These figures cover 292 flights between September 2025 and August 2026. The median arrival is 8 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 561 quarter by quarter
AS 561 did not run the same all year. Its best quarter was Jul–Sep 2025 at 96.7% on time and its weakest Oct–Dec 2025 at 70.1%, a swing of 27 points on roughly 73 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.

Delay causes
Why AS 561 runs late
Late-arriving aircraft accounts for 61% of the 3,083 delay minutes carriers reported here, and the remaining four split what is left.
- 61%Late-arriving aircraft
- 27%Carrier
- 11%National Airspace System
- 1%Extreme weather
61% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,083 reported delay minutes here, that single category outweighs weather by 61 to one. The split is drawn from 3,083 delay minutes reported on AS 561.
Cancellations sit at 1.03% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 4.8% 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.
At 2,504 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 two other city pairs in the data, including SNA to SFO (38) and MSO to SEA (25), but none flew often enough under AS 561 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to KOA to LAX only.
One caution: this is a thin sample. 292 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 561
For a booking, AS 561 is one of the weaker ways to fly KOA to LAX: 8 points below the route as a whole. If the schedule allows, compare it with the other departures listed on the route page before settling on this one.
