Why flights are cancelled at PHX

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

Extreme weather accounts for 56.7% of cancelled departures from PHX — about 1 in every 264 scheduled departures. That is close to the split across every airport FlyerIntel covers.

Shares are of each carrier’s own coded cancellations at PHX 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.

Source: US DOT Bureau of Transportation Statistics · Data covering July 2023 – July 2026 · Reason codes are each airline’s own filing, not an independent finding of fault. Shown for airports with at least 500 coded cancellations; 3,995 were recorded at PHX.

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

Of the 104,284 departures from PHX that left 15 or more minutes late and have a known inbound aircraft, 54% followed a flight that landed 15 or more minutes late. The other 46% 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%; PHX’s is the 13th lowest.

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

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

1.0% of scheduled departures from PHX left in an hour of bad weather. 2.5% of them were cancelled, against 0.6% in normal conditions, and 53.7% of the ones that flew arrived on time, against 80.6%. Those hours held 4% of all cancelled departures. That is about 116 more cancellations than the normal-conditions rate would give.

Cancellations were highest in thunderstorm hours: 4.5% of 2,351 departures, 7.0 times the normal rate.

Airlines filed 57% of PHX’s coded cancellations under extreme weather. By the weather at the airport in the scheduled hour, 4% 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 PHX 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.

Turning aircraft around at PHX

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

The median turn at PHX is scheduled for 57 minutes on the ground and takes 64 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 (80,164 turns here, 53 minutes late on average), 70% of the turns were finished in no more than the scheduled ground time, against 68% across all airports. 68% of those flights left 15 or more minutes late, against 72%. After an aircraft that landed on time, 11% did (all airports 11%).

Given the turn lengths scheduled here, the network’s rates would give 69% finished in the schedule and 70% leaving late. PHX passes lateness on less often than the network would at these turn lengths, with late turns finished in the schedule about as often.

Turns at PHX against all airports

471,687 turns, July 2023 – July 2026

Aircraft turns at PHX against all airports: scheduled and actual time on the ground and what a late inbound aircraft does

The last column is the network’s rate at the turn lengths scheduled at PHX, 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 PHX with its next departure from it by tail number; the aircraft is never named. These 471,687 turns are 79% of the flights that left PHX 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 PHX’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.

International arrivals

How long passport control normally takes here, hour by hour and hall by hall. This is the arrivals queue, not departure security — and it is history, not a live wait.

At Main, PHX’s busiest hall, both passport queues run much the same: a typical 4 min on a US passport and 7 min on any other, rising to 21 min on a busy day. Where the two halls agree like this, CBP’s combined figure of 5 min is a fair summary of both — which is not true everywhere, and is why they are shown apart.

US passports: clearing in the 7 AM–8 AM hour typically takes 10 min, against 2 min in the 9 AM–10 AM hour — 8 min between the slowest and fastest of 14 measured hours.

All other passports: clearing in the 7 AM–8 AM hour typically takes 14 min, against 3 min in the 4 PM–5 PM hour — 11 min between the slowest and fastest of 14 measured hours.

The hour is when CBP processed the passenger, not when the aircraft landed — allow for the walk from the gate. Hours with fewer than 120 days of records are not listed rather than shown as an estimate, which is why a terminal’s quietest hours are usually absent. “Busy day” is the 90th percentile: one arrival in ten is worse than that. Booths are how many CBP had open, and they follow the queue rather than prevent it — the busiest hours are staffed hardest and are still the slowest.

Source: US Customs and Border Protection · 2024-08-28 to 2026-10-16 · These are CBP passport control waits for arriving international passengers — a different queue from TSA departure screening. CBP publishes them about two days in arrears, so every figure here describes what has been typical over 2024-08-28 to 2026-10-16, and none of it is a live queue or a forecast for your flight. US and non-US passengers are reported separately by CBP and are kept separate here, because they are separate halls. FlyerIntel publishes a terminal or an hour only where CBP filed at least 120 hourly records for it, and an hour-by-hour breakdown only where at least 6 hours clear that floor.

The busiest hour is 8 AM, with about 46 departures a day, against roughly 18 at 9 PM. That peak is also more punctual than a typical hour here: early banks fly aircraft that spent the night on the ground rather than ones inheriting the day’s delays.
