Historical statistics for November 2025, not live status or a forecast for this year’s November. For today’s conditions at MDW, see live FAA status.
MDW in November carries a cancellation problem, not just a delay problem: 5.0% of scheduled flights never operate, against 2.5% nationally. Of the ones that do fly, about four flights in five arrive on time, worth a B− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 5,620 flights, with a median arrival 7 minutes early.

MDW across all twelve months
These figures cover 5,620 departures from Chicago Midway 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 MDW's other months
Against MDW's own year, November ran 6 points better than the twelve-month rate of 75.1%, which makes it number four of twelve months, best first. Cancellations are where November stands out: 4.96% of scheduled departures were called off, 3.3 times the airport's rate across the year. Either side of it, October ran 80.2% on time and December 69.7%, so a trip moved by a few weeks would have landed in a worse stretch.

Departure window
The best time of day to leave MDW in November
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 16 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am659 flights87.8%
- 8am–11am1,491 flights87.7%
- 11am–2pm961 flights83.2%
- 2pm–5pm748 flights76.4%
- 5pm–8pm1,018 flights72.5%
- 8pm–5am743 flights71.5%
Scale runs 65% to 95%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 87.8% of the time, against 71.5% for the overnight window. That is 16 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 1,491 flights scheduled in it.
Across the week, Friday is the strongest day at 88.7% on time and Sunday the weakest at 64.5%. 24 points is a smaller lever than departure hour, but it is free.

Delay causes
What held MDW 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 61,000 reported delay minutes.
- 40%Late-arriving aircraft
- 30%Carrier
- 28%National Airspace System
- 1%Extreme weather
- 1%Security
40% 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 61,000 reported delay minutes here, that single category outweighs weather by 28 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 61,397 reported delay minutes.
Cancellations run at 4.96%, against 2.49% nationally. That is about 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.
6.3% of arrivals land an hour or more late, close to the national 7.8%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.
