Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Hawaiian Airlines.

Hawaiian on SEA to OGG lands a B+, about a point worse than the national rate of 77.6%. About one flight in four arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 184 flights. The strongest carrier on the route with a full sample, Delta Air Lines, flew 365 at 87.7% on time.

The US average over the same twelve months is 77.6%, so there is little to separate Hawaiian on SEA 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 SEA to OGG, 1,809 flights

These figures cover 184 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

Hawaiian against every carrier on SEA to OGG

Hawaiian flew 184 of the 1,809 flights on SEA to OGG, about 10% of it. Its 76.4% on time is 3 points worse than the route as a whole, which runs 79.0%. Ranked by on-time rate it is last of three carriers on the route, where the range runs from Delta at 87.7% to Hawaiian at 76.4%.

The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 87.7% of the time; Alaska Airlines manages 76.9%. Sample sizes sit next to every figure, because a two-point gap across 1,260 flights means less than a ten-point one.

On-time performance by carrier on SEA to OGG
Airline	Flights	On time	Avg delay	Cancelled	Grade
Delta Air Lines	365	87.7%	41 min	1.10%	A
Alaska Airlines	1,260	76.9%	47 min	0.63%	B+
Hawaiian Airlines (this page)thin sample	184	76.4%	63 min	0.00%	B+

Delta leads Alaska by 11 points. Real, but small enough that a better departure time on the weaker carrier can outweigh it.

Departure window

When Hawaiian 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 184 flights.

There are not enough flights in each departure window to split Hawaiian's SEA to OGG record by time of day without the percentages moving on noise. The headline rate of 76.4% is the reliable figure here.

Across the year

Hawaiian on SEA to OGG through the year

Jul–Sep 202592 flights85.6%
Oct–Dec 202592 flights67.4%

Scale runs 60% to 90%. 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 76.4% on time across 184 flights.

Split by quarter, Hawaiian on SEA to OGG logged 92 flights in Jul–Sep 2025 and 92 flights in Oct–Dec 2025. Fewer than three of those quarters carried the 30 completed flights this site needs before printing a rate, so the 76.4% annual figure is the one to use.

Delay causes

Why Hawaiian runs late on this route

One category carries most of the weight here. Carrier accounts for 76% of the 2,698 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.

The largest share of delay minutes, 76%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 2,053 of the 2,698 delay minutes reported here. The split is drawn from 2,698 reported delay minutes.

Cancellations are rare at 0.00%, below the national 1.81% and low enough to earn the plus on the grade. Almost no flights are called off; the risk here is arriving late, not not arriving.

Connections and stage length

What a delay here costs

6.0% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.

At 2,639 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.

The return leg is a different operation and performs like one: it runs 59.6% on time across 184 flights, 17 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 17 points of difference.

One caution: this is a thin sample. 184 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 Hawaiian on SEA to OGG

Put together: treat all of this as provisional. 184 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 76.4% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 182 completed flights over 12 months sit behind that.
