DEN across all twelve months

These figures cover 25,280 departures from Denver 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 DEN's other months

Against DEN's own year, November ran 8 points better than the twelve-month rate of 76.3%, which makes it the best of the twelve months in the data. Cancellations are where November stands out: 1.44% of scheduled departures were called off, 1.8 times the airport's rate across the year. Either side of it, October ran 80.8% on time and December 74.3%, so a trip moved by a few weeks would have landed in a worse stretch.

Departure window

The best time of day to leave DEN 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 25,000 flights.

5am–8am1,958 flights89.5%
8am–11am5,282 flights88.9%
11am–2pm5,801 flights86.8%
2pm–5pm3,587 flights82.4%
5pm–8pm5,264 flights80.1%
8pm–5am3,388 flights81.5%

Scale runs 70% to 95%. Rows with fewer than 30 flights show a dash.

Book the early departure. Flights leaving between 5am–8am arrive on time 89.5% of the time, against 80.1% for the evening window. That is 9 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 11am–2pm window is the busiest, with 5,801 flights scheduled in it.

Across the week, Wednesday is the strongest day at 90.6% on time and Sunday the weakest at 77.9%. 13 points is a smaller lever than departure hour, but it is free.

Carrier by carrier

Which airlines ran best at DEN in November

The choice of carrier is not cosmetic here. SkyWest Airlines arrives on time 90.1% of the time; Southwest Airlines manages 79.9%. Sample sizes sit next to every figure, because a two-point gap across 7,040 flights means less than a ten-point one.

Carriers at DEN in November 2025

United Airlines	8,428	85.2%	66 min	0.53%	A+
Southwest Airlines	7,040	79.9%	47 min	1.56%	B

Alaska Airlinesthin sample	212	79.5%	39 min	0.94%	B+
JetBlue Airwaysthin sample	62	70.5%	152 min	1.61%	C

SkyWest 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 DEN 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 233,000 reported delay minutes.

Late-arriving aircraft
38%
Carrier
35%
National Airspace System
24%
Extreme weather
3%

38% 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 233,000 reported delay minutes here, that single category outweighs weather by 11 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 232,991 reported delay minutes.

Cancellations sit at 1.44% against a national 2.49%, which is ordinary. Diversions add another 0.16%.

Badly late arrivals are rare here: only 4.5% 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.
