These figures cover 364 flights between September 2025 and August 2026. The median arrival is 8 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.

The latest arrival of the period was on 20 November 2025, 13 hours 17 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 20 November 2025 | 13 hours 17 minutes | Late-arriving aircraft |
| 3 October 2025 | 8 hours 14 minutes | Late-arriving aircraft |
| 23 August 2026 | 7 hours 17 minutes | Late-arriving aircraft |
| 23 July 2026 | 2 hours 10 minutes | Carrier |

Delay causes
Why UA 1158 runs late
Late-arriving aircraft accounts for 44% of the 3,185 delay minutes carriers reported here, and the remaining four split what is left.
- 44%Late-arriving aircraft
- 41%Carrier
- 15%National Airspace System
44% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,185 reported delay minutes here, that single category outweighs weather by 44 to one. The split is drawn from 3,185 delay minutes reported on UA 1158.
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 2.5% 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 2,556 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.
Every one of the 364 flights under UA 1158 in the data flew LAX to HNL. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 364 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 1158
For a booking, UA 1158 has one of the better records a US domestic flight can show: 87.8% on time and 0.27% cancelled. That is a base rate, not a promise about any single day.
