Historical statistics for July 2025 to June 2026, not live status. For today’s AS 64, check with Alaska Airlines.
AS 64 earns a B−. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 7 points better than the national rate of 77.6%. 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 7 points better than the US average of 77.6%. That gap is worth roughly 68 fewer late arrivals for every thousand flights.

These figures cover 359 flights between July 2025 and June 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.
Schedule
When AS 64 flies
AS 64 flies KTN to SEA without a single fixed slot. Its most common scheduled departure was 17:49, used on 69 of 359 flights, with 17:40 (50 flights) and 17:37 (45 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 17:49 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and AS 64 runs 16 points better at 84.4%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.
Against the route
AS 64 next to KTN to SEA

Across the year
AS 64 quarter by quarter
AS 64 did not run the same all year. Its best quarter was Apr–Jun 2026 at 90.0% on time and its weakest Jul–Sep 2025 at 77.8%, a swing of 12 points on roughly 90 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

- Oct–Dec 202589 flights89.4%
- Jan–Mar 202688 flights80.2%

Scale runs 70% to 95%. Rows with fewer than 30 flights show a dash.
By weekday, AS 64 did best on Wednesday at 90.2% on time and worst on Saturday at 77.1%. Each day rests on about 51 flights, so a gap of 13 points is worth noticing but could still narrow in another year.
Delay causes
Why AS 64 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 78% of the 3,497 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.
- 78%Late-arriving aircraft
- 11%Carrier
- 10%National Airspace System
- 1%Extreme weather
78% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 3,497 reported delay minutes here, that single category outweighs weather by 78 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 3,497 delay minutes reported on AS 64.
Cancellations run at 3.62%, against 1.81% 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 4.9% land an hour or more behind schedule, against 8.1% 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
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.
