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

Hawaiian on OGG to SEA draws a D+. Roughly one flight in two arrives at least 15 minutes late, and the typical late arrival is roughly 40 minutes behind schedule. Build slack into anything you connect to. That rests on 184 flights. The strongest carrier on the route with a full sample, Delta Air Lines, flew 365 at 95.3% on time.

The national on-time rate over the same period is 77.6%, so Hawaiian on OGG to SEA runs 18 points behind the country as a whole. Across a thousand flights that is about 180 extra late arrivals.

These figures cover 184 flights between July 2025 and June 2026. Beyond the headline rate, 9.3% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Carrier by carrier

Hawaiian against every carrier on OGG to SEA

Hawaiian flew 184 of the 1,809 flights on OGG to SEA, about 10% of it. Its 59.6% on time is 20 points worse than the route as a whole, which runs 79.3%. Ranked by on-time rate it is last of three carriers on the route, where the range runs from Delta at 95.3% to Hawaiian at 59.6%.

The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 95.3% of the time; Alaska Airlines manages 77.6%. 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 OGG to SEA
Airline	Flights	On time	Avg delay	Cancelled	Grade
Delta Air Lines	365	95.3%	94 min	1.92%	A
Alaska Airlines	1,260	77.6%	56 min	1.90%	B
Hawaiian Airlines (this page)thin sample	184	59.6%	42 min	0.54%	D+

The spread between Delta and Alaska is 18 points, wide enough that it should decide the booking. On a hundred trips that is 18 more arrivals inside the on-time window.

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.

Across the year

Hawaiian on OGG to SEA through the year

Jul–Sep 202592 flights67.4%
Oct–Dec 202592 flights51.6%

Scale runs 45% to 75%. 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 59.6% on time across 184 flights.

Split by quarter, Hawaiian on OGG to SEA 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 59.6% 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 78% of the 3,105 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, 78%, 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 2,418 of the 3,105 delay minutes reported here. The split is drawn from 3,105 reported delay minutes.

Cancellations are rare at 0.54%, 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

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 9.3% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.

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 76.4% on time across 184 flights, 17 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 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 OGG to SEA

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 59.6% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 183 completed flights over 12 months sit behind that.
