Departure window
The best time of day to leave PIT in August
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 24 points, against 10 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am1,051 flights93.1%
- 8am–11am653 flights89.0%
- 11am–2pm538 flights85.2%
- 2pm–5pm646 flights75.4%
- 5pm–8pm801 flights69.4%
- 8pm–5am152 flights72.8%
Scale runs 60% to 100%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 93.1% of the time, against 69.4% for the evening window. That is 24 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 5am–8am window is the busiest, with 1,051 flights scheduled in it.
Across the week, Tuesday is the strongest day at 89.1% on time and Thursday the weakest at 79.0%. 10 points is a smaller lever than departure hour, but it is free.
Carrier by carrier
Which airlines ran best at PIT in August
The choice of carrier is not cosmetic here. Republic Airways arrives on time 87.5% of the time; American Airlines manages 77.9%. Sample sizes sit next to every figure, because a two-point gap across 540 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Republic Airways | 1,027 | 87.5% | 59 min | 1.27% | A |

Delay causes
What held PIT up in August
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 49,000 reported delay minutes.
- 41%Late-arriving aircraft
- 29%National Airspace System
- 27%Carrier
- 3%Extreme weather
- 0%Security
41% 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 49,000 reported delay minutes here, that single category outweighs weather by 13 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 49,142 reported delay minutes.
Cancellations sit at 1.20% against a national 1.08%, which is ordinary. Diversions add another 0.42%.
6.5% of arrivals land an hour or more late, close to the national 8.2%. 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 a little over an hour, which a normal layover absorbs.
