Historical statistics for July 2025 to June 2026, not live status. For today’s AS 271, check with Alaska Airlines.

AS 271 lands a B+, about a point worse than the national rate of 77.6%. About 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 342 flights, with a median arrival 3 minutes early.

These figures cover 342 flights between July 2025 and June 2026. The median arrival is 3 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 271 flies

AS 271 flies HNL to ONT without a single fixed slot. Its most common scheduled departure was 12:55, used on 50 of 342 flights, with 12:38 (45 flights) and 14:54 (36 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 12:55 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and AS 271 runs 2 points worse at 76.8%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

AS 271 quarter by quarter

AS 271 did not run the same all year. Its best quarter was Apr–Jun 2026 at 89.9% on time and its weakest Oct–Dec 2025 at 67.0%, a swing of 23 points on roughly 86 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 271 did best on Thursday at 91.7% on time and worst on Saturday at 70.8%. Each day rests on about 49 flights, so a gap of 21 points is worth noticing but could still narrow in another year.

Delay causes

Why AS 271 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 44% of the 4,977 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.

  • Carrier
    39%
  • National Airspace System
    14%
  • Extreme weather
    3%
  • Security
    0%

44% 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 4,977 reported delay minutes here, that single category outweighs weather by 16 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 4,977 delay minutes reported on AS 271.

Cancellations are rare at 0.29%, 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

7.6% 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 2,603 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 PDX to ANC (21), but none flew often enough under AS 271 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to HNL to ONT only.

One caution: this is a thin sample. 342 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 271

For a booking, read AS 271 as 76.8% on time with 0.29% cancelled over 342 flights. Those are rates from the past twelve months, not a forecast for any particular day.
