Delay causes
Why OO 3472 runs late
Late-arriving aircraft accounts for 50% of the 2,783 delay minutes carriers reported here, and the remaining four split what is left.
- 50%Late-arriving aircraft
- 33%National Airspace System
- 11%Carrier
- 6%Extreme weather
50% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 2,783 reported delay minutes here, that single category outweighs weather by 9 to one. The split is drawn from 2,783 delay minutes reported on OO 3472.
Cancellations run at 4.91%, against 1.89% nationally. That is about one flight in twenty cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 1.3% land an hour or more behind schedule, against 8.3% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
Every one of the 326 flights under OO 3472 in the data flew SAN to FAT. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 326 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.
What to do with this
Booking OO 3472
For a booking, the cancellation rate is the figure to plan around on OO 3472: 4.91% of its 326 scheduled flights did not operate. A late arrival costs about 35 minutes, but a cancellation costs the day, so leave a later option open.
