Historical statistics for July 2025 to June 2026, not live status. For today’s AS 18, check with Alaska Airlines.

AS 18 lands a B, 5 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by about 50 minutes on average. That is a workable record, not a spotless one. That rests on 364 flights, with a median arrival 6 minutes early.

Set against the rest of the country, AS 18's record is 5 points better than the US average of 77.6%. That gap is worth roughly 52 fewer late arrivals for every thousand flights.

These figures cover 364 flights between July 2025 and June 2026. The median arrival is 6 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 18 flies

AS 18 flies PDX to JFK without a single fixed slot. Its most common scheduled departure was 07:05, used on 97 of 364 flights, with 07:00 (80 flights) and 07:20 (50 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 07:05 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and AS 18 runs 7 points worse at 82.8%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

AS 18 quarter by quarter

AS 18 did not run the same all year. Its best quarter was Oct–Dec 2025 at 87.8% on time and its weakest Jul–Sep 2025 at 73.6%, a swing of 14 points on roughly 91 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.

Jan–Mar 202690 flights83.9%

By weekday, AS 18 did best on Saturday at 88.2% on time and worst on Thursday at 75.5%. Each day rests on about 52 flights, so a gap of 13 points is worth noticing but could still narrow in another year.

Delay causes

Why AS 18 runs late

One category carries most of the weight here. National Airspace System accounts for 85% of the 3,012 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.

85% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 2,548 minutes out of 3,012, against a national NAS share of 21%. The split is drawn from 3,012 delay minutes reported on AS 18.

Cancellations sit at 1.92% against a national 1.81%, which is ordinary. Diversions add another 0.82%.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 3.4% 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 2,454 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 364 flights under AS 18 in the data flew PDX to JFK. 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. 364 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.
