Delay causes
Why SkyWest runs late on this route
Carrier accounts for 72% of the 5,390 delay minutes carriers reported here, and the remaining four split what is left.
- 72%Carrier
- 24%Extreme weather
- 4%National Airspace System
Extreme weather accounts for 24% 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 4.0 times the usual weather exposure. The split is drawn from 5,390 reported delay minutes.
The largest share of delay minutes, 72%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 3,858 of the 5,390 delay minutes reported here.
Cancellations sit at 1.18% against a national 1.89%, which is ordinary. Diversions add another 0.29%.
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 8.3% 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.
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.
The return leg runs 91.0% on time across 678 flights, within half 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. 678 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 FCA to SLC
Put together: treat all of this as provisional. 678 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 91.2% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 668 completed flights over 12 months sit behind that.
