Historical statistics for November 2025, not live status or a forecast for this year’s November. For today’s conditions at ORD, see live FAA status.
ORD in November carries a cancellation problem, not just a delay problem: 5.6% of scheduled flights never operate, against 2.5% nationally. Of the ones that do fly, close to three flights in four arrive on time, worth a C− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 28,703 flights, of which Envoy Air flew 4,377 at 79.1% on time.
Envoy Air is the most reliable of the eight carriers covered here at 79.1% on time across 4,377 flights.

ORD across all twelve months
These figures cover 28,703 departures from Chicago O'Hare 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 ORD's other months
Against ORD's own year, November ran 2 points better than the twelve-month rate of 71.0%, which makes it number six of twelve months, best first. Cancellations are where November stands out: 5.59% of scheduled departures were called off, 2.1 times the airport's rate across the year. Either side of it, October ran 74.7% on time and December 61.0%, so a trip moved by a few weeks would have landed in a worse stretch.

Departure window
The best time of day to leave ORD in November
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 18 points, against 12 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am2,971 flights83.7%
- 8am–11am6,371 flights77.1%
- 11am–2pm4,771 flights74.4%
- 2pm–5pm5,464 flights72.1%
- 5pm–8pm5,085 flights65.7%
- 8pm–5am4,041 flights69.1%
Scale runs 55% to 90%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 83.7% of the time, against 65.7% for the evening window. That is 18 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8am–11am window is the busiest, with 6,371 flights scheduled in it.
Across the week, Thursday is the strongest day at 80.3% on time and Sunday the weakest at 59.2%. 21 points is a smaller lever than departure hour, but it is free.
Carrier by carrier
Which airlines ran best at ORD in November
The choice of carrier is not cosmetic here. Envoy Air arrives on time 79.1% of the time; Frontier Airlines manages 67.2%. Sample sizes sit next to every figure, because a two-point gap across 390 flights means less than a ten-point one.

SkyWest Airlines cancels 8.6% of what it schedules here, the highest in the table. A cancelled flight never appears in an on-time rate, so read that column alongside the punctuality one rather than after it.

Delay causes
What held ORD 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 593,000 reported delay minutes.
- 39%Late-arriving aircraft
- 25%Carrier
- 25%National Airspace System
- 10%Extreme weather
- 0%Security
39% 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 593,000 reported delay minutes here, that single category outweighs weather by 4 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 593,362 reported delay minutes.
Cancellations run at 5.59%, against 2.49% nationally. That is roughly one flight in twenty cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 11.6% of arrivals land a full hour or more behind schedule, against 7.8% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.
What to do with this
Flying from ORD in November
