Why flights are cancelled at PDX
Every cancellation carries a reason code filed by the airline that operated the flight. Departures, July 2023 – July 2026.
The airline accounts for 56.5% of cancelled departures from PDX — about 1 in every 206 scheduled departures. That is 31 points higher than the 25.8% recorded across every airport FlyerIntel covers.
Share of cancellations
Of 1,612 cancelled departures carrying a reason code.
What each reason means
Crew, maintenance, aircraft cleaning, baggage or fueling: what BTS counts as within the carrier’s own control.
911 cancellations, 56.5% of the total.
Conditions the carrier judged severe enough to stop the flight: a blizzard, a hurricane, a line of thunderstorms.
609 cancellations, 37.8% of the total.
Airport capacity, air traffic control flow programs, heavy traffic and ordinary bad weather. A system decision, not the airline’s.
92 cancellations, 5.7% 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.
1,612 of 187,633 scheduled departures from PDX 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 PDX
Where US DOT attributed the delay minutes on departures from PDX.
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 PDX. Only delays of 15 minutes or more are attributed.
Of the 26,679 departures from PDX that left 15 or more minutes late and have a known inbound aircraft, 59% followed a flight that landed 15 or more minutes late. The other 41% 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%; PDX’s is the 29th lowest.
The late flight is the one the same aircraft flew into PDX 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 PDX 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 PDX
Departures from PDX by the weather at the airport in the hour they were scheduled to leave, July 2023 – July 2026.
6.0% of scheduled departures from PDX left in an hour of bad weather. 1.7% of them were cancelled, against 0.8% in normal conditions, and 84.6% of the ones that flew arrived on time, against 83.0%. Those hours held 12% of all cancelled departures. That is about 105 more cancellations than the normal-conditions rate would give.
Cancellations were highest in high wind hours: 5.9% of 679 departures, 7.7 times the normal rate.
Airlines filed 38% of PDX’s coded cancellations under extreme weather. By the weather at the airport in the scheduled hour, 12% 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 PDX 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 PDX
Cancellations by airline in hours of bad weather at PDX, against the other carriers in the same months, July 2023 – July 2026.
6% of the weather-matched departures from PDX left in an hour of bad weather at the airport. 1.7% of them were cancelled. That is 2.2 times the 0.8% in normal hours. No one carrier holds most of them; 6 airlines have enough to compare.
Compared with the other carriers at PDX in the same months, Delta Air Lines (0.8% cancelled against 1.9% for the others; level with them in normal hours, so a bad-weather difference) cancelled the fewest in bad weather and Alaska Airlines (2.1% cancelled against 1.2% for the others; level with them in normal hours, so a bad-weather difference) the most.
Airlines in bad weather at PDX
Scheduled departures, July 2023 – July 2026| Airline | Bad-weather departures | Cancelled | Other carriers | Normal hours |

| Alaska Airlines | 4,00335% of bad-weather | 2.1%above the others | 1.2% | 0.9%others 0.7% |
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 6 listed airlines flew 95% of the bad-weather departures at PDX; 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. SkyWest Airlines flies for Delta Air Lines, United Airlines, American Airlines and Alaska 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 PDX
Time on the ground between one flight and the next of the same aircraft at PDX, and what a late arrival does to the next departure, July 2023 – July 2026.
The median turn at PDX is scheduled for 60 minutes on the ground and takes 64 minutes, against 56 minutes and 63 minutes across all airports. Aircraft are given longer on the ground here than at the typical airport. The typical turn runs 4 minutes over its schedule, closer to it than the 7 minutes across all airports. 16.8% of turns here began with an aircraft that landed 15 or more minutes late, below the 18.9% for all airports.
When the aircraft landed 15 or more minutes late (22,624 turns here, 52 minutes late on average), 75% of the turns were finished in no more than the scheduled ground time, against 68% across all airports. 66% of those flights left 15 or more minutes late, against 72%. After an aircraft that landed on time, 8% did (all airports 11%).
Given the turn lengths scheduled here, the network’s rates would give 70% finished in the schedule and 69% leaving late. PDX does better on both counts: more late turns are finished in the schedule and fewer late aircraft become late departures, so the turn recovers lateness here beyond what the schedule explains. 37% of its late-inbound turns had a scheduled turn of 60 to 89 minutes, against 29% across all airports.
Turns at PDX against all airports

| Turns that began with an aircraft 15+ minutes late | 17% | 19% | — |
| Late turns finished within the schedule | 75% | 68% | 70% |
| Late inbound that left 15+ minutes late | 66% | 72% | 69% |
| On-time inbound that left 15+ minutes late | 8% | 11% | — |
The last column is the network’s rate at the turn lengths scheduled at PDX, 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 PDX with its next departure from it by tail number; the aircraft is never named. These 134,838 turns are 72% of the flights that left PDX 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 PDX and does not rate the airport.

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

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, PDX’s busiest hall, both passport queues run much the same: a typical 11 min on a US passport and 14 min on any other, rising to 25 min on a busy day. Where the two halls agree like this, CBP’s combined figure of 12 min is a fair summary of both — which is not true everywhere, and is why they are shown apart.
Terminal by terminal, across the day

US passports: clearing in the 9 PM–10 PM hour typically takes 13 min, against 7 min in the 7 PM–8 PM hour — 6 min between the slowest and fastest of 8 measured hours.
All other passports: clearing in the 11 AM–12 PM hour typically takes 22 min, against 9 min in the 7 PM–8 PM hour — 13 min between the slowest and fastest of 8 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 7 AM, with about 21 departures a day, against roughly 4 at 8 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.
