Historical statistics for July 2025 to June 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, 3 points worse than the national rate of 77.6%. The late ones land about 45 minutes behind schedule. That rests on 543 flights. The strongest carrier on the route with a full sample, Southwest Airlines, flew 365 at 86.0% on time.

The US average over the same twelve months is 77.6%, 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 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 OGG to KOA

Alaska flew 543 of the 1,460 flights on OGG to KOA, about 37% of it. Its 74.5% on time is 6 points worse than the route as a whole, which runs 80.3%. Ranked by on-time rate it is last of three carriers on the route, where the range runs from Southwest at 86.0% to Alaska at 74.5%.

The two carriers here are closely matched: 4 points 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.

No carrier stands out. Southwest tops the table at 86.0%, 4 points 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 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 543 flights.

  • 5am–8am
  • 8am–11am
  • 11am–2pm307 flights71.2%
  • 2pm–5pm236 flights78.7%
  • 5pm–8pm
  • 8pm–5am

Scale runs 65% to 85%. 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 71.2% on time against 78.7% for 2pm–5pm. 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 307 flights scheduled in it.

Across the year

Alaska on OGG to KOA through the year

  • Jan–Mar 2026270 flights69.8%
  • Apr–Jun 2026273 flights79.1%

Scale runs 60% 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 74.5% on time across 543 flights.

Split by quarter, Alaska on OGG to KOA 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 74.5% annual figure is the one to use.

Across the week, Wednesday is the strongest day at 88.0% on time and Thursday the weakest at 62.8%. 25 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 65% of the 6,208 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.

  • Late-arriving aircraft
    65%
  • Carrier
    25%
  • National Airspace System
    5%
  • Extreme weather
    4%

65% 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 6,208 reported delay minutes here, that single category outweighs weather by 15 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 6,208 reported delay minutes.

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 4.6% 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 2pm–5pm window matters as much as it does.

The return leg is a different operation and performs like one: it runs 81.4% on time across 543 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. 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 OGG to KOA

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 74.5% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 541 completed flights over 12 months sit behind that.
