These figures cover 504 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.

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 504 flights.
- 5am–8am—
- 8am–11am—
- 11am–2pm76 flights94.7%
- 2pm–5pm96 flights93.8%
- 5pm–8pm332 flights85.4%
- 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 94.7% on time, ahead of 5pm–8pm at 85.4%. 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 5pm–8pm window is the busiest, with 332 flights scheduled in it.
Across the year
SkyWest on BZN to SLC through the year
Delays peak in March, when the on-time rate falls to 68.4%. January is the strongest month at 96.5%. Moving a flexible trip across that boundary buys 28 points. January was the busiest month here, with 57 flights.
Across the week, Tuesday is the strongest day at 90.9% on time and Saturday the weakest at 81.0%. 10 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 60% of the 5,610 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.
- 60%Carrier
- 35%Extreme weather
- 5%National Airspace System
Extreme weather accounts for 35% 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 5.6 times the usual weather exposure. The split is drawn from 5,610 reported delay minutes.
The largest share of delay minutes, 60%, 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 3,338 of the 5,610 delay minutes reported here.
Cancellations are rare at 0.79%, below the national 1.81% 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 3.2% land an hour or more behind schedule, against 8.1% 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 347 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 runs 87.5% on time across 504 flights, within about a point 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. 504 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 BZN to SLC
Put together: treat all of this as provisional. 504 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 88.4% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 500 completed flights over 12 months sit behind that.
