Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with SkyWest Airlines.
SkyWest on PSP to PHX lands a B, 3 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by close to two hours on average. That is a workable record, not a spotless one. That rests on 721 flights, with a median arrival 9 minutes early.
The US average over the same twelve months is 77.6%, so there is little to separate SkyWest on PSP to PHX from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Every carrier on PSP to PHX, 1,445 flights
These figures cover 721 flights between July 2025 and June 2026. Beyond the headline rate, 9.5% 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
SkyWest against every carrier on PSP to PHX
SkyWest flew 721 of the 1,445 flights on PSP to PHX, about 50% of it. Its 80.5% on time is about level with the route as a whole at 79.6%. Ranked by on-time rate it is number two of three carriers on the route, where the range runs from Envoy at 88.6% to American at 78.0%. 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 SkyWest runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 20 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–8am359 flights84.1%
- 8am–11am111 flights78.5%
- 11am–2pm38 flights92.1%
- 2pm–5pm113 flights74.1%
- 5pm–8pm100 flights72.2%
- 8pm–5am—
Scale runs 65% to 100%. Rows with fewer than 30 flights show a dash.
The best window here is not the first bank but the 11am–2pm slot at 92.1% on time, ahead of 5pm–8pm at 72.2%. Where the curve peaks mid-day rather than at dawn, the constraint is usually congestion at one end rather than the aircraft's own rotation. The 5am–8am window is the busiest, with 359 flights scheduled in it.
Across the year
SkyWest on PSP to PHX through the year
May is the best month on the calendar at 90.9% on time. Shoulder season thins the schedule and takes the summer weather with it, and the operation gets its margin back. November was the busiest month here, with 96 flights.
Across the week, Thursday is the strongest day at 86.8% on time and Monday the weakest at 74.3%. 13 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. Carrier accounts for 57% of the 16,000 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.
- 57%Carrier
- 22%Late-arriving aircraft
- 18%National Airspace System
- 3%Extreme weather
The largest share of delay minutes, 57%, 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 9,369 of the 16,000 delay minutes reported here. The split is drawn from 16,454 reported delay minutes.
Cancellations sit at 1.11% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
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. 9.5% 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 261 miles this is a short hop, and stage length matters more than it looks. A flight this short spends under two hours in the air, which leaves almost nothing to claw back a late pushback with. Delay here is decided on the ground, in the turn, which is why the 11am–2pm window matters as much as it does.
The return leg is a different operation and performs like one: it runs 77.5% on time across 721 flights, 3 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 3 points of difference.
One caution: this is a thin sample. 721 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 PHX
Put together: treat all of this as provisional. 721 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 80.5% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 713 completed flights over 12 months sit behind that.
