These figures cover 1,452 flights between September 2025 and August 2026. The median arrival is 10 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 1,452 flights.
- 5am–8am—
- 8am–11am335 flights88.0%
- 11am–2pm154 flights85.7%
- 2pm–5pm248 flights82.6%
- 5pm–8pm294 flights85.3%
- 8pm–5am421 flights86.9%
Scale runs 75% to 95%. Rows with fewer than 30 flights show a dash.
The overnight block holds up unusually well at 86.9% on time across 421 flights. Red-eyes fly into empty airspace and empty gates, and they are the first rotation of the aircraft's day rather than the last. The 8pm–5am window is the busiest, with 421 flights scheduled in it.

SkyWest on SEA to RDM through the year
August is the worst month at 78.0% on time, 14 points below October, the best at 92.2%. Summer afternoon convection and peak-season schedules land on the same weeks every year, so this is a pattern you can book around rather than a run of bad luck. July was the busiest month here, with 153 flights.
Across the week, Saturday is the strongest day at 90.1% on time and Thursday the weakest at 83.0%, a spread of 7 points.

Delay causes
Why SkyWest runs late on this route
Carrier accounts for 46% of the 11,000 delay minutes carriers reported here, and the remaining four split what is left.
- 46%Carrier
- 24%Extreme weather
- 17%Late-arriving aircraft
- 13%National Airspace System
Extreme weather accounts for 24% 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 4.1 times the usual weather exposure. The split is drawn from 10,608 reported delay minutes.
The largest share of delay minutes, 46%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 4,908 of the 11,000 delay minutes reported here.
Cancellations sit at 1.72% against a national 1.89%, which is ordinary. Diversions add another 0.28%.
Connections and stage length
What a delay here costs
Badly late arrivals are rare here: only 3.3% 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.
At 228 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 85.6% on time across 1,453 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.
The sample behind these figures is 1,452 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.
What to do with this
Booking SkyWest on SEA to RDM
Put together: the calendar is the biggest lever here, not the carrier or the hour. October runs 92.2% on time and August 78.0%, a swing of 14 points. If the dates move at all, move them out of August before you think about anything else. 1,423 completed flights over 12 months sit behind that.
