Historical statistics for July 2025 to June 2026, not live status. For today’s AS 783, check with Alaska Airlines.

AS 783 lands a B+, 4 points better than the national rate of 77.6%. Roughly one flight in five arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That is a workable record, not a spotless one. That rests on 286 flights, with a median arrival 8 minutes early.

Set against the rest of the country, AS 783's record is 4 points better than the US average of 77.6%. That gap is worth roughly 42 fewer late arrivals for every thousand flights.

These figures cover 286 flights between July 2025 and June 2026. Beyond the headline rate, 8.1% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Schedule

When AS 783 flies

AS 783 flies ATL to PDX without a single fixed slot. Its most common scheduled departure was 18:11, used on 68 of 286 flights, with 18:21 (45 flights) and 16:33 (30 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 18:11 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and AS 783 runs 14 points better at 81.8%. 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 783 quarter by quarter

Quarter by quarter AS 783 held fairly steady: 81.5% in Jul–Sep 2025, 76.9% in Oct–Dec 2025 and 84.5% in Apr–Jun 2026. A spread of 8 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, AS 783 did best on Saturday at 88.2% on time and worst on Wednesday at 73.8%. Each day rests on about 41 flights, so a gap of 14 points is worth noticing but could still narrow in another year.

Delay causes

Why AS 783 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 50% of the 3,897 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.

50% 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 3,897 reported delay minutes here, that single category outweighs weather by 15 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 3,897 delay minutes reported on AS 783.

Cancellations are rare at 0.35%, 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

8.1% 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 a little over an hour, which a normal layover absorbs.

At 2,172 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 DEN to SEA (34), but none flew often enough under AS 783 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ATL to PDX only.

One caution: this is a thin sample. 286 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 783

For a booking, read AS 783 as 81.8% on time with 0.35% cancelled over 286 flights. Those are rates from the past twelve months, not a forecast for any particular day.
