These figures cover 605 flights between September 2025 and August 2026. The median arrival is 6 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 Alaska runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 12 points, against half a point between the best and worst carrier.
- 5am–8am293 flights96.2%
- 8am–11am3 flights—
- 11am–2pm297 flights84.2%
- 2pm–5pm—
- 5pm–8pm12 flights—
- 8pm–5am—
Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.
The weak window here is the middle of the day, not the evening: 11am–2pm runs 84.2% on time against 96.2% for 5am–8am. That shape usually means a departure bank rather than an accumulating delay, so the recovery later in the afternoon is real rather than noise. The 11am–2pm window is the busiest, with 297 flights scheduled in it.
Across the year
Alaska on GEG to PDX through the year
December is the weak month at 84.2% on time, against 98.1% in November. 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. July was the busiest month here, with 62 flights.
Across the week, Sunday is the strongest day at 95.3% on time and Thursday the weakest at 86.4%, a spread of 9 points.

The worst days
Worst days for Alaska on GEG to PDX
The latest arrival of the period was on 7 August 2026, 12 hours 24 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. On four of the five worst days the largest share was filed as carrier-caused (crew, maintenance, fuelling, baggage).
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 7 August 2026 | 12 hours 24 minutes | Late-arriving aircraft |
| 4 June 2026 | 4 hours 19 minutes | Carrier |

Delay causes
Why Alaska runs late on this route
Late-arriving aircraft accounts for 52% of the 3,340 delay minutes carriers reported here, and the remaining four split what is left.
- 52%Late-arriving aircraft
- 41%Carrier
- 7%National Airspace System
52% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,340 reported delay minutes here, that single category outweighs weather by 52 to one. The split is drawn from 3,340 reported delay minutes.
The largest share of delay minutes, 41%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,355 of the 3,340 delay minutes reported here.
Cancellations sit at 1.16% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and stage length
What a delay here costs
Badly late arrivals are rare here: only 2.0% 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 5am–8am window matters as much as it does.
The return leg is a different operation and performs like one: it runs 85.1% on time across 605 flights, 5 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 5 points of difference.
One caution: this is a thin sample. 605 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 Alaska on GEG to PDX
Put together: treat all of this as provisional. 605 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 90.3% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 598 completed flights over 12 months sit behind that.
