Historical statistics for July 2025 to June 2026, not live status. For today’s AS 141, check with Alaska Airlines.

AS 141 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 256 flights, with a median arrival 9 minutes early.

These figures cover 256 flights between July 2025 and June 2026. The median arrival is 9 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 141 flies

AS 141 flies PHX to ANC without a single fixed slot. Its most common scheduled departure was 19:57, used on 50 of 256 flights, with 20:59 (44 flights) and 20:48 (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 19:57 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and AS 141 runs 9 points better at 76.7%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Against the route

AS 141 next to PHX to ANC

Across the year

AS 141 quarter by quarter

AS 141 did not run the same all year. Its best quarter was Jan–Mar 2026 at 83.6% on time and its weakest Oct–Dec 2025 at 70.5%, a swing of 13 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 141 did best on Saturday at 89.2% on time and worst on Thursday at 68.8%. Each day rests on about 37 flights, so a gap of 20 points is worth noticing but could still narrow in another year.

Delay causes

Why AS 141 runs late

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 3,909 reported delay minutes.

  • Late-arriving aircraft
    41%
  • Carrier
    37%
  • National Airspace System
    13%
  • Extreme weather
    9%

41% 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 3,909 reported delay minutes here, that single category outweighs weather by 4 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 3,909 delay minutes reported on AS 141.

Cancellations are rare at 0.00%, below the national 1.81% and low enough to earn the plus on the grade. Almost no flights are called off; the risk here is arriving late, not not arriving.

Connections and routes

What a delay on this flight costs

7.9% 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 2,552 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 SEA to HNL (45) and SEA to DFW (1), but none flew often enough under AS 141 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to PHX to ANC only.

One caution: this is a thin sample. 256 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 141

For a booking, read AS 141 as 76.7% on time with 0.00% cancelled over 256 flights. Those are rates from the past twelve months, not a forecast for any particular day.
