Historical statistics for July 2025 to June 2026, not live status. For today’s AS 779, check with Alaska Airlines.

AS 779 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 an hour on average. That is a workable record, not a spotless one. That rests on 350 flights, with a median arrival 9 minutes early.

Set against the rest of the country, AS 779's record is 5 points better than the US average of 77.6%. That gap is worth roughly 45 fewer late arrivals for every thousand flights.

These figures cover 350 flights between July 2025 and June 2026. The median arrival is 9 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 779 flies

AS 779 flies LAS to PDX without a single fixed slot. Its most common scheduled departure was 18:05, used on 60 of 350 flights, with 18:20 (57 flights) and 18:31 (49 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

  • Departs 18:2057 flights16.3%
  • Departs 18:3149 flights14.0%

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 18:05 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and AS 779 runs 14 points better at 82.1%. 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 779 quarter by quarter

Quarter by quarter AS 779 held fairly steady: 77.8% in Jul–Sep 2025, 80.5% in Oct–Dec 2025, 87.5% in Jan–Mar 2026 and 82.9% in Apr–Jun 2026. A spread of 10 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Scale runs 70% to 95%. Rows with fewer than 30 flights show a dash.

By weekday, AS 779 did best on Saturday at 91.3% on time and worst on Thursday at 71.4%. 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 779 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 65% of the 3,666 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.

  • Late-arriving aircraft
    65%
  • Carrier
    18%
  • National Airspace System
    12%
  • Extreme weather
    6%

65% 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 3,666 reported delay minutes here, that single category outweighs weather by 11 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 3,666 delay minutes reported on AS 779.

Cancellations are rare at 0.86%, 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 4.9% 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.

The 763 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

Every one of the 350 flights under AS 779 in the data flew LAS 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. 350 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 779

For a booking, read AS 779 as 82.1% on time with 0.86% cancelled over 350 flights. Those are rates from the past twelve months, not a forecast for any particular day.
