Departure window
The best time of day to leave PIT in June
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 29 points, against 11 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am1,009 flights92.4%
- 8am–11am639 flights91.4%
- 11am–2pm638 flights80.1%
- 2pm–5pm487 flights66.7%
- 5pm–8pm788 flights63.8%
- 8pm–5am254 flights63.3%
Scale runs 55% to 100%. Rows with fewer than 30 flights show a dash.
The 8pm–5am window is where this operation falls apart: 63.3% on time, against 92.4% 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 1,009 flights scheduled in it.
Across the week, Tuesday is the strongest day at 86.1% on time and Sunday the weakest at 73.1%. 13 points is a smaller lever than departure hour, but it is free.
Carrier by carrier
Which airlines ran best at PIT in June
The choice of carrier is not cosmetic here. Republic Airways arrives on time 84.4% of the time; United Airlines manages 73.4%. Sample sizes sit next to every figure, because a two-point gap across 373 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Republic Airways | 1,044 | 84.4% | 76 min | 2.59% | B |

Republic leads United by 11 points. Real, but small enough that a better departure time on the weaker carrier can outweigh it.

Delay causes
What held PIT up in June
One category carries most of the weight here. Late-arriving aircraft accounts for 43% of the 66,000 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.
- 43%Late-arriving aircraft
- 28%Carrier
- 24%National Airspace System
- 5%Extreme weather
- 0%Security
43% 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 66,000 reported delay minutes here, that single category outweighs weather by 9 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 66,465 reported delay minutes.
Cancellations sit at 1.68% against a national 1.65%, which is ordinary. Diversions add another 0.34%.
8.0% of arrivals land an hour or more late, close to the national 9.7%. 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 an hour and a half, which a normal layover absorbs.
