These figures cover 365 flights between September 2025 and August 2026. The median arrival is 10 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.

| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 27 August 2026 | 6 hours 37 minutes | Carrier |
| 26 August 2026 | 6 hours 16 minutes | Carrier |

Delay causes
Why UA 1175 runs late
Carrier accounts for 75% of the 2,620 delay minutes carriers reported here, and the remaining four split what is left.
- 75%Carrier
- 17%National Airspace System
- 8%Late-arriving aircraft
The largest share of delay minutes, 75%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,965 of the 2,620 delay minutes reported here. The split is drawn from 2,620 delay minutes reported on UA 1175.
Cancellations are rare at 0.27%, below the national 1.89% 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 3.6% land an hour or more behind schedule, against 8.3% 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: 90.7% on time and 0.27% cancelled. That is a base rate, not a promise about any single day.
