When the aircraft came in 15 or more minutes late, UA2665 pushed back an average of 44 minutes late; when it came in on time or early, an average of 7 minutes late.

Each departure is matched to the flight the same aircraft flew into ORD just before it, using the tail number in the DOT file, 754 of 878 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.

UA2665 pushes back an average of 23.0 minutes late and reaches the gate at IAH an average of 11.5 minutes late. The 11.5 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. Its 26.3 minutes on the taxiways at ORD is about what any departure from the airport in that hour spends.

On arrival at IAH, UA2665 spends 7.1 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 3.6 minutes shorter than a typical IAH 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 IAH. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 36,773 departures from ORD scheduled in the clock hour UA2665 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at IAH (359,471 flights), not just UA2665’s own. More on taxi time.

UA2665 is scheduled out of ORD at 9:15 PM, in the 9 PM–10 PM bank. Departures from ORD in that hour arrive on time 67.6% of the time against 74.5% across the airport’s whole day — the slot alone is worth 7.0 points worse before anything about this particular flight is considered.

The two airport figures cover every departure from ORD 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 UA2665 currently operates. Blending them would produce an average of two different flights.
