Departure window
The best time of day to leave PHL in June
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 26 points, against 14 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am990 flights88.8%
- 8am–11am2,193 flights84.7%
- 11am–2pm1,458 flights77.3%
- 2pm–5pm1,651 flights67.5%
- 5pm–8pm2,027 flights62.9%
- 8pm–5am1,388 flights69.2%
Scale runs 55% to 95%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 62.9% on time, against 88.8% 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 2,193 flights scheduled in it.
Across the week, Tuesday is the strongest day at 83.4% on time and Thursday the weakest at 66.0%. 17 points is a smaller lever than departure hour, but it is free.
Carrier by carrier
Which airlines ran best at PHL in June
The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 82.8% of the time; Southwest Airlines manages 68.8%. Sample sizes sit next to every figure, because a two-point gap across 440 flights means less than a ten-point one.

| American Airlines | 4,706 | 72.9% | 85 min | 1.91% | C |

PSA Airlines cancels 6.5% 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 PHL up in June
One category carries most of the weight here. Late-arriving aircraft accounts for 42% of the 203,000 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.
- 42%Late-arriving aircraft
- 31%Carrier
- 21%National Airspace System
- 6%Extreme weather
- 0%Security
42% 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 203,000 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 203,135 reported delay minutes.
Cancellations run at 2.73%, against 1.65% nationally. That is roughly one flight in 40 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. 10.2% of arrivals land a full hour or more behind schedule, against 9.7% 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.
