These figures cover 113 flights between September 2025 and August 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.

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 113 flights.
There are not enough flights in each departure window to split SkyWest's SEA to RNO record by time of day without the percentages moving on noise. The headline rate of 90.2% is the reliable figure here.

The worst days
Worst days for SkyWest on SEA to RNO
The latest arrival of the period was on 20 August 2026, 2 hours 52 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 20 August 2026 | 2 hours 52 minutes | Late-arriving aircraft |
| 18 August 2026 | 2 hours 28 minutes | Late-arriving aircraft |
| 2 July 2026 | 2 hours 12 minutes | Late-arriving aircraft |

Delay causes
Why SkyWest runs late on this route
Late-arriving aircraft accounts for 73% of the 746 delay minutes carriers reported here, and the remaining four split what is left.
- 73%Late-arriving aircraft
- 16%Carrier
- 7%Extreme weather
- 3%National Airspace System
73% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 746 reported delay minutes here, that single category outweighs weather by 10 to one. The split is drawn from 746 reported delay minutes.
The practical consequence: the 8am–11am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 91.8% on time 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 2.7% 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 564 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 67.9% on time across 112 flights, 22 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 22 points of difference.
One caution: this is a thin sample. 113 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 SEA to RNO
Put together: treat all of this as provisional. 113 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 90.2% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 112 completed flights over 12 months sit behind that.
