Why OO4908 runs late
Where US DOT attributed the delay minutes on this flight.
crew, maintenance, boarding and fueling, all within the carrier’s control
the inbound aircraft was late, so this flight started late
airspace and airport capacity, including weather-driven flow control
weather severe enough to stop this flight specifically
screening or terminal security incidents

Does a late aircraft delay this flight?
How often the plane that flies OO4908 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, OO4908 pushed back an average of 42 minutes late; when it came in on time or early, an average of 0 minutes early.
Matched by tail number to the aircraft’s previous flight into LAX: 584 of 611 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 |
|---|---|---|---|
| OO4908 | 21% | 51% | 5% |
| Network, same turn | 18% | 85% | 10% |
56 scheduled minutes is enough to clean and board when the aircraft is on time, with little to spare when it is not.
The network row is every flight with a scheduled turn of 45 to 59 minutes. How often OO4908’s aircraft landed 15 or more minutes late is about the same as the network’s and, once the aircraft was late, how often OO4908 left 15 or more minutes late is lower than the network’s.

From pushback to gate
When it leaves LAX late, does that still matter by the time it reaches SMF?
OO4908 pushes back an average of 14.6 minutes late and reaches the gate at SMF an average of 9.3 minutes late. The 5.2 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. Its 16.9 minutes on the taxiways at LAX is about what any departure from the airport in that hour spends.
On arrival at SMF, OO4908 spends 6.8 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 1.6 minutes longer than a typical SMF arrival (5.1 min).
Taxi-out is gate to wheels up and sits inside the scheduled block; the hourly comparison is 18,060 LAX departures. Taxi-in is landing to gate, set against 177,301 arrivals at SMF. More on taxi time.
