Historical statistics for July 2025 to June 2026, not live status. For today’s AS 325, check with Alaska Airlines.

AS 325 sits in the middle of the pack with a C. About seven flights in ten arrive on time by the DOT's definition, 8 points worse than the national rate of 77.6%. The late ones land about 50 minutes behind schedule. That rests on 351 flights, with a median arrival 2 minutes late.

The national on-time rate over the same period is 77.6%, so AS 325 runs 8 points behind the country as a whole. Across a thousand flights that is about 81 extra late arrivals.

These figures cover 351 flights between July 2025 and June 2026. On-time means an arrival less than 15 minutes after the scheduled gate time, the same threshold the Department of Transportation uses in its own reports. Cancelled and diverted flights are excluded from the on-time rate and counted separately, which is why the cancellation column matters on its own.

Schedule

When AS 325 flies

AS 325 flies ORD to PDX without a single fixed slot. Its most common scheduled departure was 14:07, used on 78 of 351 flights, with 14:03 (49 flights) and 14:05 (42 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 14:07 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and AS 325 runs 3 points worse at 69.5%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

AS 325 quarter by quarter

AS 325 did not run the same all year. Its best quarter was Jan–Mar 2026 at 79.2% on time and its weakest Oct–Dec 2025 at 51.7%, a swing of 28 points on roughly 88 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 325 did best on Saturday at 75.6% on time and worst on Wednesday at 56.5%. Each day rests on about 50 flights, so a gap of 19 points is worth noticing but could still narrow in another year.

Delay causes

Why AS 325 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 58% of the 5,319 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.

58% 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 5,319 reported delay minutes here, that single category outweighs weather by 39 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 5,319 delay minutes reported on AS 325.

Cancellations sit at 1.14% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

6.9% 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 50 minutes, which a normal layover absorbs.

At 1,739 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 351 flights under AS 325 in the data flew ORD to PDX. 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. 351 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.

Booking AS 325
