Historical statistics for July 2025, not live status or a forecast for this year’s July. For today’s conditions at PIT, see live FAA status.

PIT in July carries a cancellation problem, not just a delay problem: 3.3% 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 B− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 3,959 flights, of which Republic Airways flew 1,036 at 80.5% on time.

Republic Airways is the most reliable of the three carriers covered here at 80.5% on time across 1,036 flights.

PIT across all twelve months

These figures cover 3,959 departures from Pittsburgh International in July 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

July next to PIT's other months

Against PIT's own year, July ran 5 points worse than the twelve-month rate of 81.4%, which makes it number eleven of twelve months, best first. Cancellations are where July stands out: 3.31% of scheduled departures were called off, 1.7 times the airport's rate across the year.

Departure window

The best time of day to leave PIT in July

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 36 points, against 11 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

  • 5am–8am1,107 flights92.0%
  • 8am–11am666 flights87.8%
  • 11am–2pm551 flights80.6%
  • 2pm–5pm546 flights66.3%
  • 5pm–8pm892 flights56.0%
  • 8pm–5am197 flights59.6%

Scale runs 50% to 95%. Rows with fewer than 30 flights show a dash.

The 5pm–8pm window is where this operation falls apart: 56.0% on time, against 92.0% 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 5am–8am window is the busiest, with 1,107 flights scheduled in it.

Across the week, Saturday is the strongest day at 81.8% on time and Sunday the weakest at 71.2%. 11 points is a smaller lever than departure hour, but it is free.

Carrier by carrier

Which airlines ran best at PIT in July

The choice of carrier is not cosmetic here. Republic Airways arrives on time 80.5% of the time; American Airlines manages 69.6%. Sample sizes sit next to every figure, because a two-point gap across 605 flights means less than a ten-point one.

Delay causes

What held PIT up in July

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 72,000 reported delay minutes.

  • Late-arriving aircraft
    39%
  • National Airspace System
    31%
  • Carrier
    25%
  • Extreme weather
    5%
  • Security
    0%

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 72,000 reported delay minutes here, that single category outweighs weather by 7 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 72,328 reported delay minutes.

Cancellations run at 3.31%, against 2.45% nationally. That is about one flight in 30 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. 9.6% of arrivals land a full hour or more behind schedule, against 12.1% 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 PIT in July

For a July trip through PIT: plan on this being one of the airport's harder months. The 5am–8am departures held up best at 92.0% on time, and with 9.6% of arrivals an hour or more late, a connection here deserves more slack than the same trip in September would.
