Why OO6290 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
screening or terminal security incidents

Does a late aircraft delay this flight?
How often the plane that flies OO6290 comes in late, and what that does to the departure.
OO6290 is usually the aircraft’s first flight of the day: the schedule gives it a median of 8.4 hours on the ground at PDX, so its “inbound” is mostly the aircraft’s arrival the evening before.
When the aircraft came in 15 or more minutes late, OO6290 pushed back an average of 3 minutes late; when it came in on time or early, an average of 3 minutes early.
Each departure is matched to the flight the same aircraft flew into PDX just before it, using the tail number in the DOT file, 568 of 609 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 | Left 15+ late after a late inbound | Left 15+ late after an on-time inbound |
|---|---|---|---|
| OO6290 | 24% | 11% | 5% |
| Network, same turn | 29% | 12% | 9% |
A night on the ground absorbs most of a late arrival, so a late inbound matters far less on a turn this long than on a same-day one.
The network row is every flight with a scheduled turn of 6 hours or more, usually overnight. How often OO6290’s aircraft landed 15 or more minutes late is lower than the network’s and, once the aircraft was late, how often OO6290 left 15 or more minutes late is about the same as the network’s.

From pushback to gate
When it leaves PDX late, does that still matter by the time it reaches LAX?
OO6290 pushes back an average of 5.5 minutes late and reaches the gate at LAX an average of 3.2 minutes late. The 2.3 minutes between those two figures are slack the published schedule already carries, which is why a late pushback on this flight does not reliably become a late arrival. It spends 18.4 minutes on the taxiways at PDX, 4.5 minutes longer than a typical PDX departure in the same hour.
On arrival at LAX, OO6290 spends 16.0 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 5.2 minutes longer than a typical LAX arrival (10.7 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 LAX. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 11,314 departures from PDX scheduled in the clock hour OO6290 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at LAX (595,170 flights), not just OO6290’s own. More on taxi time.

The hour it leaves PDX
Part of any flight’s record belongs to the clock rather than to the flight. OO6290 has one departure time, so this is what that time is worth.
On-time arrival rate. 11,314 departures from PDX are scheduled in the 6 AM–7 AM hour over the period, against 187,633 across the whole day.
OO6290 is scheduled out of PDX at 6:00 AM, in the 6 AM–7 AM bank. Departures from PDX in that hour arrive on time 93.1% of the time against 83.2% across the airport’s whole day — the slot alone is worth 9.9 points better before anything about this particular flight is considered.
The two airport figures cover every departure from PDX 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.

Other routes OO6290 has flown
A flight number is a slot in a schedule, and carriers reassign it. These are the other city pairs this number served in the analysis period.
| Route | Operated | Flights | On time |
|---|---|---|---|
| DFW→SAF Dallas–Fort Worth to Santa Fe | June 5, 2024 – August 5, 2024 | 58 | — |
| SAF→DFW Santa Fe to Dallas–Fort Worth | June 5, 2024 – August 5, 2024 | 57 | — |
Because the same number has served different journeys, the statistics above describe only the route OO6290 currently operates. Blending them would produce an average of two different flights.

Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. OO6290 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 612 records of OO6290 operating PDX → LAX, 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.
