Why OO3359 runs late
Where US DOT attributed the delay minutes on this flight.
the inbound aircraft was late, so this flight started late
crew, maintenance, boarding and fueling, all within the carrier’s control
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 OO3359 on SAN → SJC. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies OO3359 comes in late, and what that does to the departure.
The aircraft flying OO3359 came in 15 or more minutes late on 15% of the departures where its previous flight is known. There are not enough departures in both groups to say how the flight left after a late one and after an on-time one.
Each departure is matched to the flight the same aircraft flew into SAN just before it, using the tail number in the DOT file, 679 of 703 departures in all. A departure is left out when that flight is unknown, was cancelled or diverted, or the aircraft had sat for more than 12 hours. A flight the airline cancelled never left and is not in the count, and one flown by a substitute aircraft is matched to the aircraft that flew it, not to the one first planned.
Against the network at the same turn length
| Share of departures | Inbound landed 15+ late |
|---|---|
| OO3359 | 15% |
| Network, same turn | 18% |
The schedule leaves little slack between the inbound landing and this departure, so a late arrival has almost nowhere to go but into the departure.
The network row is every flight with a scheduled turn of 30 to 44 minutes. How often OO3359’s aircraft landed 15 or more minutes late is lower than the network’s. There are not enough departures in both groups to compare how it left.

From pushback to gate
When it leaves SAN late, does that still matter by the time it reaches SJC?
On arrival at SJC, OO3359 spends 5.5 min taxiing from touchdown to the gate — ground time a connecting passenger sits through before they can even leave the aircraft, on top of however late the flight itself ran. That is 1.4 minutes longer than a typical SJC arrival (4.1 min).
Departure delay is averaged over every pushback and arrival delay over every completed arrival, so the two counts differ by the flights that never reached SJC. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 23,995 departures from SAN scheduled in the clock hour OO3359 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at SJC (146,904 flights), not just OO3359’s own. More on taxi time.

The hour it leaves SAN
Part of any flight’s record belongs to the clock rather than to the flight. OO3359 has one departure time, so this is what that time is worth.
On-time arrival rate. 23,995 departures from SAN are scheduled in the 8 AM–9 AM hour over the period, against 297,668 across the whole day.
OO3359 is scheduled out of SAN at 8:01 AM, in the 8 AM–9 AM bank. Departures from SAN in that hour arrive on time 81.7% of the time against 77.9% across the airport’s whole day — the slot alone is worth 3.8 points better before anything about this particular flight is considered.
The two airport figures cover every departure from SAN to every destination, so they describe the slot rather than this journey — the like-for-like comparison against the route is above. Hours are scheduled local, and a number whose schedule moved between banks inside the period has no single hour and is not described here at all. Why the hour matters.

Because the same number has served different journeys, the statistics above describe only the route OO3359 currently operates. Blending them would produce an average of two different flights.

Same airports, same journey, different odds of arriving on time.
| Flight | Airline | On time | Median arrival | Operations |
|---|---|---|---|---|

Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. OO3359 is placed in the same ordering rather than left out of it; the rows around it are the most punctual departures on the route, not all of them, so this is a comparison and not a rank. Schedules change; confirm the departure still operates before booking around this.
Data and methodology
Calculated by FlyerIntel from 705 records of OO3359 operating SAN → SJC, 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.
