These figures cover 350 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.

Carrier by carrier
American against every carrier on LAX to KOA
American flew 350 of the 1,601 flights on LAX to KOA, about 22% of it. Its 74.9% on time is 7 points worse than the route as a whole, which runs 81.8%. Ranked by on-time rate it is last of five carriers on the route, where the range runs from Southwest at 91.3% to American at 74.9%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The choice of carrier is not cosmetic here. United Airlines arrives on time 89.2% of the time; Alaska Airlines manages 78.7%. Sample sizes sit next to every figure, because a two-point gap across 374 flights means less than a ten-point one.

United leads Alaska by 11 points. Real, but small enough that a better departure time on the weaker carrier can outweigh it.

Departure window
When American runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 26 points, against 11 points between the best and worst carrier.

- 8am–11am46 flights55.6%
- 11am–2pm236 flights76.5%
- 2pm–5pm68 flights82.1%
- 5pm–8pm—
- 8pm–5am—
Scale runs 45% to 90%. Rows with fewer than 30 flights show a dash.
The best window here is not the first bank but the 2pm–5pm slot at 82.1% on time, ahead of 8am–11am at 55.6%. Where the curve peaks mid-day rather than at dawn, the constraint is usually congestion at one end rather than the aircraft's own rotation. The 11am–2pm window is the busiest, with 236 flights scheduled in it.

Share of 346 completed flights by arrival against schedule.
22 of 81 late departures made up the time and arrived on time, 27% of them. In the other direction, 28 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 KOA.

The latest arrival of the period was on 16 August 2026, 7 hours 20 minutes behind schedule; most of its delay minutes were filed as extreme weather. On four of the five worst days the largest share was filed as a late-arriving aircraft.

|---|---|---|
| 16 August 2026 | 7 hours 20 minutes | Extreme weather |
| 20 May 2026 | 4 hours 41 minutes | Late-arriving aircraft |

Delay causes
Why American runs late on this route
Late-arriving aircraft accounts for 48% of the 5,627 delay minutes carriers reported here, and the remaining four split what is left.
- 48%Late-arriving aircraft
- 24%Carrier
- 21%National Airspace System
- 7%Extreme weather
48% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 5,627 reported delay minutes here, that single category outweighs weather by 6 to one. The split is drawn from 5,627 reported delay minutes.
Cancellations are rare at 0.57%, 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 stage length
What a delay here costs
6.9% 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 about an hour, which a normal layover absorbs.
At 2,504 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 return leg is a different operation and performs like one: it runs 83.2% on time across 350 flights, 8 points above this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 8 points of difference.
One caution: this is a thin sample. 350 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 American on LAX to KOA
Put together: treat all of this as provisional. 350 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 74.9% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 346 completed flights over 12 months sit behind that.
