Share of the delay minutes US DOT attributed to each cause for UA1806 on HNL → DEN. Only delays of 15 minutes or more are attributed.

When the aircraft came in 15 or more minutes late, UA1806 pushed back an average of 37 minutes late; when it came in on time or early, an average of 4 minutes late.

Each departure is matched to the flight the same aircraft flew into HNL just before it, using the tail number in the DOT file, 651 of 663 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.

UA1806 pushes back an average of 16.2 minutes late and reaches the gate at DEN an average of 6.3 minutes late. The 9.9 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 20.2 minutes on the taxiways at HNL, 2.4 minutes longer than a typical HNL departure in the same hour.

On arrival at DEN, UA1806 spends 8.6 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 1.1 minutes shorter than a typical DEN arrival (9.8 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 DEN. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 8,074 departures from HNL scheduled in the clock hour UA1806 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at DEN (963,027 flights), not just UA1806’s own. More on taxi time.

UA1806 is scheduled out of HNL at 9:50 PM, in the 9 PM–10 PM bank. Departures from HNL in that hour arrive on time 85.6% of the time against 85.3% across the airport’s whole day, so the hour UA1806 leaves in is an ordinary one for HNL and explains nothing about its record either way.

The two airport figures cover every departure from HNL 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 UA1806 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. UA1806 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.
