These figures cover 471 flights between September 2025 and August 2026. The median arrival is 13 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
Carrier accounts for 84% of the 3,492 delay minutes carriers reported here, and the remaining four split what is left.
- 84%Carrier
- 11%Extreme weather
- 4%National Airspace System
Extreme weather accounts for 11% 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 1.9 times the usual weather exposure. The split is drawn from 3,492 reported delay minutes.
The largest share of delay minutes, 84%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,948 of the 3,492 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 2.5% 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.
At 422 miles this is a short hop, and stage length matters more than it looks. A flight this short spends under two hours in the air, which leaves almost nothing to claw back a late pushback with. Delay here is decided on the ground, in the turn, which is why the 8am–11am window matters as much as it does.
The return leg runs 90.2% on time across 471 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. 471 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 RNO to SLC
Put together: treat all of this as provisional. 471 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 90.4% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 471 completed flights over 12 months sit behind that.
