Every carrier on PSP to PDX, 737 flights

These figures cover 229 flights between July 2025 and June 2026. The median arrival is 20 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.

Departure window

When SkyWest 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 229 flights.

There are not enough flights in each departure window to split SkyWest's PSP to PDX record by time of day without the percentages moving on noise. The headline rate of 96.0% is the reliable figure here.

Across the year

SkyWest on PSP to PDX through the year

Jul–Sep 202592 flights97.8%
Oct–Dec 202558 flights96.6%
Jan–Mar 202610 flights—
Apr–Jun 202669 flights95.7%

Scale runs 85% to 100%. 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 96.0% on time across 229 flights.

Quarter by quarter SkyWest on PSP to PDX held fairly steady: 97.8% in Jul–Sep 2025, 96.6% in Oct–Dec 2025 and 95.7% in Apr–Jun 2026. A spread of 2 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Across the week, Monday is the strongest day at 100.0% on time and Saturday the weakest at 90.9%. 9 points is a smaller lever than departure hour, but it is free.

Delay causes

Why SkyWest runs late on this route

One category carries most of the weight here. National Airspace System accounts for 70% of the 907 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.

National Airspace System
70%
Carrier
27%
Late-arriving aircraft
4%

70% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 632 minutes out of 907, against a national NAS share of 21%. The split is drawn from 907 reported delay minutes.

Cancellations sit at 1.75% 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 1.8% 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 74.2% on time across 230 flights, 22 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 22 points of difference.

One caution: this is a thin sample. 229 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 SkyWest on PSP to PDX

Put together: treat all of this as provisional. 229 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 96.0% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 225 completed flights over 12 months sit behind that.
