Best time to fly out of Albert J Ellis (OAJ)
Albert J Ellis did not fly enough departures in this window to split the day into time bands. Not enough flights to say. A percentage needs at least 100 flights behind it before it is worth printing; anything thinner is noise wearing a decimal point. These are historical odds, not forecasts. The records say what happened on this schedule over three years; they know nothing about tomorrow’s thunderstorm.

Airlines at OAJ
Every airline with at least 100 departures from OAJ, busiest first. These are that airline’s departures from this airport only — its record across the country sits on its own page.
| Airline | Left on time | Typical delay | Cancelled | Departures |
|---|---|---|---|---|
| PSA Airlines | 81% | 95 min | 2.9% | 1,580 |
| Endeavor Air | 89.1% | 108 min | 0% | 686 |

Endeavor Air (through December 2024) stopped filing before June 2026. Its row covers a shorter run of months than the rest of the table, so its figure is not set against the others anywhere on this page.
What delays out of OAJ were put down to
Airlines file a reason with every arrival running 15 minutes late or more. Across 530 flights that departed OAJ and ran 15 minutes late or more, the delay minutes break down with 45.2% put down to airline operations and 35.4% to late-arriving aircraft.
- Late-arriving aircraft 35.4%
- Airline operations 45.2%
- Air traffic & airport volume 8.7%
- Severe weather 10.7%
- Security 0%
Late-arriving aircraft is the knock-on category: the plane came in late, so it went out late again. It is why a 7am problem in Newark is still a problem in Denver at dinnertime, and why it is usually the biggest slice on the bar.
