These figures cover 934 flights between September 2025 and August 2026. The median arrival is 15 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.

Delay causes
Why SkyWest runs late on this route
Extreme weather accounts for 65% of the 4,582 delay minutes carriers reported here, and the remaining four split what is left.
- 65%Extreme weather
- 33%Carrier
- 1%National Airspace System
Extreme weather accounts for 65% 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 10.8 times the usual weather exposure. The split is drawn from 4,582 reported delay minutes.
Cancellations are rare at 0.54%, 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
Badly late arrivals are rare here: only 2.4% 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 615 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 92.9% on time across 934 flights, within 2 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. 934 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 SBA to SLC
Put together: treat all of this as provisional. 934 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 94.8% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 929 completed flights over 12 months sit behind that.
