OO3745 is usually the aircraft’s first flight of the day: the schedule gives it a median of 8.3 hours on the ground at TUS, so its “inbound” is mostly the aircraft’s arrival the evening before.

The aircraft flying OO3745 came in 15 or more minutes late on 13% 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 TUS just before it, using the tail number in the DOT file, 773 of 785 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.

OO3745 pushes back an average of 5.4 minutes early and reaches the gate at SLC an average of 14.8 minutes early. The 9.4 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 14.8 minutes on the taxiways at TUS, 1.4 minutes longer than a typical TUS departure in the same hour.

On arrival at SLC, OO3745 spends 7.6 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 SLC 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 SLC. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 7,217 departures from TUS scheduled in the clock hour OO3745 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at SLC (355,118 flights), not just OO3745’s own. More on taxi time.

OO3745 is scheduled out of TUS at 6:00 AM, in the 6 AM–7 AM bank. Departures from TUS in that hour arrive on time 93.3% of the time against 84.3% across the airport’s whole day — the slot alone is worth 9.1 points better before anything about this particular flight is considered.

The two airport figures cover every departure from TUS 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 OO3745 currently operates. Blending them would produce an average of two different flights.
