These figures cover 365 flights between July 2025 and June 2026. The median arrival is 9 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Schedule

When UA 1175 flies

UA 1175 flies SFO to HNL without a single fixed slot. Its most common scheduled departure was 09:20, used on 180 of 365 flights, with 09:30 (111 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 09:20 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and UA 1175 runs 8 points better at 91.7%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Against the route

UA 1175 next to SFO to HNL

United flew 1,742 flights on the same city pair under all its flight numbers, including this one, and those ran 86.5% on time. Across its whole network United Airlines managed 79.0%, which this flight beats by 13 points.

Across the year

UA 1175 quarter by quarter

UA 1175 did not run the same all year. Its best quarter was Jan–Mar 2026 at 97.8% on time and its weakest Apr–Jun 2026 at 84.6%, a swing of 13 points on roughly 91 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

By weekday, UA 1175 did best on Tuesday at 98.1% on time and worst on Friday at 82.7%. Each day rests on about 52 flights, so a gap of 15 points is worth noticing but could still narrow in another year.

Delay causes

Why UA 1175 runs late

One category carries most of the weight here. Carrier accounts for 76% of the 1,830 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

76%
National Airspace System
24%
Late-arriving aircraft
0%

The largest share of delay minutes, 76%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 1,392 of the 1,830 delay minutes reported here. The split is drawn from 1,830 delay minutes reported on UA 1175.

Cancellations are rare at 0.55%, below the national 1.81% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 2.8% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.

At 2,398 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.

The same number turns up on one other city pair in the data, including IAH to SFO (1), but none flew often enough under UA 1175 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SFO to HNL only.

One caution: this is a thin sample. 365 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.

What to do with this

Booking UA 1175

For a booking, UA 1175 has one of the better records a US domestic flight can show: 91.7% on time and 0.55% cancelled. That is a base rate, not a promise about any single day.
