AA 143 lands a B+, 2 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by about 50 minutes on average. That is a workable record, not a spotless one. That rests on 365 flights, with a median arrival 10 minutes early.

These figures cover 365 flights between July 2025 and June 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.

Schedule

When AA 143 flies

AA 143 flies LAX to HNL without a single fixed slot. Its most common scheduled departure was 15:48, used on 44 of 365 flights, with 16:17 (37 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 15:48 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and AA 143 runs 8 points better at 79.9%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

AA 143 quarter by quarter

Quarter by quarter AA 143 held fairly steady: 81.5% in Jul–Sep 2025, 80.2% in Oct–Dec 2025, 82.2% in Jan–Mar 2026 and 75.8% in Apr–Jun 2026. A spread of 6 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202592 flights81.5%
Oct–Dec 202592 flights80.2%
Jan–Mar 202690 flights82.2%
Apr–Jun 202691 flights75.8%

Scale runs 65% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, AA 143 did best on Wednesday at 88.5% on time and worst on Sunday at 67.3%. Each day rests on about 52 flights, so a gap of 21 points is worth noticing but could still narrow in another year.

Delay causes

Why AA 143 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 43% of the 3,646 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.

37%

43% 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 3,646 reported delay minutes here, that single category outweighs weather by 43 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 3,646 delay minutes reported on AA 143.

Cancellations are rare at 0.00%, below the national 1.81% and low enough to earn the plus on the grade. Almost no flights are called off; the risk here is arriving late, not not arriving.

Connections and routes

What a delay on this flight costs

5.5% 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 about 50 minutes, 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.

Every one of the 365 flights under AA 143 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. 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 AA 143

For a booking, read AA 143 as 79.9% on time with 0.00% cancelled over 365 flights. Those are rates from the past twelve months, not a forecast for any particular day.
