The aircraft flying UA1003 came in 15 or more minutes late on 9% 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 DEN just before it, using the tail number in the DOT file, 546 of 709 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 CHS, UA1003 spends 8.9 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 1.2 minutes longer than a typical CHS arrival (7.7 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 CHS. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 70,565 departures from DEN scheduled in the clock hour UA1003 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at CHS (77,396 flights), not just UA1003’s own. More on taxi time.

UA1003 is scheduled out of DEN at 9:45 AM, in the 9 AM–10 AM bank. Departures from DEN in that hour arrive on time 82.6% of the time against 76.0% across the airport’s whole day — the slot alone is worth 6.6 points better before anything about this particular flight is considered.

The two airport figures cover every departure from DEN 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 UA1003 currently operates. Blending them would produce an average of two different flights.
