Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with Alaska Airlines.
Alaska on OGG to KOA sits in the middle of the pack with a C+. Close to three flights in four arrive on time by the DOT's definition, 2 points worse than the national rate of 77.3%. The late ones land roughly 45 minutes behind schedule. That rests on 729 flights. The strongest carrier on the route with a full sample, Southwest Airlines, flew 365 at 87.4% on time.
The US average over the same twelve months is 77.3%, so there is little to separate Alaska on OGG 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 OGG to KOA, 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 OGG to KOA

Departure window
When Alaska runs best on this route

Share of 725 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 153 departures that left 15 minutes late or more, only 12 made it up before arrival. In the other direction, 41 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 KOA.
The worst days
Worst days for Alaska on OGG to KOA
The latest arrival of the period was on 13 March 2026, 6 hours 54 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). On three of the five worst days the largest share was filed as a late-arriving aircraft.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 13 March 2026 | 6 hours 54 minutes | Carrier |
| 19 August 2026 | 4 hours 52 minutes | Carrier |
| 30 July 2026 | 4 hours 9 minutes | Late-arriving aircraft |
| 14 March 2026 | 3 hours 46 minutes | Late-arriving aircraft |
| 15 May 2026 | 3 hours 42 minutes | Late-arriving aircraft |
Delay causes
Why Alaska runs late on this route
Late-arriving aircraft accounts for 65% of the 8,588 delay minutes carriers reported here, and the remaining four split what is left.
- 65%Late-arriving aircraft
- 26%Carrier
- 7%National Airspace System
- 3%Extreme weather
65% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 8,588 reported delay minutes here, that single category outweighs weather by 21 to one. The split is drawn from 8,588 reported delay minutes.
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 4.8% 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 2pm–5pm window matters as much as it does.
The return leg is a different operation and performs like one: it runs 82.2% on time across 729 flights, 7 points above 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 OGG to KOA
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 74.9% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 725 completed flights over 12 months sit behind that.
