Why OO3410 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 and fueling, all within the carrier’s control
weather severe enough to stop this flight specifically

Does a late aircraft delay this flight?
How often the plane that flies OO3410 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, OO3410 pushed back an average of 37 minutes late; when it came in on time or early, an average of 2 minutes early.
Matched by tail number to the aircraft’s previous flight into SAN: 614 of 634 departures. Unknown, cancelled or diverted inbounds and gaps over 12 hours are left out.
Against the network at the same turn length
| Share of departures | Inbound landed 15+ late | Left 15+ late after a late inbound | Left 15+ late after an on-time inbound |
|---|---|---|---|
| OO3410 | 27% | 72% | 7% |
| Network, same turn | 18% | 92% | 12% |
42 scheduled minutes on the ground leaves little slack, yet this flight has passed a late inbound on less often than the network does at the same turn.
The network row is every flight with a scheduled turn of 30 to 44 minutes. How often OO3410’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often OO3410 left 15 or more minutes late is lower than the network’s.

From pushback to gate
When it leaves SAN late, does that still matter by the time it reaches SMF?
OO3410 pushes back an average of 10.5 minutes late and reaches the gate at SMF an average of 8.5 minutes late. The 2.0 minutes between those two figures are slack the published schedule already carries, so a late pushback is partly, not fully, made up before the gate. It spends 22.6 minutes on the taxiways at SAN, 3.3 minutes longer than a typical SAN departure in the same hour.
On arrival at SMF, OO3410 spends 5.9 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 about what any arrival at SMF spends on the ground before reaching the gate.
Taxi-out is gate to wheels up and sits inside the scheduled block; the hourly comparison is 15,736 SAN departures. Taxi-in is landing to gate, set against 177,301 arrivals at SMF. More on taxi time.

The hour it leaves SAN
OO3410 has one departure time, 5:42 PM, so this is what that hour at SAN is worth.
On-time arrival rate. 15,736 departures from SAN are scheduled in the 5 PM–6 PM hour over the period, against 307,047 across the whole day.
