Across the year
AS 290 quarter by quarter
AS 290 did not run the same all year. Its best quarter was Jul–Sep 2025 at 83.3% on time and its weakest Jul–Sep 2026 at 64.3%, a swing of 19 points on roughly 65 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.

Share of 319 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 53 departures that left 15 minutes late or more, only 6 made it up before arrival. In the other direction, 44 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 PDX.

Delay causes
Why AS 290 runs late
National Airspace System accounts for 45% of the 6,702 delay minutes carriers reported here, and the remaining four split what is left.

- 18%Extreme weather

- 0%Security
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 6,702 delay minutes reported on AS 290.
Cancellations sit at 1.54% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
10.0% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
At 2,434 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 324 flights under AS 290 in the data flew EWR 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. 324 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
