These figures cover 478 flights between September 2025 and August 2026. The median arrival is 8 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
Carrier accounts for 87% of the 4,642 delay minutes carriers reported here, and the remaining four split what is left.
- 87%Carrier
- 7%Extreme weather
- 6%National Airspace System
The largest share of delay minutes, 87%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 4,049 of the 4,642 delay minutes reported here. The split is drawn from 4,642 reported delay minutes.
Cancellations sit at 1.26% against a national 1.89%, which is ordinary. Diversions add another 1.05%.
Connections and stage length
What a delay here costs
6.6% 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 a little over an hour, which a normal layover absorbs.
At 205 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 8pm–5am window matters as much as it does.
The return leg runs 84.6% on time across 475 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. 478 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 JAC
Put together: treat all of this as provisional. 478 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 86.1% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 467 completed flights over 12 months sit behind that.
