These figures cover 350 flights between September 2025 and August 2026. The median arrival is 14 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 KOA to LAX
American flew 350 of the 1,601 flights on KOA to LAX, about 22% of it. Its 83.2% on time is 3 points worse than the route as a whole, which runs 86.5%. Ranked by on-time rate it is number three of five carriers on the route, where the range runs from United at 91.5% to Alaska at 79.5%. 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 91.5% of the time; Alaska Airlines manages 79.5%. Sample sizes sit next to every figure, because a two-point gap across 374 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| United Airlines | 489 | 91.5% | 77 min | 1.02% | A |

Delta Air Lines cancels 3.0% of what it schedules here, the highest in the table. A cancelled flight never appears in an on-time rate, so read that column alongside the punctuality one rather than after 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 19 points, against 12 points between the best and worst carrier.
- 5am–8am—
- 8am–11am—
- 11am–2pm44 flights74.4%
- 2pm–5pm215 flights80.8%
- 5pm–8pm—
- 8pm–5am91 flights93.3%
Scale runs 65% to 100%. Rows with fewer than 30 flights show a dash.
The weak window here is the middle of the day, not the evening: 11am–2pm runs 74.4% on time against 93.3% for 8pm–5am. That shape usually means a departure bank rather than an accumulating delay, so the recovery later in the afternoon is real rather than noise. The 2pm–5pm window is the busiest, with 215 flights scheduled in it.

Arrival by arrival
How late American on KOA to LAX runs when it is late
American on KOA to LAX often beats the schedule: 161 of 346 completed flights, 47%, arrived 15 minutes or more early. Most of the lateness is short. 30 of the 58 late arrivals were under half an hour behind, and 21 reached an hour or more.

Share of 346 completed flights by arrival against schedule.
13 of 52 late departures made up the time and arrived on time, 25% of them. In the other direction, 19 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 American on KOA to LAX
The latest arrival of the period was on 23 September 2025, 20 hours 17 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 23 September 2025 | 20 hours 17 minutes | Carrier |
| 13 March 2026 | 18 hours 42 minutes | Extreme weather |
| 16 January 2026 | 16 hours 4 minutes | Carrier |
| 16 August 2026 | 6 hours 16 minutes | Late-arriving aircraft |
| 8 September 2025 | 3 hours 23 minutes | Carrier |
Delay causes
Why American runs late on this route
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 6,737 reported delay minutes.
- 42%Carrier
- 34%Late-arriving aircraft
- 16%Extreme weather
- 8%National Airspace System
Extreme weather accounts for 16% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the monthly strip above is the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.7 times the usual weather exposure. The split is drawn from 6,737 reported delay minutes.
34% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 6,737 reported delay minutes here, that single category outweighs weather by 2 to one.
Cancellations sit at 1.14% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and stage length
What a delay here costs
6.1% 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 close to two hours, 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 74.9% on time across 350 flights, 8 points below 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 KOA to LAX
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 83.2% 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.
