These figures cover 365 flights between September 2025 and August 2026. The median arrival is 6 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.

Share of 363 completed flights by arrival against schedule.
7 of 48 late departures made up the time and arrived on time, 15% of them. In the other direction, 30 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at LAX.
The worst days
Worst days for UA 1157
The latest arrival of the period was on 17 October 2025, 5 hours 13 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on five of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 17 October 2025 | 5 hours 13 minutes | Late-arriving aircraft |
| 2 April 2026 | 4 hours 55 minutes | Late-arriving aircraft |
| 28 October 2025 | 3 hours 54 minutes | Late-arriving aircraft |

Delay causes
Why UA 1157 runs late
Late-arriving aircraft accounts for 54% of the 5,220 delay minutes carriers reported here, and the remaining four split what is left.
- 54%Late-arriving aircraft
- 23%Carrier
- 22%National Airspace System
- 0%Extreme weather
54% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 5,220 reported delay minutes here, that single category outweighs weather by 54 to one. The split is drawn from 5,220 delay minutes reported on UA 1157.
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
7.7% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, which a normal layover absorbs.
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.
The same number turns up on one other city pair in the data, including LAX to CLE (27), but none flew often enough under UA 1157 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to HNL to LAX 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 1157
