SkyWest on PHX to PSP sits in the middle of the pack with a B. Close to three flights in four arrive on time by the DOT's definition, 2 points worse than the national rate of 77.3%. The late ones land a little over an hour behind schedule. That rests on 684 flights, with a median arrival 3 minutes early.

The US average over the same twelve months is 77.3%, so there is little to separate SkyWest on PHX to PSP from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Book the morning departure. Flights leaving between 8am–11am arrive on time 85.2% of the time, against 66.1% for the overnight window. That is 19 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on.

Delay causes

Why SkyWest runs late on this route

Carrier accounts for 42% of the 13,000 delay minutes carriers reported here, and the remaining four split what is left.

  • Carrier
    42%
  • Late-arriving aircraft
    42%
  • Extreme weather
    9%
  • National Airspace System
    7%

42% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 13,000 reported delay minutes here, that single category outweighs weather by 5 to one. The split is drawn from 13,294 reported delay minutes.

The largest share of delay minutes, 42%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 5,593 of the 13,000 delay minutes reported here.

Cancellations sit at 1.17% against a national 1.89%, which is ordinary. Diversions add another 0.44%.

Connections and stage length

What a delay here costs

10.8% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection 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 8am–11am window matters as much as it does.

The return leg is a different operation and performs like one: it runs 81.5% on time across 684 flights, 6 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 6 points of difference.

One caution: this is a thin sample. 684 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 PHX to PSP

Put together: treat all of this as provisional. 684 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 75.8% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 673 completed flights over 12 months sit behind that.
