Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Alaska Airlines.
Alaska on LAX to KOA lands a B, about a point worse than the national rate of 77.6%. About one flight in four arrives 15 minutes late or worse, and those flights are late by roughly 40 minutes on average. That is a workable record, not a spotless one. That rests on 374 flights. The strongest carrier on the route with a full sample, United Airlines, flew 494 at 89.1% on time.
The US average over the same twelve months is 77.6%, so there is little to separate Alaska on LAX to KOA from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Every carrier on LAX to KOA, 1,606 flights
These figures cover 374 flights between July 2025 and June 2026. On-time means an arrival less than 15 minutes after the scheduled gate time, the same threshold the Department of Transportation uses in its own reports. Cancelled and diverted flights are excluded from the on-time rate and counted separately, which is why the cancellation column matters on its own.
Carrier by carrier
Alaska against every carrier on LAX to KOA
Alaska flew 374 of the 1,606 flights on LAX to KOA, about 23% of it. Its 76.4% on time is 5 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 95.7% to Alaska at 76.4%. Two 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 89.1% of the time; Delta Air Lines manages 81.1%. Sample sizes sit next to every figure, because a two-point gap across 365 flights means less than a ten-point one.

United leads Delta by 8 points. Real, but small enough that a better departure time on the weaker carrier can outweigh it.

Alaska flight numbers on LAX to KOA
Departure window
When Alaska runs best on this route
Departure time is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 374 flights.
There are not enough flights in each departure window to split Alaska's LAX to KOA record by time of day without the percentages moving on noise. The headline rate of 76.4% is the reliable figure here.
Across the year
Alaska on LAX to KOA through the year
July is the worst month at 45.2% on time, 52 points below May, the best at 96.8%. Summer afternoon convection and peak-season schedules land on the same weeks every year, so this is a pattern you can book around rather than a run of bad luck. April was the busiest month here, with 36 flights.
Across the week, Wednesday is the strongest day at 80.4% on time and Saturday the weakest at 70.9%. 10 points is a smaller lever than departure hour, but it is free.
Delay causes
Why Alaska runs late on this route
One category carries most of the weight here. National Airspace System accounts for 63% of the 3,663 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.

- 2%Extreme weather

63% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 2,299 minutes out of 3,663, against a national NAS share of 21%. The split is drawn from 3,663 reported delay minutes.
Cancellations sit at 1.07% against a national 1.81%, which is ordinary. Diversions add another 0.53%.
Connections and stage length
What a delay here costs
Badly late arrivals are rare here: only 3.5% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
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 runs 78.4% on time across 374 flights, within 2 points of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
One caution: this is a thin sample. 374 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 Alaska on LAX to KOA
Put together: treat all of this as provisional. 374 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 76.4% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 368 completed flights over 12 months sit behind that.
