Historical statistics for July 2025 to June 2026, not live status. For today’s AS 757, check with Alaska Airlines.

AS 757 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 roughly 45 minutes on average. That is a workable record, not a spotless one. That rests on 352 flights, with a median arrival right on schedule.

Set against the rest of the country, AS 757's record is 5 points better than the US average of 77.6%. That gap is worth roughly 54 fewer late arrivals for every thousand flights.

These figures cover 352 flights between July 2025 and June 2026. On-time means an arrival less than 15 minutes after the scheduled gate time, the same threshold the Department of Transportation uses in its own reports. Cancelled and diverted flights are excluded from the on-time rate and counted separately, which is why the cancellation column matters on its own.

Schedule

When AS 757 flies

AS 757 flies PDX to LAS without a single fixed slot. Its most common scheduled departure was 10:45, used on 76 of 352 flights, with 10:38 (54 flights) and 10:50 (48 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 10:45 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and AS 757 runs level with that at 83.0%. 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 757 quarter by quarter

AS 757 did not run the same all year. Its best quarter was Apr–Jun 2026 at 88.4% on time and its weakest Oct–Dec 2025 at 78.4%, a swing of 10 points on roughly 88 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.

Jul–Sep 202585 flights81.0%
Oct–Dec 202590 flights78.4%
Jan–Mar 202690 flights84.4%
Apr–Jun 202687 flights88.4%

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

By weekday, AS 757 ranged from 76.9% on Monday to 86.8% on Saturday. With about 50 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 757 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 2,759 reported delay minutes.

Carrier
42%
Late-arriving aircraft
32%
National Airspace System
26%

The largest share of delay minutes, 42%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 1,147 of the 2,759 delay minutes reported here. The split is drawn from 2,759 delay minutes reported on AS 757.

Cancellations are rare at 0.85%, 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 4.0% 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 352 flights under AS 757 in the data flew PDX to LAS. 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. 352 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 757

For a booking, read AS 757 as 83.0% on time with 0.85% cancelled over 352 flights. Those are rates from the past twelve months, not a forecast for any particular day.
