Why flights are cancelled at ANC

Every cancellation carries a reason code filed by the airline that operated the flight. Departures, July 2023 – July 2026.

The airline accounts for 50.6% of cancelled departures from ANC — about 1 in every 171 scheduled departures. That is 25 points higher than the 25.8% recorded across every airport FlyerIntel covers.

Share of the delay minutes US DOT attributed to each cause for departures from ANC. Only delays of 15 minutes or more are attributed.

Of the 8,319 departures from ANC that left 15 or more minutes late and have a known inbound aircraft, 58% followed a flight that landed 15 or more minutes late. The other 42% 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%; ANC’s is the 26th lowest.

The late flight is the one the same aircraft flew into ANC 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 ANC 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 ANC

Departures from ANC by the weather at the airport in the hour they were scheduled to leave, July 2023 – July 2026.

11.3% of scheduled departures from ANC left in an hour of bad weather. 1.9% of them were cancelled, against 1.0% in normal conditions, and 72.9% of the ones that flew arrived on time, against 85.1%. Those hours held 19% of all cancelled departures. That is about 60 more cancellations than the normal-conditions rate would give.

Cancellations were highest in fog hours: 2.8% of 791 departures, 2.7 times the normal rate.

Airlines filed 47% of ANC’s coded cancellations under extreme weather. By the weather at the airport in the scheduled hour, 19% 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. Too few departures to score: thunderstorm (7), heavy rain (26).

This is the weather reported at ANC 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 99.7% 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.

Turning aircraft around at ANC

Time on the ground between one flight and the next of the same aircraft at ANC, and what a late arrival does to the next departure, July 2023 – July 2026.

The median turn at ANC is scheduled for 75 minutes on the ground and takes 81 minutes, against 56 minutes and 63 minutes across all airports. Aircraft are given longer on the ground here than at the typical airport. The 6 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 (9,579 turns here, 48 minutes late on average), 82% of the turns were finished in no more than the scheduled ground time, against 68% across all airports. 48% 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 82% finished in the schedule and 55% leaving late. ANC passes lateness on less often than the network would at these turn lengths, with late turns finished in the schedule about as often. 47% of its late-inbound turns had a scheduled turn of 60 to 89 minutes, against 29% across all airports.

The last column is the network’s rate at the turn lengths scheduled at ANC, 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 ANC with its next departure from it by tail number; the aircraft is never named. These 46,045 turns are 78% of the flights that left ANC 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 ANC and does not rate the airport.

"Elsewhere" is every other covered airport together, taken from the same aggregates as this page with ANC’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.
