These figures cover 265 flights between September 2025 and August 2026. The median arrival is 10 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.

A 10:37 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 83.9%, and AS 266 runs 7 points worse at 77.1%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year
AS 266 quarter by quarter
AS 266 did not run the same all year. Its best quarter was Jul–Sep 2026 at 88.7% on time and its weakest Jan–Mar 2026 at 60.9%, a swing of 28 points on roughly 88 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.

- Apr–Jun 202691 flights87.8%

Scale runs 50% to 95%. Rows with fewer than 30 flights show a dash.
By weekday, AS 266 did best on Tuesday at 94.6% on time and worst on Sunday at 68.4%. Each day rests on about 38 flights, so a gap of 26 points is worth noticing but could still narrow in another year.
Arrival by arrival
How late AS 266 runs when it is late

Share of 262 completed flights by arrival against schedule.
9 of 51 late departures made up the time and arrived on time, 18% of them. In the other direction, 18 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 SAN.
The worst days
Worst days for AS 266
The latest arrival of the period was on 28 November 2025, 5 hours 15 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). On three of the five worst days the largest share was filed as a late-arriving aircraft.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 28 November 2025 | 5 hours 15 minutes | Carrier |
| 21 August 2026 | 4 hours 20 minutes | Carrier |
| 20 June 2026 | 3 hours 29 minutes | Late-arriving aircraft |
| 28 January 2026 | 3 hours 11 minutes | Late-arriving aircraft |
| 21 February 2026 | 2 hours 59 minutes | Late-arriving aircraft |
Delay causes
Why AS 266 runs late
Late-arriving aircraft accounts for 47% of the 3,867 delay minutes carriers reported here, and the remaining four split what is left.
- 47%Late-arriving aircraft
- 25%Carrier
- 24%National Airspace System
- 4%Extreme weather
47% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,867 reported delay minutes here, that single category outweighs weather by 12 to one. The split is drawn from 3,867 delay minutes reported on AS 266.
Cancellations are rare at 0.38%, 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
6.5% 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.
At 2,556 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 same number turns up on one other city pair in the data, including ANC to SFO (33), but none flew often enough under AS 266 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to KOA to SAN only.
One caution: this is a thin sample. 265 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 266
For a booking, read AS 266 as 77.1% on time with 0.38% cancelled over 265 flights. Those are rates from the past twelve months, not a forecast for any particular day.
