These figures cover 746 flights between September 2025 and August 2026. The median arrival is 14 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.

|---|---|---|
| 29 July 2026 | 10 hours 19 minutes | Carrier |
| 19 March 2026 | 6 hours 48 minutes | Late-arriving aircraft |
| 2 February 2026 | 5 hours 42 minutes | Carrier |

Delay causes
Why SkyWest runs late on this route
Carrier accounts for 56% of the 5,720 delay minutes carriers reported here, and the remaining four split what is left.
- 56%Carrier
- 21%Late-arriving aircraft
- 12%Extreme weather
- 11%National Airspace System
- 0%Security
Extreme weather accounts for 12% 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 2.0 times the usual weather exposure. The split is drawn from 5,720 reported delay minutes.
The largest share of delay minutes, 56%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 3,198 of the 5,720 delay minutes reported here.
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 4.3% 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 844 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 is a different operation and performs like one: it runs 87.8% on time across 748 flights, 3 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 3 points of difference.
One caution: this is a thin sample. 746 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 FAT to DEN
Put together: treat all of this as provisional. 746 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 91.1% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 743 completed flights over 12 months sit behind that.
