These figures cover 828 flights between September 2025 and August 2026. The median arrival is 14 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

- 5am–8am16 flights—
- 8am–11am109 flights98.2%
- 11am–2pm284 flights92.3%

- 5pm–8pm338 flights91.7%
- 8pm–5am—
Scale runs 85% to 100%. Rows with fewer than 30 flights show a dash.
The early departures do better, though not dramatically: 98.2% on time for the 8am–11am window against 91.7% for 5pm–8pm. Worth taking if the schedule allows, not worth an extra connection. The 5pm–8pm window is the busiest, with 338 flights scheduled in it.
Across the year
SkyWest on PSC to SLC through the year
February is the weak month at 84.0% on time, against 100.0% in June. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. July was the busiest month here, with 89 flights.
Across the week, Monday is the strongest day at 96.0% on time and Thursday the weakest at 90.0%, a spread of 6 points.

Delay causes
Why SkyWest runs late on this route
Carrier accounts for 62% of the 4,332 delay minutes carriers reported here, and the remaining four split what is left.
- 62%Carrier
- 36%Extreme weather
- 3%National Airspace System
Extreme weather accounts for 36% 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 5.9 times the usual weather exposure. The split is drawn from 4,332 reported delay minutes.
The largest share of delay minutes, 62%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,669 of the 4,332 delay minutes reported here.
Cancellations are rare at 0.00%, below the national 1.89% and low enough to earn the plus on the grade. Almost no flights are called off; the risk here is arriving late, not not arriving.
Connections and stage length
What a delay here costs
Badly late arrivals are rare here: only 2.3% land an hour or more behind schedule, against 8.3% 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 521 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 90.6% on time across 829 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. 828 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 PSC to SLC
Put together: treat all of this as provisional. 828 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 93.1% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 827 completed flights over 12 months sit behind that.
