Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Alaska Airlines.
Alaska on KOA to OGG lands a B+, 4 points better than the national rate of 77.6%. About one flight in five 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 543 flights. The strongest carrier on the route with a full sample, Hawaiian Airlines, flew 552 at 90.0% on time.
The US average over the same twelve months is 77.6%, so there is little to separate Alaska on KOA to OGG from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Every carrier on KOA to OGG, 1,460 flights
These figures cover 543 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 KOA to OGG
Alaska flew 543 of the 1,460 flights on KOA to OGG, about 37% of it. Its 81.4% on time is 5 points worse than the route as a whole, which runs 86.8%. Ranked by on-time rate it is last of three carriers on the route, where the range runs from Hawaiian at 90.0% to Alaska at 81.4%.
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.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Hawaiian Airlines | 552 | 90.0% | 40 min | 0.36% | A+ |
| Southwest Airlines | 365 | 89.9% | 63 min | 0.00% | A+ |
| Alaska Airlines (this page) | 543 | 81.4% | 38 min | 0.18% | B+ |
No carrier stands out. Hawaiian tops the table at 90.0%, half a point clear of the bottom, which is inside the range this kind of sample moves year to year.
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. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am—
- 8am–11am181 flights91.1%
- 11am–2pm273 flights74.0%
- 2pm–5pm89 flights84.3%
- 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 74.0% on time against 91.1% 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 273 flights scheduled in it.
Across the year
Alaska on KOA to OGG through the year
- Jan–Mar 2026270 flights81.5%
- Apr–Jun 2026273 flights81.2%
Scale runs 75% to 85%. Rows with fewer than 30 flights show a dash.
Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 81.4% on time across 543 flights.
Split by quarter, Alaska on KOA to OGG logged 270 flights in Jan–Mar 2026 and 273 flights in Apr–Jun 2026. Fewer than three of those quarters carried the 30 completed flights this site needs before printing a rate, so the 81.4% annual figure is the one to use.
Across the week, Monday is the strongest day at 87.2% on time and Friday the weakest at 72.7%. 15 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. Late-arriving aircraft accounts for 61% of the 3,788 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.
- 61%Late-arriving aircraft
- 26%Carrier
- 7%Extreme weather
- 4%National Airspace System
- 1%Security
61% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 3,788 reported delay minutes here, that single category outweighs weather by 8 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 3,788 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 91.1% on time here.
Cancellations are rare at 0.18%, below the national 1.81% 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 3.0% 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 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 74.5% on time across 543 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. 543 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. 543 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 81.4% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 542 completed flights over 12 months sit behind that.
