This route earns a B. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 7 points better than the national rate of 77.3%. When something does go wrong the average delay runs roughly 45 minutes. That rests on 10,001 OGG to HNL flights, of which Southwest Airlines flew 2,861 at 93.9% on time.
Best time to fly OGG to HNL: a 5am–8am departure, ideally on a Tuesday. Flights in that window arrived on time 94.2% of the time and Tuesday flights 89.1%, against 84.1% for the route overall.

These figures cover 10,000 flights between September 2025 and August 2026. The median arrival is 2 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Carrier by carrier
Which airline is most reliable on OGG to HNL
The choice of carrier is not cosmetic here. Southwest Airlines arrives on time 93.9% of the time; Alaska Airlines manages 77.9%. Sample sizes sit next to every figure, because a two-point gap across 4,653 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Southwest Airlines | 2,861 | 93.9% | 50 min | 0.59% | A+ |
| Hawaiian Airlines | 2,487 | 84.1% | 41 min | 0.88% | B+ |
| Alaska Airlines | 4,653 | 77.9% | 43 min | 1.85% | B |
The spread between Southwest and Alaska is 16 points, wide enough that it should decide the booking. On a hundred trips that is 16 more arrivals inside the on-time window.

Best ways to make this trip
The most reliable ways to fly Kahului to Honolulu
Every airline on this route, ranked by how often a scheduled flight actually operated and arrived on time, with its best departure time and most punctual flight number. No nearby airport pair beat these.

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.
Departure window
The best time of day to leave
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 21 points, against 16 points between the best and worst carrier.

Book the early departure. Flights leaving between 5am–8am arrive on time 94.2% of the time, against 73.4% for the overnight window. That is 21 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8am–11am window is the busiest, with 2,278 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 20 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.
September is the best month on the calendar at 93.3% on time. Shoulder season thins the schedule and takes the summer weather with it, and the operation gets its margin back. January was the busiest month here, with 898 flights.
Across the week, Tuesday is the strongest day at 89.1% on time and Friday the weakest at 80.5%, a spread of 9 points.
Delay causes
Why this route gets delayed
Late-arriving aircraft accounts for 55% of the 68,000 delay minutes carriers reported here, and the remaining four split what is left.
- 55%Late-arriving aircraft
- 32%Carrier
- 8%National Airspace System
- 5%Extreme weather
- 0%Security
55% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 68,000 reported delay minutes here, that single category outweighs weather by 12 to one. The split is drawn from 68,085 reported delay minutes.
The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 94.2% on time here.
Cancellations sit at 1.25% against a national 1.89%, which is ordinary. Diversions add another 0.04%.
Connections and stage length
What a delay here actually costs
Badly late arrivals are rare here: only 2.7% 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 101 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 5am–8am window matters as much as it does.
The return leg runs 84.1% on time across 9,998 flights, within half a point of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
The sample behind these figures is 10,001 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 93.3% on time and March 73.8%, a swing of 20 points. If the dates move at all, move them out of March before you think about anything else. 9,872 completed flights over 12 months sit behind that.
Common questions
OGG to HNL questions
How often is OGG to HNL delayed?
About one flight in six arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 15.9% of the 10,001 flights in this analysis, against 22.7% nationally. Delayed flights are late by roughly 45 minutes on average.
Which airline is most reliable on OGG to HNL?
Southwest Airlines leads at 93.9% on time across 2,861 flights. Alaska Airlines is at the other end on 77.9%, a gap of 16 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 HNL?
The 5am–8am departure window is the strongest at 94.2% on time. The 8pm–5am window is the weakest at 73.4%, 21 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 March delays on OGG to HNL?
March is the weakest month at 73.8% on time, compared with 93.3% in September. Across the year that is 20 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
