Historical statistics for July 2025 to June 2026, not live status. For today’s AS 561, check with Alaska Airlines.

AS 561 lands a B+, level with the national rate of 77.6%. Roughly one flight in four arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 341 flights, with a median arrival 6 minutes early.

These figures cover 341 flights between July 2025 and June 2026. The median arrival is 6 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 561 flies

AS 561 flies KOA to LAX without a single fixed slot. Its most common scheduled departure was 13:20, used on 50 of 341 flights, with 15:19 (45 flights) and 14:36 (37 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 13:20 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and AS 561 runs level with that at 77.2%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

AS 561 quarter by quarter

AS 561 did not run the same all year. Its best quarter was Apr–Jun 2026 at 84.3% on time and its weakest Oct–Dec 2025 at 70.1%, a swing of 14 points on roughly 85 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 561 did best on Wednesday at 85.4% on time and worst on Thursday at 63.8%. Each day rests on about 49 flights, so a gap of 22 points is worth noticing but could still narrow in another year.

Delay causes

Why AS 561 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 62% of the 4,413 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.

62% 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 4,413 reported delay minutes here, that single category outweighs weather by 62 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 4,413 delay minutes reported on AS 561.

Cancellations are rare at 0.88%, below the national 1.81% 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

6.2% 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 about an hour, which a normal layover absorbs.

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 one other city pair in the data, including MSO to SEA (20), 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. 341 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: 10 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.
