AS 1396 earns an A. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 8 points better than the national rate of 77.6%. When something does go wrong the average delay runs roughly 45 minutes. That rests on 347 flights, with a median arrival 8 minutes early.

Set against the rest of the country, AS 1396's record is 8 points better than the US average of 77.6%. That gap is worth roughly 77 fewer late arrivals for every thousand flights.

These figures cover 347 flights between July 2025 and June 2026. The median arrival is 8 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 1396 flies

AS 1396 flies AUS to PDX without a single fixed slot. Its most common scheduled departure was 18:00, used on 50 of 347 flights, with 17:46 (46 flights) and 17:50 (45 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 18:00 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and AS 1396 runs 17 points better at 85.3%. 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 1396 quarter by quarter

AS 1396 did not run the same all year. Its best quarter was Apr–Jun 2026 at 91.1% on time and its weakest Oct–Dec 2025 at 77.0%, a swing of 14 points on roughly 87 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 1396 did best on Tuesday at 97.8% on time and worst on Thursday at 78.0%. Each day rests on about 50 flights, so a gap of 20 points is worth noticing but could still narrow in another year.

Delay causes

Why AS 1396 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 68% of the 2,308 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.

  • National Airspace System
    19%
  • Carrier
    8%
  • Extreme weather
    3%
  • Security
    1%

68% 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 2,308 reported delay minutes here, that single category outweighs weather by 20 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 2,308 delay minutes reported on AS 1396.

Cancellations sit at 1.15% against a national 1.81%, which is ordinary. Diversions add another 0.86%.

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 1,715 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 347 flights under AS 1396 in the data flew AUS 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. 347 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 1396

For a booking, AS 1396 has one of the better records a US domestic flight can show: 85.3% on time and 1.15% cancelled. That is a base rate, not a promise about any single day.
