Share of the delay minutes US DOT attributed to each cause for UA739 on OMA → ORD. Only delays of 15 minutes or more are attributed.

When the aircraft came in 15 or more minutes late, UA739 pushed back an average of 72 minutes late; when it came in on time or early, an average of 5 minutes late.

Each departure is matched to the flight the same aircraft flew into OMA just before it, using the tail number in the DOT file, 765 of 771 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 ORD, UA739 spends 18.5 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 ORD 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 ORD. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 5,884 departures from OMA scheduled in the clock hour UA739 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at ORD (952,666 flights), not just UA739’s own. More on taxi time.

UA739 is scheduled out of OMA at 3:27 PM, in the 3 PM–4 PM bank. Departures from OMA in that hour arrive on time 78.2% of the time against 81.7% across the airport’s whole day — the slot alone is worth 3.5 points worse before anything about this particular flight is considered.

The two airport figures cover every departure from OMA 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 UA739 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. UA739 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.
