Historical statistics for July 2025 to June 2026, not live status. For today’s AS 26, check with Alaska Airlines.

AS 26 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 roughly 50 minutes on average. That is a workable record, not a spotless one. That rests on 363 flights, with a median arrival 7 minutes early.

These figures cover 363 flights between July 2025 and June 2026. The median arrival is 7 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 26 flies

AS 26 flies SEA to JFK without a single fixed slot. Its most common scheduled departure was 07:55, used on 67 of 363 flights, with 08:05 (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 07:55 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and AS 26 runs 8 points worse at 81.5%. 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 26 quarter by quarter

AS 26 did not run the same all year. Its best quarter was Apr–Jun 2026 at 96.7% on time and its weakest Jul–Sep 2025 at 69.0%, a swing of 28 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 202689 flights77.4%

Scale runs 60% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, AS 26 ranged from 75.0% on Thursday to 85.4% on Friday. With about 52 flights behind each day, a spread of 10 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why AS 26 runs late

One category carries most of the weight here. National Airspace System accounts for 53% of the 3,053 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.

53% 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 1,632 minutes out of 3,053, against a national NAS share of 21%. The split is drawn from 3,053 delay minutes reported on AS 26.

Cancellations run at 3.86%, against 1.81% nationally. That is about one flight in 25 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 3.5% 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 2,422 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 363 flights under AS 26 in the data flew SEA 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. 363 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 26

For a booking, the cancellation rate is the figure to plan around on AS 26: 3.86% of its 363 scheduled flights did not operate. A late arrival costs roughly 50 minutes, but a cancellation costs the day, so leave a later option open.
