Every carrier on LAX to LIH, 1,605 flights

These figures cover 272 flights between September 2025 and August 2026. The median arrival is 3 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

Alaska against every carrier on LAX to LIH

Alaska flew 272 of the 1,605 flights on LAX to LIH, about 17% of it. Its 76.5% on time is 6 points worse than the route as a whole, which runs 82.9%. Ranked by on-time rate it is number five of six carriers on the route, where the range runs from Southwest at 100.0% to American at 75.1%. 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 94.7% of the time; American Airlines manages 75.1%. Sample sizes sit next to every figure, because a two-point gap across 446 flights means less than a ten-point one.

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 272 flights.

There are not enough flights in each departure window to split Alaska's LAX to LIH record by time of day without the percentages moving on noise. The headline rate of 76.5% is the reliable figure here.

Share of 268 completed flights by arrival against schedule.

19 of 67 late departures made up the time and arrived on time, 28% of them. In the other direction, 15 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 LIH.

Delay causes

Why Alaska runs late on this route

Carrier accounts for 69% of the 2,882 delay minutes carriers reported here, and the remaining four split what is left.

National Airspace System

Late-arriving aircraft

The largest share of delay minutes, 69%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,990 of the 2,882 delay minutes reported here. The split is drawn from 2,882 reported delay minutes.

Cancellations sit at 1.10% against a national 1.89%, which is ordinary. Diversions add another 0.37%.

Connections and stage length

What a delay here costs

Badly late arrivals are rare here: only 3.4% land an hour or more behind schedule, against 8.3% 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 2,615 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 69.9% on time across 272 flights, 7 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 7 points of difference.

One caution: this is a thin sample. 272 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 LIH

Put together: treat all of this as provisional. 272 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 76.5% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 268 completed flights over 12 months sit behind that.
