These figures cover 291 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 1455 flies

AS 1455 flies PDX to ANC without a single fixed slot. Its most common scheduled departure was 17:50, used on 102 of 291 flights, with 17:49 (50 flights) and 17:45 (45 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 17:50 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and AS 1455 runs 16 points better at 84.1%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year

AS 1455 quarter by quarter

AS 1455 did not run the same all year. Its best quarter was Apr–Jun 2026 at 97.1% on time and its weakest Jul–Sep 2025 at 78.3%, a swing of 19 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.

By weekday, AS 1455 did best on Monday at 90.9% on time and worst on Wednesday at 76.9%. Each day rests on about 42 flights, so a gap of 14 points is worth noticing but could still narrow in another year.

Delay causes

Why AS 1455 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 51% of the 2,999 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.

Late-arriving aircraft
51%
Carrier
40%
National Airspace System
9%

51% 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 2,999 reported delay minutes here, that single category outweighs weather by 51 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 2,999 delay minutes reported on AS 1455.

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

Badly late arrivals are rare here: only 4.8% land an hour or more behind schedule, against 8.1% 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 1,542 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.

Every one of the 291 flights under AS 1455 in the data flew PDX to ANC. The number was not reused on any other city pair, which makes this a clean record of one route.

One caution: this is a thin sample. 291 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 1455

For a booking, read AS 1455 as 84.1% on time with 0.00% cancelled over 291 flights. Those are rates from the past twelve months, not a forecast for any particular day.
