Because the same number has served different journeys, the statistics above describe only the route OO3492 currently operates. Blending them would produce an average of two different flights.
When it goes wrong
The average describes a usual day. This is the day that ruins a connection.
36 min late
against a median of 4 min early
Percentiles over 344 operations. Cancelled and diverted flights have no arrival time and are counted separately rather than as very late arrivals.
Why OO3492 runs late
Where US DOT attributed the delay minutes on this flight.
the inbound aircraft was late, so this flight started late
airspace and airport capacity, including weather-driven flow control
crew, maintenance, boarding, fuelling — within the carrier’s control
Share of the delay minutes US DOT attributed to each cause for OO3492 on SFO → SNA. 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 SFO → SNA
Same airports, same journey — and not the same odds of arriving on time.
| Flight | Airline | On time | Median arrival | Operations |
|---|---|---|---|---|
| OO5440 | SkyWest Airlines | 79.1% | 7 min early | 888 |
| OO3494 | SkyWest Airlines | 75.9% | 3 min early | 636 |
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 344 records of OO3492 operating SFO → SNA, 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.
