Why OO4811 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
weather severe enough to stop this flight specifically
airspace and airport capacity, including weather-driven flow control
screening or terminal security incidents
Share of the delay minutes US DOT attributed to each cause for OO4811 on PHX → SGU. A single late flight can carry more than one cause, and only delays of fifteen minutes or more are attributed at all.
Data and methodology
Calculated by FlyerIntel from 452 records of OO4811 operating PHX → SGU, 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.
