Across the year
AS 462 quarter by 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 336 completed flights by arrival against schedule.
15 of 74 late departures made up the time and arrived on time, 20% of them. In the other direction, 46 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 SEA.
The worst days
Worst days for AS 462
The latest arrival of the period was on 8 November 2025, 7 hours 12 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 |
|---|---|---|
| 8 November 2025 | 7 hours 12 minutes | Late-arriving aircraft |
| 21 July 2026 | 6 hours 41 minutes | Late-arriving aircraft |

Delay causes
Why AS 462 runs late
Late-arriving aircraft accounts for 50% of the 8,172 delay minutes carriers reported here, and the remaining four split what is left.
- 50%Late-arriving aircraft
- 28%National Airspace System
- 11%Carrier
- 9%Extreme weather
- 1%Security
50% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 8,172 reported delay minutes here, that single category outweighs weather by 5 to one. The split is drawn from 8,172 delay minutes reported on AS 462.
Cancellations run at 3.17%, against 1.89% nationally. That is about one flight in 30 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and routes
What a delay on this flight costs
12.2% 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 2,402 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.
The same number turns up on one other city pair in the data, including SEA to KTN (13), but none flew often enough under AS 462 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to EWR to SEA only.
One caution: this is a thin sample. 347 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 462
For a booking, the cancellation rate is the figure to plan around on AS 462: 3.17% of its 347 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
