Why UA1175 runs late
Where US DOT attributed the delay minutes on this flight.
crew, maintenance, boarding and fueling, all within the carrier’s control
airspace and airport capacity, including weather-driven flow control
the inbound aircraft was late, so this flight started late

From pushback to gate
When it leaves SFO late, does that still matter by the time it reaches HNL?
UA1175 pushes back an average of 11.1 minutes late and reaches the gate at HNL an average of 2.4 minutes early. The 13.5 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. It spends 25.0 minutes on the taxiways at SFO, 2.5 minutes longer than a typical SFO departure in the same hour.
On arrival at HNL, UA1175 spends 6.8 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 1.5 minutes shorter than a typical HNL arrival (8.3 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 HNL. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 26,943 departures from SFO scheduled in the clock hour UA1175 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at HNL (186,355 flights), not just UA1175’s own. More on taxi time.

The hour it leaves SFO
Part of any flight’s record belongs to the clock rather than to the flight. UA1175 has one departure time, so this is what that time is worth.
On-time arrival rate. 26,943 departures from SFO are scheduled in the 9 AM–10 AM hour over the period, against 435,779 across the whole day.
UA1175 is scheduled out of SFO at 9:20 AM, in the 9 AM–10 AM bank. Departures from SFO in that hour arrive on time 82.7% of the time against 78.7% across the airport’s whole day — the slot alone is worth 4.0 points better before anything about this particular flight is considered.
The two airport figures cover every departure from SFO 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.

By day of week
Does UA1175 run worse on particular days?
Sunday is historically the most reliable day and Friday the least, a gap of 11.9 percentage points.

Other routes UA1175 has flown
A flight number is a slot in a schedule, and carriers reassign it. These are the other city pairs this number served in the analysis period.
| Route | Operated | Flights | On time |
|---|---|---|---|
| IAH→SFO Houston to San Francisco | February 5, 2026 | 1 | — |
Because the same number has served different journeys, the statistics above describe only the route UA1175 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. UA1175 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.
Data and methodology
Calculated by FlyerIntel from 1,127 records of UA1175 operating SFO → HNL, published by the US DOT Bureau of Transportation Statistics. A flight counts as delayed when it arrives 15 or more minutes after schedule. Cancelled and diverted flights are excluded from the on-time rate and reported separately. Flight numbers are resolved as carrier plus number plus route, because the same number serves different routes over time.
