Every carrier on PDX to HNL, 917 flights

These figures cover 453 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 PDX to HNL

Alaska flew 453 of the 917 flights on PDX to HNL, about 49% of it. Its 65.5% on time is 3 points better than the route as a whole, which runs 62.1%. Ranked by on-time rate it is first of two carriers on the route, where the range runs from Alaska at 65.5% to Hawaiian at 58.7%.

Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

Departure window

When Alaska runs best on this route

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 16 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

Scale runs 50% to 80%. Rows with fewer than 30 flights show a dash.

Book the early departure. Flights leaving between 5am–8am arrive on time 75.5% of the time, against 59.4% for the morning window. That is 16 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 213 flights scheduled in it.

Across the year

Alaska on PDX to HNL through the year

Jan–Mar 2026225 flights60.9%
Apr–Jun 2026228 flights69.9%

Scale runs 50% 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 65.5% on time across 453 flights.

Split by quarter, Alaska on PDX to HNL logged 225 flights in Jan–Mar 2026 and 228 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 65.5% annual figure is the one to use.

Across the week, Sunday is the strongest day at 72.1% on time and Friday the weakest at 54.5%. 18 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. Carrier accounts for 70% of the 7,154 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, 70%, 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 5,020 of the 7,154 delay minutes reported here. The split is drawn from 7,154 reported delay minutes.

Cancellations sit at 1.55% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and stage length

What a delay here costs

Badly late arrivals are rare here: only 4.7% 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 2,603 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 77.8% on time across 452 flights, 12 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 12 points of difference.

One caution: this is a thin sample. 453 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 PDX to HNL

Put together: treat all of this as provisional. 453 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 65.5% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 446 completed flights over 12 months sit behind that.
