SkyWest on JAC to SLC earns an A. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 8 points better than the national rate of 77.6%. When something does go wrong the average delay runs a little over an hour. That rests on 524 flights, with a median arrival 8 minutes early.
Set against the rest of the country, SkyWest's JAC to SLC record is 8 points better than the US average of 77.6%. That gap is worth roughly 77 fewer late arrivals for every thousand flights.

These figures cover 524 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 JAC to SLC
SkyWest flew 524 of the 1,218 flights on JAC to SLC, about 43% of it. Its 85.3% on time is 2 points worse than the route as a whole, which runs 87.4%. Ranked by on-time rate it is last of two carriers on the route, where the range runs from Delta at 89.0% to SkyWest at 85.3%.
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.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Delta Air Lines | 694 | 89.0% | 100 min | 0.72% | A+ |
| SkyWest Airlines (this page) | 524 | 85.3% | 80 min | 1.15% | A |
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 14 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am218 flights81.4%
- 8am–11am—
- 11am–2pm125 flights95.2%
- 2pm–5pm1 flights—
- 5pm–8pm180 flights83.1%
- 8pm–5am—
Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.
The best window here is not the first bank but the 11am–2pm slot at 95.2% on time, ahead of 5am–8am at 81.4%. Where the curve peaks mid-day rather than at dawn, the constraint is usually congestion at one end rather than the aircraft's own rotation. The 5am–8am window is the busiest, with 218 flights scheduled in it.
Across the year
SkyWest on JAC to SLC through the year
Delays peak in April, when the on-time rate falls to 73.3%. June is the strongest month at 93.2%. Moving a flexible trip across that boundary buys 20 points. July was the busiest month here, with 93 flights.
Across the week, Saturday is the strongest day at 90.5% on time and Wednesday the weakest at 78.6%. 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 61% of the 6,093 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.
- 61%Carrier
- 29%Extreme weather
- 10%National Airspace System
Extreme weather accounts for 29% 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 4.6 times the usual weather exposure. The split is drawn from 6,093 reported delay minutes.
The largest share of delay minutes, 61%, 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 3,744 of the 6,093 delay minutes reported here.
Cancellations sit at 1.15% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
Connections and stage length
What a delay here costs
5.8% 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 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 11am–2pm window matters as much as it does.
The return leg is a different operation and performs like one: it runs 88.5% on time across 526 flights, 3 points above 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. 524 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 JAC to SLC
Put together: treat all of this as provisional. 524 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 85.3% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 518 completed flights over 12 months sit behind that.
