Every carrier on SLC to JAC, 1,220 flights
These figures cover 526 flights between July 2025 and June 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.
Carrier by carrier
SkyWest against every carrier on SLC to JAC
SkyWest flew 526 of the 1,220 flights on SLC to JAC, about 43% of it. Its 88.5% on time is about level with the route as a whole at 88.4%. Ranked by on-time rate it is first of two carriers on the route, where the range runs from SkyWest at 88.5% to Delta at 88.2%.
Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

Departure window
When SkyWest runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 15 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 88.5% on time across 526 flights.
SkyWest on SLC to JAC did not run the same all year. Its best quarter was Oct–Dec 2025 at 93.7% on time and its weakest Jan–Mar 2026 at 76.5%, a swing of 17 points on roughly 132 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.
Across the week, Saturday is the strongest day at 94.5% on time and Wednesday the weakest at 82.6%. 12 points is a smaller lever than departure hour, but it is free.
Delay causes
Why SkyWest runs late on this route
One category carries most of the weight here. Carrier accounts for 87% of the 3,979 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.
- 87%Carrier
- 8%Extreme weather
- 5%National Airspace System
The largest share of delay minutes, 87%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 3,470 of the 3,979 delay minutes reported here. The split is drawn from 3,979 reported delay minutes.
Cancellations sit at 1.14% against a national 1.81%, which is ordinary. Diversions add another 0.95%.
Connections and stage length
What a delay here costs
5.0% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says 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.
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 is a different operation and performs like one: it runs 85.3% on time across 524 flights, 3 points below 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 3 points of difference.
One caution: this is a thin sample. 526 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. 526 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 88.5% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 515 completed flights over 12 months sit behind that.
