Across the year
AS 67 quarter by quarter
Quarter by quarter AS 67 held fairly steady: 63.6% in Oct–Dec 2025, 64.3% in Jan–Mar 2026, 73.3% in Apr–Jun 2026 and 67.7% 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 202591 flights63.6%
- Jan–Mar 202690 flights64.3%
- Apr–Jun 202691 flights73.3%

Scale runs 55% to 80%. Rows with fewer than 30 flights show a dash.
By weekday, AS 67 did best on Wednesday at 75.0% on time and worst on Thursday at 60.0%. Each day rests on about 52 flights, so a gap of 15 points is worth noticing but could still narrow in another year.

Share of 352 completed flights by arrival against schedule.
17 of 104 late departures made up the time and arrived on time, 16% of them. In the other direction, 22 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 KTN.
The worst days
Worst days for AS 67
The latest arrival of the period was on 23 October 2025, 5 hours 24 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 23 October 2025 | 5 hours 24 minutes | Carrier |
| 28 March 2026 | 4 hours 48 minutes | Carrier |
| 13 March 2026 | 4 hours 43 minutes | Late-arriving aircraft |

Delay causes
Why AS 67 runs late
Carrier accounts for 59% of the 6,126 delay minutes carriers reported here, and the remaining four split what is left.
- 59%Carrier
- 24%Late-arriving aircraft
- 14%National Airspace System
- 3%Extreme weather
- 0%Security
The largest share of delay minutes, 59%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 3,642 of the 6,126 delay minutes reported here. The split is drawn from 6,126 delay minutes reported on AS 67.
Cancellations are rare at 0.55%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.
Connections and routes
What a delay on this flight costs
8.8% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, 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.
AS 67 is not only a SEA to KTN flight. It also flew KTN to SIT (364 flights, 74.1% on time), JNU to ANC (362 flights, 81.0% on time) and SIT to JNU (362 flights, 79.5% 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. 364 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.
