Historical statistics for September 2025 to August 2026, not live status. For today’s AS 64, check with Alaska Airlines.
AS 64 earns an A−. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 9 points better than the national rate of 77.3%. When something does go wrong the average delay runs about an hour. That rests on 359 flights, with a median arrival 14 minutes early.
Set against the rest of the country, AS 64's record is 9 points better than the US average of 77.3%. That gap is worth roughly 88 fewer late arrivals for every thousand flights.

These figures cover 359 flights between September 2025 and August 2026. The median arrival is 14 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.

Across the year
AS 64 quarter by quarter
Quarter by quarter AS 64 held fairly steady: 89.4% in Oct–Dec 2025, 80.2% in Jan–Mar 2026, 90.0% in Apr–Jun 2026 and 85.2% in Jul–Sep 2026. A spread of 10 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

- Oct–Dec 202589 flights89.4%
- Jan–Mar 202688 flights80.2%
- Apr–Jun 202690 flights90.0%

Scale runs 70% to 95%. Rows with fewer than 30 flights show a dash.
By weekday, AS 64 did best on Tuesday at 92.0% on time and worst on Saturday at 79.6%. Each day rests on about 51 flights, so a gap of 12 points is worth noticing but could still narrow in another year.

The worst days
Worst days for AS 64
The latest arrival of the period was on 23 October 2025, 5 hours 21 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on five of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 23 October 2025 | 5 hours 21 minutes | Late-arriving aircraft |
| 31 January 2026 | 4 hours 6 minutes | Late-arriving aircraft |
| 1 February 2026 | 3 hours 4 minutes | Late-arriving aircraft |
| 25 April 2026 | 3 hours 2 minutes | Late-arriving aircraft |
| 26 September 2025 | 2 hours 21 minutes | Late-arriving aircraft |
Delay causes
Why AS 64 runs late
Late-arriving aircraft accounts for 71% of the 2,900 delay minutes carriers reported here, and the remaining four split what is left.
- 71%Late-arriving aircraft
- 16%Carrier
- 11%National Airspace System
- 1%Extreme weather
71% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 2,900 reported delay minutes here, that single category outweighs weather by 71 to one. The split is drawn from 2,900 delay minutes reported on AS 64.
Cancellations run at 3.62%, against 1.89% nationally. That is about one flight in 30 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 3.8% 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.
The 680 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.
AS 64 is not only a KTN to SEA flight. It also flew ANC to JNU (359 flights, 86.3% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.
One caution: this is a thin sample. 359 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 AS 64
For a booking, the cancellation rate is the figure to plan around on AS 64: 3.62% of its 359 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
