Historical statistics for July 2026, not live status or a forecast for this year’s July. For today’s conditions at ORD, see live FAA status.
ORD in July carries a cancellation problem, not just a delay problem: 4.2% of scheduled flights never operate, against 2.6% nationally. Of the ones that do fly, about seven flights in ten 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 33,010 flights, of which Envoy Air flew 4,794 at 80.4% on time.
Envoy Air is the most reliable of the seven carriers covered here at 80.4% on time across 4,794 flights.

ORD across all twelve months
These figures cover 33,010 departures from Chicago O'Hare International in July 2026. 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
July next to ORD's other months
Against ORD's own year, July ran level with the twelve-month rate of 70.8%, which makes it number six of twelve months, best first. Either side of it, June ran 71.3% on time and August 64.6%, 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 July
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 28 points, against 17 points between the best and worst carrier.
- 5am–8am3,937 flights86.1%
- 8am–11am6,851 flights83.5%

- 2pm–5pm6,079 flights66.6%
- 5pm–8pm5,589 flights58.1%
- 8pm–5am5,408 flights59.6%
Scale runs 50% to 90%.
The 5pm–8pm window is where this operation falls apart: 58.1% on time, against 86.1% for the 5am–8am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 8am–11am window is the busiest, with 6,851 flights scheduled in it.
Across the week, Wednesday is the strongest day at 77.5% on time and Friday the weakest at 64.8%, a spread of 13 points.
Carrier by carrier
Which airlines ran best at ORD in July
The choice of carrier is not cosmetic here. Envoy Air arrives on time 80.4% of the time; American Airlines manages 63.1%. Sample sizes sit next to every figure, because a two-point gap across 5,995 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| United Airlines | 9,377 | 72.9% | 86 min | 2.96% | C |

Delta Air Lines cancels 5.7% 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 July
Late-arriving aircraft accounts for 45% of the 763,000 delay minutes carriers reported here, and the remaining four split what is left.
- 45%Late-arriving aircraft
- 28%Carrier
- 18%National Airspace System
- 10%Extreme weather
- 0%Security
45% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 763,000 reported delay minutes here, that single category outweighs weather by 5 to one. The split is drawn from 763,394 reported delay minutes.
Cancellations run at 4.18%, against 2.62% nationally. That is about one flight in 25 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.
12.2% of arrivals land a full hour or more behind schedule, against 11.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
