SkyWest on DEN to BZN earns an A. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 11 points better than the national rate of 77.6%. When something does go wrong the average delay runs about an hour. That rests on 393 flights. The strongest carrier on the route with a full sample, United Airlines, flew 1,163 at 82.3% on time.

Set against the rest of the country, SkyWest's DEN to BZN record is 11 points better than the US average of 77.6%. That gap is worth roughly 108 fewer late arrivals for every thousand flights.

Every carrier on DEN to BZN, 2,729 flights

These figures cover 393 flights between July 2025 and June 2026. The median arrival is 10 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 DEN to BZN

SkyWest flew 393 of the 2,729 flights on DEN to BZN, about 14% of it. Its 88.4% on time is 10 points better than the route as a whole, which runs 78.1%. Ranked by on-time rate it is first of three carriers on the route, where the range runs from SkyWest at 88.4% to Southwest at 70.5%.

The choice of carrier is not cosmetic here. United Airlines arrives on time 82.3% of the time; Southwest Airlines manages 70.5%. Sample sizes sit next to every figure, because a two-point gap across 1,173 flights means less than a ten-point one.

On-time performance by carrier on DEN to BZN
Airline	Flights	On time	Avg delay	Cancelled	Grade
SkyWest Airlines (this page)	393	88.4%	59 min	1.02%	A
United Airlines	1,163	82.3%	61 min	0.09%	B+
Southwest Airlines	1,173	70.5%	51 min	0.43%	C+

United leads Southwest by 12 points. Real, but small enough that a better departure time on the weaker carrier can outweigh it.

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 20 points, against 12 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

5am–8am43 flights100.0%
8am–11am190 flights90.9%
11am–2pm60 flights86.7%

Scale runs 70% to 100%. Rows with fewer than 30 flights show a dash.

Book the early departure. Flights leaving between 5am–8am arrive on time 100.0% of the time, against 79.6% for the afternoon window. That is 20 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8am–11am window is the busiest, with 190 flights scheduled in it.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 88.4% on time across 393 flights.

Quarter by quarter SkyWest on DEN to BZN held fairly steady: 87.7% in Jul–Sep 2025, 88.1% in Oct–Dec 2025 and 88.3% in Apr–Jun 2026. A spread of half a point is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Across the week, Tuesday is the strongest day at 96.4% on time and Sunday the weakest at 80.4%. 16 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 54% of the 2,647 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.

Extreme weather

The largest share of delay minutes, 54%, 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 1,440 of the 2,647 delay minutes reported here. The split is drawn from 2,647 reported delay minutes.

Cancellations sit at 1.02% against a national 1.81%, which is ordinary. Diversions add another 0.51%.

Connections and stage length

What a delay here costs

Badly late arrivals are rare here: only 3.6% 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.

The 524 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

The return leg is a different operation and performs like one: it runs 77.8% on time across 393 flights, 11 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 11 points of difference.

One caution: this is a thin sample. 393 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 BZN

Put together: treat all of this as provisional. 393 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. 387 completed flights over 12 months sit behind that.
