OO3736

OO3736 arrived on time 88.0% of the time, against 81.3% for all SEA → SJC flights, so this departure is 6.7 percentage points better than the route as a whole. Against SkyWest Airlines’ own flights on this route it is 1.3 points better.

OO3736’s scheduled departure has moved during the period FlyerIntel has on file: it typically left around 7:30 AM earlier on, and around 8:30 AM more recently — a 60-minute shift, not the few minutes of day-to-day rounding every published schedule carries. Confirm the current departure time before booking around an older listing.

The aircraft flying OO3736 came in 15 or more minutes late on 4% 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 SEA just before it, using the tail number in the DOT file, 673 of 768 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.

On arrival at SJC, OO3736 spends 3.4 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 SJC spends on the ground before reaching the gate.

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 42,963 departures from SEA scheduled in the clock hour OO3736 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 OO3736’s own. More on taxi time.

OO3736 is scheduled out of SEA at 7:25 AM, in the 7 AM–8 AM bank. Departures from SEA in that hour arrive on time 85.0% of the time against 79.1% across the airport’s whole day — the slot alone is worth 5.9 points better before anything about this particular flight is considered.

The two airport figures cover every departure from SEA 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 OO3736 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. OO3736 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.
