Every carrier on RNO to SEA, 905 flights
These figures cover 112 flights between September 2025 and August 2026. On-time means an arrival less than 15 minutes after the scheduled gate time, the same threshold the Department of Transportation uses in its own reports. Cancelled and diverted flights are excluded from the on-time rate and counted separately, which is why the cancellation column matters on its own.

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 112 flights.
There are not enough flights in each departure window to split SkyWest's RNO to SEA record by time of day without the percentages moving on noise. The headline rate of 67.9% is the reliable figure here.

The worst days
Worst days for SkyWest on RNO to SEA
The latest arrival of the period was on 21 July 2026, 6 hours 45 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. Four of the five worst days fell in August 2026.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 21 July 2026 | 6 hours 45 minutes | Late-arriving aircraft |
| 1 August 2026 | 1 hour 58 minutes | Extreme weather |
| 13 August 2026 | 1 hour 49 minutes | Carrier |
| 5 August 2026 | 1 hour 48 minutes | National Airspace System |
| 12 August 2026 | 1 hour 44 minutes | Late-arriving aircraft |
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 1,768 reported delay minutes.
- 35%Late-arriving aircraft
- 28%Carrier
- 28%National Airspace System
- 8%Extreme weather
35% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 1,768 reported delay minutes here, that single category outweighs weather by 4 to one. The split is drawn from 1,768 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 63.3% 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
7.1% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about 50 minutes, which a normal layover absorbs.
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 90.2% on time across 113 flights, 22 points above 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. 112 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 SEA
Put together: treat all of this as provisional. 112 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 67.9% 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.
