Why OO4674 runs late
Where US DOT attributed the delay minutes on this flight.
crew, maintenance, boarding, fuelling — within the carrier’s control
the inbound aircraft was late, so this flight started late
airspace and airport capacity, including weather-driven flow control
weather severe enough to stop this flight specifically
Share of the delay minutes US DOT attributed to each cause for OO4674 on DEN → RAP. A single late flight can carry more than one cause, and only delays of fifteen minutes or more are attributed at all.
Other departures on DEN → RAP
Same airports, same journey — and not the same odds of arriving on time.

| OO5265 | SkyWest Airlines | 77.1% | 6 min early | 787 |
| OO5303 | SkyWest Airlines | 75.6% | 8 min early | 693 |

Data and methodology
Calculated by FlyerIntel from 310 records of OO4674 operating DEN → RAP, published by the US DOT Bureau of Transportation Statistics. A flight counts as delayed when it arrives 15 or more minutes after schedule. Cancelled and diverted flights are excluded from the on-time rate and reported separately. Flight numbers are resolved as carrier plus number plus route, because the same number serves different routes over time.
