PDX in November earns a B. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 5 points better than the national rate of 79.4%. When something does go wrong the average delay runs about an hour. That rests on 4,976 flights, of which Delta Air Lines flew 587 at 90.5% on time.

Delta Air Lines is the most reliable of the five carriers covered here at 90.5% on time across 587 flights.

PDX across all twelve months

These figures cover 4,976 departures from Portland International in November 2025. On time means an arrival less than 15 minutes after the scheduled gate time, the DOT's threshold, and the national comparison uses every US departure in the same month rather than the whole year.

Against the year

November next to PDX's other months

Against PDX's own year, November ran 2 points better than the twelve-month rate of 82.6%, which makes it number five of twelve months, best first. Cancellations are where November stands out: 1.51% of scheduled departures were called off, 2.0 times the airport's rate across the year. Either side of it, October ran 82.1% on time and December 79.3%, so a trip moved by a few weeks would have landed in a worse stretch.

Departure window

The best time of day to leave PDX in November

Departure time is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 4,976 flights.

5am–8am1,273 flights84.8%
8am–11am835 flights85.7%
11am–2pm666 flights85.6%
2pm–5pm753 flights84.6%
5pm–8pm769 flights81.1%
8pm–5am680 flights82.8%

Scale runs 75% to 90%. Rows with fewer than 30 flights show a dash.

The early departures do better, though not dramatically: 85.7% on time for the 8am–11am window against 81.1% for 5pm–8pm. Worth taking if the schedule allows, not worth an extra connection. The 5am–8am window is the busiest, with 1,273 flights scheduled in it.

Across the week, Tuesday is the strongest day at 87.3% on time and Sunday the weakest at 81.5%. 6 points is a smaller lever than departure hour, but it is free.

Carrier by carrier

Which airlines ran best at PDX in November

The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 90.5% of the time; Southwest Airlines manages 80.9%. Sample sizes sit next to every figure, because a two-point gap across 635 flights means less than a ten-point one.

Delta leads Southwest by 10 points. Real, but small enough that a better departure time on the weaker carrier can outweigh it.

Delay causes

What held PDX up in November

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 45,000 reported delay minutes.

Late-arriving aircraft
35%
National Airspace System
32%
Carrier
30%
Extreme weather
3%
Security
0%

35% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 45,000 reported delay minutes here, that single category outweighs weather by 13 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 45,443 reported delay minutes.

Cancellations sit at 1.51% against a national 2.49%, which is ordinary. Diversions add another 0.18%.

Badly late arrivals are rare here: only 4.1% land an hour or more behind schedule, against 7.8% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
