These figures cover 1,460 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
Which airline is most reliable on OGG to KOA
The choice of carrier is not cosmetic here. Southwest Airlines arrives on time 87.4% of the time; Alaska Airlines manages 74.9%. Sample sizes sit next to every figure, because a two-point gap across 729 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Southwest Airlines | 365 | 87.4% | 44 min | 0.27% | A+ |
| Hawaiian Airlines | 366 | 81.6% | 40 min | 0.27% | B+ |
| Alaska Airlines | 729 | 74.9% | 47 min | 0.41% | C+ |
The spread between Southwest and Alaska is 13 points, wide enough that it should decide the booking. On a hundred trips that is 13 more arrivals inside the on-time window.

Success is the share of scheduled flights that operated and arrived less than 15 minutes late, so a cancelled flight counts against it. “(route)” means the best time comes from every carrier on the route rather than this airline alone.

Across the year
When delays peak on this route
This route's year swings by 17 points from best month to worst, which is wide. An annual average tells you very little about the week you are actually flying, so read the strip rather than the headline if your dates are fixed.
December is the weak month at 71.8% on time, against 89.2% in September. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. January was the busiest month here, with 124 flights.
Across the week, Tuesday is the strongest day at 86.1% on time and Saturday the weakest at 75.0%, a spread of 11 points.
Delay causes
Why this route gets delayed
Late-arriving aircraft accounts for 65% of the 13,000 delay minutes carriers reported here, and the remaining four split what is left.
- 65%Late-arriving aircraft
- 27%Carrier
- 6%National Airspace System
- 2%Extreme weather
65% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 13,000 reported delay minutes here, that single category outweighs weather by 33 to one. The split is drawn from 13,275 reported delay minutes.
Cancellations are rare at 0.34%, 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 actually costs
Badly late arrivals are rare here: only 3.9% 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 86.9% on time across 1,460 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.
The sample behind these figures is 1,460 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.

What to do with this
Booking this route
Put together: the calendar is the biggest lever here, not the carrier or the hour. September runs 89.2% on time and December 71.8%, a swing of 17 points. If the dates move at all, move them out of December before you think about anything else. 1,454 completed flights over 12 months sit behind that.
Common questions
OGG to KOA questions
How often is OGG to KOA delayed?
About one flight in five arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 20.3% of the 1,460 flights in this analysis, against 22.7% nationally. Delayed flights are late by about 45 minutes on average.
Which airline is most reliable on OGG to KOA?
Southwest Airlines leads at 87.4% on time across 365 flights. Alaska Airlines is at the other end on 74.9%, a gap of 13 points. Sample size matters as much as the percentage: a rate built from a few hundred flights moves around far more than one built from ten thousand.
What time of day has the fewest delays on OGG to KOA?
The 2pm–5pm departure window is the strongest at 81.0% on time. The 11am–2pm window is the weakest at 77.9%, 3 points behind. Later departures inherit delays from earlier flights the same aircraft has already flown, which is why the curve slopes the way it does.
How bad are December delays on OGG to KOA?
December is the weakest month at 71.8% on time, compared with 89.2% in September. Across the year that is 17 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
