These figures cover 359 flights between September 2025 and August 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.

A 10:45 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 83.9%, and AS 757 runs level with that at 84.5%. 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 Jul–Sep 2026 at 91.8% on time and its weakest Jul–Sep 2025 at 76.7%, a swing of 15 points on roughly 72 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.

- Oct–Dec 202590 flights78.4%
- Jan–Mar 202690 flights84.4%

Scale runs 70% to 95%.
By weekday, AS 757 ranged from 80.8% on Tuesday to 88.5% on Thursday. With about 51 flights behind each day, a spread of 8 points is inside normal variation, so the day you fly is not worth changing for this flight.

Share of 355 completed flights by arrival against schedule.
15 of 52 late departures made up the time and arrived on time, 29% of them. In the other direction, 18 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at LAS.
The worst days
Worst days for AS 757
The latest arrival of the period was on 8 December 2025, 5 hours 9 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 8 December 2025 | 5 hours 9 minutes | Late-arriving aircraft |
| 17 February 2026 | 4 hours 4 minutes | Carrier |
| 18 March 2026 | 3 hours | Late-arriving aircraft |
| 9 March 2026 | 2 hours 5 minutes | Late-arriving aircraft |
| 10 November 2025 | 1 hour 29 minutes | National Airspace System |
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 2,689 reported delay minutes.
- 40%Carrier
- 35%Late-arriving aircraft
- 25%National Airspace System
35% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 2,689 reported delay minutes here, that single category outweighs weather by 35 to one. The split is drawn from 2,689 delay minutes reported on AS 757.
Cancellations are rare at 0.56%, below the national 1.89% 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 3.7% land an hour or more behind schedule, against 8.3% 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.
Every one of the 359 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. 359 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 84.5% on time with 0.56% cancelled over 359 flights. Those are rates from the past twelve months, not a forecast for any particular day.
