These figures cover 374 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 Alaska 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 374 flights.
- 5am–8am253 flights84.3%
- 8am–11am111 flights76.5%
- 11am–2pm—
- 2pm–5pm—
- 5pm–8pm—
- 8pm–5am10 flights—
Scale runs 70% to 90%. Rows with fewer than 30 flights show a dash.
The early departures do better, though not dramatically: 84.3% on time for the 5am–8am window against 76.5% for 8am–11am. Worth taking if the schedule allows, not worth an extra connection. The 5am–8am window is the busiest, with 253 flights scheduled in it.
Across the year
Alaska on PDX to JFK through the year
June is the worst month at 70.0% on time, 27 points below May, the best at 96.7%. 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. August was the busiest month here, with 41 flights.
Across the week, Saturday is the strongest day at 94.1% on time and Thursday the weakest at 70.6%, a spread of 24 points.

Share of 360 completed flights by arrival against schedule.
A late pushback is often recovered here: of 41 departures that left 15 minutes late or more, 13 still arrived on time. In the other direction, 35 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at JFK.
The worst days
Worst days for Alaska on PDX to JFK
The latest arrival of the period was on 14 June 2026, 4 hours 26 minutes behind schedule; most of its delay minutes were filed as national airspace system delay. Three of the five worst days fell in June 2026.

| 14 June 2026 | 4 hours 26 minutes | National Airspace System |
| 6 July 2026 | 3 hours 47 minutes | National Airspace System |
| 9 July 2026 | 3 hours 21 minutes | National Airspace System |

Delay causes
Why Alaska runs late on this route
National Airspace System accounts for 90% of the 3,763 delay minutes carriers reported here, and the remaining four split what is left.
- 90%National Airspace System
- 6%Carrier
- 4%Late-arriving aircraft
- 1%Extreme weather
- 0%Security
90% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 3,377 minutes out of 3,763, against a national NAS share of 21%. The split is drawn from 3,763 reported delay minutes.
Cancellations sit at 1.87% against a national 1.89%, which is ordinary. Diversions add another 1.87%.
Connections and stage length
What a delay here costs
Badly late arrivals are rare here: only 4.2% 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 2,454 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.
The return leg is a different operation and performs like one: it runs 73.2% on time across 374 flights, 9 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 9 points of difference.
One caution: this is a thin sample. 374 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 PDX to JFK
Put together: treat all of this as provisional. 374 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 82.5% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 360 completed flights over 12 months sit behind that.
