These figures cover 203 flights between September 2025 and August 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.

Delay causes
Why SkyWest runs late on this route
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 815 reported delay minutes.
- 38%Late-arriving aircraft
- 31%National Airspace System
- 30%Carrier
38% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 815 reported delay minutes here, that single category outweighs weather by 38 to one. The split is drawn from 815 reported delay minutes.
Cancellations are rare at 0.00%, below the national 1.89% and low enough to earn the plus on the grade. Almost no flights are 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 2.0% 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 752 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 89.7% on time across 203 flights, within 2 points 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. 203 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 FCA
Put together: treat all of this as provisional. 203 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 92.1% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 203 completed flights over 12 months sit behind that.
