Historical statistics for July 2025 to June 2026, not live status. For today’s AS 353, check with Alaska Airlines.

AS 353 earns an A+. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 11 points better than the national rate of 77.6%. When something does go wrong the average delay runs roughly 40 minutes. That rests on 362 flights, with a median arrival 12 minutes early.

Set against the rest of the country, AS 353's record is 11 points better than the US average of 77.6%. That gap is worth roughly 113 fewer late arrivals for every thousand flights.

These figures cover 362 flights between July 2025 and June 2026. The median arrival is 12 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 353 flies

AS 353 flies PDX to OGG without a single fixed slot. Its most common scheduled departure was 17:47, used on 67 of 362 flights, with 17:46 (50 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 17:47 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and AS 353 runs 21 points better at 88.9%. 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 353 quarter by quarter

AS 353 did not run the same all year. Its best quarter was Apr–Jun 2026 at 94.5% on time and its weakest Jan–Mar 2026 at 80.7%, 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.

By weekday, AS 353 did best on Wednesday at 96.1% on time and worst on Friday at 80.4%. Each day rests on about 52 flights, so a gap of 16 points is worth noticing but could still narrow in another year.

Delay causes

Why AS 353 runs late

One category carries most of the weight here. Carrier accounts for 44% of the 1,663 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.

  • Carrier
    44%
  • National Airspace System
    21%
  • Extreme weather
    18%
  • Late-arriving aircraft
    17%

Extreme weather accounts for 18% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.9 times the usual weather exposure. The split is drawn from 1,663 delay minutes reported on AS 353.

Cancellations are rare at 0.55%, below the national 1.81% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 2.2% 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 2,561 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 362 flights under AS 353 in the data flew PDX to OGG. 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. 362 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 353

For a booking, AS 353 has one of the better records a US domestic flight can show: 88.9% on time and 0.55% cancelled. That is a base rate, not a promise about any single day.
