These figures cover 903 flights between July 2025 and June 2026. The median arrival is 15 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 SBA to SLC

SkyWest flew 903 of the 1,060 flights on SBA to SLC, most of the route. Its 96.0% on time is about level with the route as a whole at 95.2%. Ranked by on-time rate it is first of two carriers on the route, where the range runs from SkyWest at 96.0% to Delta at 90.8%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.

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 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 903 flights.

5am–8am365 flights97.8%
8am–11am—
11am–2pm334 flights93.7%
2pm–5pm116 flights97.4%
5pm–8pm88 flights95.4%
8pm–5am—

Scale runs 85% to 100%. Rows with fewer than 30 flights show a dash.

The early departures do better, though not dramatically: 97.8% on time for the 5am–8am window against 93.7% for 11am–2pm. Worth taking if the schedule allows, not worth an extra connection. The 5am–8am window is the busiest, with 365 flights scheduled in it.

Across the year

SkyWest on SBA to SLC through the year

Darker means more delays. Figures are on-time percentages.October best, February worst

February is the weak month at 92.5% on time, against 100.0% in October. 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. May was the busiest month here, with 93 flights.

Across the week, Tuesday is the strongest day at 97.7% on time and Saturday the weakest at 93.0%. 5 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. Extreme weather accounts for 61% of the 3,763 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
61%

37%
National Airspace System

Extreme weather accounts for 61% 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 9.8 times the usual weather exposure. The split is drawn from 3,763 reported delay minutes.

The largest share of delay minutes, 37%, 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 1,382 of the 3,763 delay minutes reported here.

Cancellations sit at 1.00% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and stage length

What a delay here costs

Badly late arrivals are rare here: only 1.7% 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 615 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 runs 94.8% on time across 903 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. 903 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 SBA to SLC

Put together: treat all of this as provisional. 903 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 96.0% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 894 completed flights over 12 months sit behind that.
