Every carrier on KOA to OGG, 1,460 flights

These figures cover 729 flights between September 2025 and August 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 KOA to OGG

Alaska flew 729 of the 1,460 flights on KOA to OGG, about 50% of it. Its 82.2% on time is 5 points worse than the route as a whole, which runs 86.9%. Ranked by on-time rate it is last of three carriers on the route, where the range runs from Southwest at 91.8% to Alaska at 82.2%.

The two carriers here are closely matched: half a point separate the best from the worst. At that spread, schedule and price are better tie-breakers than reliability. Sample sizes are shown so you can see which rows are worth weighing.

Departure window

When Alaska runs best on this route

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 17 points, against half a point between the best and worst carrier.

5am–8am—
8am–11am243 flights91.7%
11am–2pm335 flights74.9%
2pm–5pm151 flights83.4%
5pm–8pm—
8pm–5am—

Scale runs 65% to 95%. 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 74.9% on time against 91.7% for 8am–11am. 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 11am–2pm window is the busiest, with 335 flights scheduled in it.

Delay causes

Why Alaska runs late on this route

Late-arriving aircraft accounts for 63% of the 4,916 delay minutes carriers reported here, and the remaining four split what is left.

63% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,916 reported delay minutes here, that single category outweighs weather by 11 to one. The split is drawn from 4,916 reported delay minutes.

The practical consequence: the 8am–11am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 91.7% on time here.

Cancellations are rare at 0.41%, 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

Badly late arrivals are rare here: only 2.8% 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 84 miles this is a short hop, and stage length matters more than it looks. A flight this short spends under two hours in the air, which leaves almost nothing to claw back a late pushback with. Delay here is decided on the ground, in the turn, which is why the 8am–11am window matters as much as it does.

The return leg is a different operation and performs like one: it runs 74.9% on time across 729 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. 729 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 KOA to OGG

Put together: treat all of this as provisional. 729 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 82.2% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 726 completed flights over 12 months sit behind that.
