Historical statistics for July 2025 to June 2026, not live status. For today’s AS 595, check with Alaska Airlines.

AS 595 lands a B, 6 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 45 minutes on average. That is a workable record, not a spotless one. That rests on 270 flights, with a median arrival 5 minutes early.

Set against the rest of the country, AS 595's record is 6 points better than the US average of 77.6%. That gap is worth roughly 62 fewer late arrivals for every thousand flights.

These figures cover 270 flights between July 2025 and June 2026. The median arrival is 5 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 595 flies

AS 595 flies AUS to SEA without a single fixed slot. Its most common scheduled departure was 07:15, used on 203 of 270 flights. 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 07:15 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and AS 595 runs 6 points worse at 83.8%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

AS 595 quarter by quarter

Quarter by quarter AS 595 held fairly steady: 83.5% in Jul–Sep 2025, 81.0% in Oct–Dec 2025 and 84.0% in Jan–Mar 2026. A spread of 3 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, AS 595 ranged from 78.4% on Sunday to 89.7% on Wednesday. With about 39 flights behind each day, a spread of 11 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why AS 595 runs late

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 1,927 reported delay minutes.

  • National Airspace System
    36%
  • Carrier
    30%
  • Late-arriving aircraft
    28%
  • Security
    3%
  • Extreme weather
    2%

36% 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 703 minutes out of 1,927, against a national NAS share of 21%. The split is drawn from 1,927 delay minutes reported on AS 595.

Cancellations sit at 1.48% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

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 1,770 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 two other city pairs in the data, including EWR to SFO (35) and LAX to PDX (28), but none flew often enough under AS 595 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to AUS to SEA only.

One caution: this is a thin sample. 270 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 595
