Percentiles over 907 operations. Cancelled and diverted flights have no arrival time and are counted separately rather than as very late arrivals.
Why OO3808 runs late
Where US DOT attributed the delay minutes on this flight.
weather severe enough to stop this flight specifically
crew, maintenance, boarding, fuelling — within the carrier’s control
airspace and airport capacity, including weather-driven flow control
Share of the delay minutes US DOT attributed to each cause for OO3808 on SLC → MSO. 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 SLC → MSO
Same airports, same journey — and not the same odds of arriving on time.
| Flight | Airline | On time | Median arrival | Operations |
|---|---|---|---|---|
| OO4112 | SkyWest Airlines | 94.5% | 11 min early | 814 |
Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. Schedules change; confirm the departure still operates before booking around this.
Data and methodology
Calculated by FlyerIntel from 907 records of OO3808 operating SLC → MSO, 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.
