These figures cover 291 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 08:30 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 83.9%, and AS 265 runs 7 points worse at 76.6%. 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 265 quarter by quarter
AS 265 did not run the same all year. Its best quarter was Jan–Mar 2026 at 81.8% on time and its weakest Jul–Sep 2026 at 66.7%, a swing of 15 points on roughly 73 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 265 did best on Saturday at 87.5% on time and worst on Sunday at 65.8%. Each day rests on about 42 flights, so a gap of 22 points is worth noticing but could still narrow in another year.

Share of 286 completed flights by arrival against schedule.
9 of 42 late departures made up the time and arrived on time, 21% of them. In the other direction, 34 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 ORD.
The worst days
Worst days for AS 265
The latest arrival of the period was on 17 January 2026, 3 hours 4 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). On three of the five worst days the largest share was filed as national airspace system delay.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 17 January 2026 | 3 hours 4 minutes | Carrier |
| 30 November 2025 | 2 hours 59 minutes | National Airspace System |
| 2 July 2026 | 2 hours 53 minutes | Carrier |

Delay causes
Why AS 265 runs late
National Airspace System accounts for 63% of the 3,372 delay minutes carriers reported here, and the remaining four split what is left.
- 63%National Airspace System
- 26%Carrier
- 6%Late-arriving aircraft
- 5%Extreme weather
63% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 2,138 minutes out of 3,372, against a national NAS share of 21%. The split is drawn from 3,372 delay minutes reported on AS 265.
Cancellations sit at 1.03% against a national 1.89%, which is ordinary. Diversions add another 0.69%.
Connections and routes
What a delay on this flight costs
6.6% 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 50 minutes, which a normal layover absorbs.
At 1,721 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 291 flights under AS 265 in the data flew SEA to ORD. 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. 291 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.
