across the 15 carriers FlyerIntel publishes, the correlation between how much of its own cancelling a carrier attributes to itself and how often it actually cancels is -0.46 — negative, which is the wrong sign for a ranking of fault and about the right sign for a difference in filing convention. Hawaiian Airlines attributed 82.8% of its cancellations to itself and cancelled 1.00% of its flights; SkyWest Airlines attributed 2.5% and cancelled 1.33%. The airline taking the most blame is the one that cancels least.
The figure on this page that does compare cleanly between airlines is the cancellation rate in Reliability, because it counts cancellations instead of reading the reason filed for them. The First Flight of the Day sets out the same finding from the airport-carrier records, and declines on the strength of it to compare any two carriers’ codes.
Weather also sits inside the air traffic figure — code B covers only conditions severe enough to stop a flight outright, while ordinary bad weather is counted as an air traffic system cause — so weather’s full contribution is larger than the weather bar alone.
By airport
| Airport | Cancelled | Rate | Airline | Weather | Air traffic | Security |
|---|---|---|---|---|---|---|
| LGA New York | 1,767 | 3.59% | 15% | 31% | 53% | 0% |
| JFK New York | 997 | 3.78% | 13% | 27% | 60% | 0% |
Shares are of Endeavor Air’s own coded cancellations at each airport and run across the row, so they total 100%. “Rate” is cancellations as a share of its scheduled departures there. Reading down a column compares one airline with itself in different weather and different airspace, which is the comparison these codes support — a carrier files the same way wherever it flies, so its filing habits largely cancel out of the differences between these rows in a way they never cancel out of a comparison between two airlines. Airports where Endeavor Air recorded fewer coded cancellations than the published minimum are not listed.
Source: US DOT Bureau of Transportation Statistics · Data covering July 2023 – June 2026 · These are the reason codes Endeavor Air itself filed with US DOT — the reason the airline gave, not an independent finding of fault, and airlines differ in how they apply them. FlyerIntel publishes the split only for carriers with at least 500 coded cancellations in the period; 6,990 were recorded.

Each column is one month of Endeavor Air operations. The strongest single month of the period was October 2023 at 92.4% on time; the weakest was July 2024 at 71.1%. Individual months move for reasons that do not repeat — a hurricane season, a technology outage, a winter storm — which is why the section below combines the same data by calendar month instead.

Why Endeavor Air runs late
Share of total reported delay minutes by cause, as classified by the operating carrier.
the inbound aircraft was late, so this flight started late
crew, maintenance, boarding, fuelling — 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 Endeavor Air. A single late flight can carry more than one cause, and only delays of fifteen minutes or more are attributed at all.
The largest single category for Endeavor Air is late-arriving aircraft, at 38.4% of attributed minutes. The category squarely inside the carrier’s own control — crew, maintenance, boarding, fuelling — accounts for 31.9% of its delay minutes, against 34.0% across the 15 carriers covered here. That is 2.2 percentage points less of its delay minutes falling inside the airline than is typical for this group.
These shares describe how delay minutes were divided, not how often delays happened. A carrier with an unusually large air-traffic-control share is not necessarily worse run; it may simply fly more of its schedule through congested airspace. The one category that is squarely the airline’s own is the carrier category, which is why it is the one compared above.

Where this airline flies
Departure performance at the airports FlyerIntel covers.
Endeavor Air departed from 123 airports in this period, with no single one accounting for more than 16.2% of departures and the largest three together 37.3%. Performance is spread across the network rather than resting on one or two hubs, so a single weak airport moves this carrier’s overall figure less than it would at a hub-and-spoke airline.

Every carrier on FlyerIntel is measured the same way, over the same period, using the same source data. That is the whole point of the table: airline marketing reports punctuality on definitions of its own choosing, and this does not.

Data and methodology
Calculated by FlyerIntel from 304,230 Endeavor Air flight records published by the US DOT Bureau of Transportation Statistics, covering July 2023 – June 2026. A flight counts as delayed when it arrives 15 or more minutes after schedule. Cancelled and diverted flights are excluded from the on-time rate and reported separately, because folding them in would flatter a carrier that cancels rather than runs late. Figures below a published sample threshold are omitted rather than shown with a caveat.
