These figures cover 464 flights between September 2025 and August 2026. The median arrival is 3 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 matters more here than the choice of carrier. The gap between the best and worst window is 13 points, against half a point between the best and worst carrier.
- 5am–8am84 flights86.9%
- 8am–11am21 flights—
- 11am–2pm—
- 2pm–5pm256 flights87.1%
- 5pm–8pm95 flights73.7%
- 8pm–5am8 flights—
Scale runs 65% to 95%. Rows with fewer than 30 flights show a dash.
The best window here is not the first bank but the 2pm–5pm slot at 87.1% on time, ahead of 5pm–8pm at 73.7%. Where the curve peaks mid-day rather than at dawn, the constraint is usually congestion at one end rather than the aircraft's own rotation. The 2pm–5pm window is the busiest, with 256 flights scheduled in it.
Across the year
SkyWest on PDX to GEG through the year
January is the weak month at 71.0% on time, against 93.3% in April. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. December was the busiest month here, with 74 flights.
Across the week, Thursday is the strongest day at 89.2% on time and Tuesday the weakest at 76.5%, a spread of 13 points.

Worst days for SkyWest on PDX to GEG
The latest arrival of the period was on 12 January 2026, 3 hours 33 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 |
|---|---|---|
| 12 January 2026 | 3 hours 33 minutes | Late-arriving aircraft |
| 1 March 2026 | 3 hours 6 minutes | Late-arriving aircraft |

Delay causes
Why SkyWest runs late on this route
Late-arriving aircraft accounts for 59% of the 3,272 delay minutes carriers reported here, and the remaining four split what is left.
- 59%Late-arriving aircraft
- 23%Carrier
- 10%Extreme weather
- 8%National Airspace System
59% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,272 reported delay minutes here, that single category outweighs weather by 6 to one. The split is drawn from 3,272 reported delay minutes.
Cancellations are rare at 0.22%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is 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 3.5% 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 279 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 2pm–5pm window matters as much as it does.
The return leg is a different operation and performs like one: it runs 77.0% on time across 463 flights, 7 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 7 points of difference.
One caution: this is a thin sample. 464 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 PDX to GEG
Put together: treat all of this as provisional. 464 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 84.2% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 463 completed flights over 12 months sit behind that.
