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 151 flights.

There are not enough flights in each departure window to split SkyWest's SLC to SNA record by time of day without the percentages moving on noise. The headline rate of 82.0% is the reliable figure here.

SkyWest on SLC to SNA did not run the same all year. Its best quarter was Jan–Mar 2026 at 87.8% on time and its weakest Jul–Sep 2026 at 75.9%, a swing of 12 points on roughly 50 flights a quarter.

Delay causes

Why SkyWest runs late on this route

Carrier accounts for 67% of the 1,802 delay minutes carriers reported here, and the remaining four split what is left.

  • Carrier
    67%
  • Extreme weather
    24%
  • National Airspace System
    9%
  • Security
    0%

Extreme weather accounts for 24% 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 4.0 times the usual weather exposure. The split is drawn from 1,802 reported delay minutes.

The largest share of delay minutes, 67%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,201 of the 1,802 delay minutes reported here.

Cancellations are rare at 0.66%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.

Connections and stage length

What a delay here costs

8.0% of arrivals land an hour or more late, close to the national 8.3%, so 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.

The 588 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.

The return leg runs 84.7% on time across 151 flights, within 3 points of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.

One caution: this is a thin sample. 151 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 SLC to SNA

Put together: treat all of this as provisional. 151 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 82.0% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 150 completed flights over 12 months sit behind that.
