Alaska on PSP to PDX earns an A. Nearly every flight arrives inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 16 points better than the national rate of 77.6%. When something does go wrong the average delay runs an hour and a half. That rests on 508 flights, with a median arrival 15 minutes early.
Set against the rest of the country, Alaska's PSP to PDX record is 16 points better than the US average of 77.6%. That gap is worth roughly 162 fewer late arrivals for every thousand flights.

Every carrier on PSP to PDX, 737 flights
These figures cover 508 flights between July 2025 and June 2026. The median arrival is 15 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
Alaska against every carrier on PSP to PDX
Alaska flew 508 of the 737 flights on PSP to PDX, most of the route. Its 93.8% on time is about level with the route as a whole at 94.5%. Ranked by on-time rate it is last of two carriers on the route, where the range runs from SkyWest at 96.0% to Alaska at 93.8%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
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 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 508 flights.
- 5am–8am145 flights93.7%
- 8am–11am38 flights97.1%
- 11am–2pm119 flights93.2%
- 2pm–5pm81 flights93.8%
- 5pm–8pm118 flights93.2%
- 8pm–5am7 flights—
Scale runs 85% to 100%. Rows with fewer than 30 flights show a dash.
The time of day barely matters here. The 8am–11am window tops the set at 97.1% and 5pm–8pm sits at 93.2%, 4 points apart across 508 flights. Pick the departure that suits the trip: whatever is going wrong here is not accumulating over the course of the day. The 5am–8am window is the busiest, with 145 flights scheduled in it.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 93.8% on time across 508 flights.
Quarter by quarter Alaska on PSP to PDX held fairly steady: 92.6% in Oct–Dec 2025, 92.3% in Jan–Mar 2026 and 99.0% in Apr–Jun 2026. A spread of 7 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.
Across the week, Tuesday is the strongest day at 97.1% on time and Saturday the weakest at 89.2%. 8 points is a smaller lever than departure hour, but it is free.
Delay causes
Why Alaska runs late on this route
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 2,862 reported delay minutes.
- 33%Late-arriving aircraft
- 30%Carrier
- 21%National Airspace System
- 16%Extreme weather
- 0%Security
Extreme weather accounts for 16% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the monthly strip above is the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.5 times the usual weather exposure. The split is drawn from 2,862 reported delay minutes.
The practical consequence: the 8am–11am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 97.1% on time here.
Cancellations sit at 1.77% 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 2.8% 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.
The 873 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
The return leg is a different operation and performs like one: it runs 88.1% on time across 508 flights, 6 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 6 points of difference.
One caution: this is a thin sample. 508 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 PSP to PDX
Put together: treat all of this as provisional. 508 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 93.8% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 499 completed flights over 12 months sit behind that.
