Historical statistics for July 2025 to June 2026, not live status. For today’s AS 60, check with Alaska Airlines.
AS 60 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 an hour and a half. That rests on 362 flights, with a median arrival 11 minutes early.
Set against the rest of the country, AS 60's record is 7 points better than the US average of 77.6%. That gap is worth roughly 71 fewer late arrivals for every thousand flights.

These figures cover 362 flights between July 2025 and June 2026. The median arrival is 11 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 60 flies
AS 60 flies KTN to SEA without a single fixed slot. Its most common scheduled departure was 09:00, used on 95 of 362 flights, with 09:20 (69 flights) and 09:12 (46 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.
Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 09:00 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and AS 60 runs level with that at 84.7%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.
Against the route
AS 60 next to KTN to SEA
Every carrier on KTN to SEA combined arrived on time 82.6% of the time across 1,304 flights, so AS 60 is 2 points ahead of it. Across its whole network Alaska Airlines managed 79.1%, which this flight beats by 6 points.

Across the year
AS 60 quarter by quarter
AS 60 did not run the same all year. Its best quarter was Apr–Jun 2026 at 96.7% on time and its weakest Oct–Dec 2025 at 77.0%, a swing of 20 points on roughly 91 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.

By weekday, AS 60 did best on Saturday at 90.4% on time and worst on Monday at 74.5%. Each day rests on about 52 flights, so a gap of 16 points is worth noticing but could still narrow in another year.
Delay causes
Why AS 60 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 52% of the 4,737 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.

- 35%Carrier
- 9%National Airspace System
- 2%Extreme weather
- 1%Security
52% 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 4,737 reported delay minutes here, that single category outweighs weather by 22 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 4,737 delay minutes reported on AS 60.
Cancellations sit at 2.49% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
5.7% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last an hour and a half, which a normal layover absorbs.
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 60 is not only a KTN to SEA flight. It also flew JNU to KTN (361 flights, 84.7% 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. 362 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.
