Historical statistics for July 2025 to June 2026, not live status. For today’s UA 1157, check with United Airlines.

UA 1157 lands a B+, 6 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by an hour and a half on average. That is a workable record, not a spotless one. That rests on 365 flights, with a median arrival 8 minutes early.

Set against the rest of the country, UA 1157's record is 6 points better than the US average of 77.6%. That gap is worth roughly 61 fewer late arrivals for every thousand flights.

These figures cover 365 flights between July 2025 and June 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.

Schedule

When UA 1157 flies

UA 1157 flies HNL to LAX without a single fixed slot. Its most common scheduled departure was 12:35, used on 63 of 365 flights, with 13:00 (61 flights) and 12:45 (56 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 12:35 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and UA 1157 runs 5 points better at 83.7%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

UA 1157 quarter by quarter

Quarter by quarter UA 1157 held fairly steady: 89.1% in Jul–Sep 2025, 81.5% in Oct–Dec 2025, 79.8% in Jan–Mar 2026 and 84.4% in Apr–Jun 2026. A spread of 9 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202592 flights89.1%
Oct–Dec 202592 flights81.5%
Jan–Mar 202690 flights79.8%
Apr–Jun 202691 flights84.4%

Scale runs 70% to 95%. Rows with fewer than 30 flights show a dash.

By weekday, UA 1157 ranged from 78.8% on Friday to 88.5% on Thursday. With about 52 flights behind each day, a spread of 10 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why UA 1157 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 51% of the 5,031 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.

Late-arriving aircraft
51%
Carrier
29%
National Airspace System
21%

51% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 5,031 reported delay minutes here, that single category outweighs weather by 51 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 5,031 delay minutes reported on UA 1157.

Cancellations are rare at 0.27%, 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

7.7% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last an hour and a half, 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
