These figures cover 747 flights between July 2025 and June 2026. The median arrival is 7 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 SLC to FCA
SkyWest flew 747 of the 1,159 flights on SLC to FCA, most of the route. Its 92.8% on time is 2 points better than the route as a whole, which runs 90.5%. Ranked by on-time rate it is first of two carriers on the route, where the range runs from SkyWest at 92.8% to Delta at 86.3%.

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 747 flights.
- 5am–8am—
- 8am–11am332 flights95.1%
- 11am–2pm69 flights95.7%
- 2pm–5pm346 flights90.1%
- 5pm–8pm—
- 8pm–5am—
Scale runs 80% 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 95.7% on time, ahead of 2pm–5pm at 90.1%. 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 2pm–5pm window is the busiest, with 346 flights scheduled in it.
Across the year
SkyWest on SLC to FCA through the year
January is the weak month at 88.7% on time, against 96.7% 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. July was the busiest month here, with 88 flights.
Across the week, Saturday is the strongest day at 98.8% on time and Sunday the weakest at 89.7%. 9 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 2,423 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
- 30%Extreme weather
- 11%National Airspace System
Extreme weather accounts for 30% 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 4.8 times the usual weather exposure. The split is drawn from 2,423 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 1,446 of the 2,423 delay minutes reported here.
Cancellations are rare at 0.80%, 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 1.5% 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 532 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 93.8% on time across 747 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. 747 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 SLC to FCA
Put together: treat all of this as provisional. 747 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 92.8% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 739 completed flights over 12 months sit behind that.
