These figures cover 342 flights between September 2025 and August 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.

Across the year
AS 779 quarter by quarter
AS 779 did not run the same all year. Its best quarter was Jan–Mar 2026 at 87.5% on time and its weakest Jul–Sep 2026 at 56.6%, a swing of 31 points on roughly 86 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 779 did best on Wednesday at 90.4% on time and worst on Friday at 57.4%. Each day rests on about 49 flights, so a gap of 33 points is worth noticing but could still narrow in another year.

The latest arrival of the period was on 15 June 2026, 4 hours 36 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on five of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 15 June 2026 | 4 hours 36 minutes | Late-arriving aircraft |
| 10 October 2025 | 4 hours 29 minutes | Late-arriving aircraft |
| 13 August 2026 | 2 hours 30 minutes | Late-arriving aircraft |
| 19 July 2026 | 2 hours 21 minutes | Late-arriving aircraft |

Delay causes
Why AS 779 runs late
Late-arriving aircraft accounts for 75% of the 3,950 delay minutes carriers reported here, and the remaining four split what is left.
- 75%Late-arriving aircraft
- 14%National Airspace System
- 7%Carrier
- 5%Extreme weather
75% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,950 reported delay minutes here, that single category outweighs weather by 17 to one. The split is drawn from 3,950 delay minutes reported on AS 779.
Cancellations are rare at 0.88%, 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
5.9% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about 55 minutes, which a normal layover absorbs.
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 342 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. 342 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
