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

Alaska on HNL to PDX lands a B, level with the national rate of 77.6%. Roughly one flight in five 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 452 flights, with a median arrival 1 minute early.

The US average over the same twelve months is 77.6%, so there is little to separate Alaska on HNL to PDX from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Every carrier on HNL to PDX, 920 flights

These figures cover 452 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 HNL to PDX

Alaska flew 452 of the 920 flights on HNL to PDX, about 49% of it. Its 77.8% on time is about level with the route as a whole at 76.6%. Ranked by on-time rate it is first of two carriers on the route, where the range runs from Alaska at 77.8% to Hawaiian at 75.4%.

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 19 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

5am–8am38 flights81.6%
8am–11am49 flights87.8%
11am–2pm185 flights69.3%
2pm–5pm—
5pm–8pm—
8pm–5am180 flights82.7%

Scale runs 60% to 95%. Rows with fewer than 30 flights show a dash.

The weak window here is the middle of the day, not the evening: 11am–2pm runs 69.3% on time against 87.8% for 8am–11am. That shape usually means a departure bank rather than an accumulating delay, so the recovery later in the afternoon is real rather than noise. The 11am–2pm window is the busiest, with 185 flights scheduled in it.

Across the year

Alaska on HNL to PDX through the year

Jan–Mar 2026223 flights73.4%
Apr–Jun 2026229 flights81.9%

Scale runs 65% to 85%. 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 77.8% on time across 452 flights.

Split by quarter, Alaska on HNL to PDX logged 223 flights in Jan–Mar 2026 and 229 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 77.8% annual figure is the one to use.

Across the week, Saturday is the strongest day at 83.6% on time and Friday the weakest at 72.4%. 11 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 71% of the 6,542 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, 71%, 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 4,658 of the 6,542 delay minutes reported here. The split is drawn from 6,542 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

5.6% 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 2,603 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 65.5% on time across 453 flights, 12 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 12 points of difference.

One caution: this is a thin sample. 452 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 HNL to PDX

Put together: treat all of this as provisional. 452 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 77.8% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 445 completed flights over 12 months sit behind that.
