The aircraft flying UA358 came in 15 or more minutes late on 14% 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 DFW just before it, using the tail number in the DOT file, 855 of 927 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.

UA358 pushes back an average of 11.3 minutes late and reaches the gate at IAD an average of 7.3 minutes late. The 4.0 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 17.1 minutes on the taxiways at DFW, 2.3 minutes shorter than a typical DFW departure in the same hour.

On arrival at IAD, UA358 spends 8.1 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 about what any arrival at IAD 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 IAD. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 74,916 departures from DFW scheduled in the clock hour UA358 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at IAD (169,930 flights), not just UA358’s own. More on taxi time.

UA358 is scheduled out of DFW at 12:15 PM, in the 12 PM–1 PM bank. Departures from DFW in that hour arrive on time 78.1% of the time against 73.1% across the airport’s whole day — the slot alone is worth 5.0 points better before anything about this particular flight is considered.

The two airport figures cover every departure from DFW 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 UA358 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. UA358 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.
