These figures cover 470 flights between September 2025 and August 2026. The median arrival is 11 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
Departure time is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 470 flights.
- 5am–8am—
- 8am–11am329 flights94.0%
- 11am–2pm89 flights87.1%
- 2pm–5pm52 flights90.0%
- 5pm–8pm—
- 8pm–5am—
Scale runs 80% to 100%. Rows with fewer than 30 flights show a dash.
The weak window here is the middle of the day, not the evening: 11am–2pm runs 87.1% on time against 94.0% for 8am–11am. That shape usually means a departure bank rather than an accumulating delay, so the recovery later in the afternoon is real rather than noise. The 8am–11am window is the busiest, with 329 flights scheduled in it.
Across the year
SkyWest on DEN to JAC through the year
December is the weak month at 81.0% on time, against 97.2% in September. 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. October was the busiest month here, with 62 flights.
Across the week, Tuesday is the strongest day at 96.8% on time and Saturday the weakest at 87.8%, a spread of 9 points.

Delay causes
Why SkyWest runs late on this route
Carrier accounts for 49% of the 1,509 delay minutes carriers reported here, and the remaining four split what is left.
- 49%Carrier
- 27%Late-arriving aircraft
- 22%National Airspace System
- 3%Extreme weather
The largest share of delay minutes, 49%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 732 of the 1,509 delay minutes reported here. The split is drawn from 1,509 reported delay minutes.
Cancellations sit at 2.34% against a national 1.89%, which is ordinary. Diversions add another 1.49%.
Connections and stage length
What a delay here costs
Badly late arrivals are rare here: only 2.0% 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.
At 406 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 8am–11am window matters as much as it does.
The return leg is a different operation and performs like one: it runs 88.0% on time across 470 flights, 4 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 4 points of difference.
One caution: this is a thin sample. 470 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 DEN to JAC
Put together: treat all of this as provisional. 470 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 92.3% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 452 completed flights over 12 months sit behind that.
