A 19:29 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.0%, and AS 287 runs 5 points better at 73.2%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year

AS 287 quarter by quarter

AS 287 did not run the same all year. Its best quarter was Apr–Jun 2026 at 84.6% on time and its weakest Jul–Sep 2026 at 62.1%, a swing of 22 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.

Scale runs 55% to 90%.

By weekday, AS 287 ranged from 68.2% on Friday to 78.7% on Monday. With about 46 flights behind each day, a spread of 11 points is inside normal variation, so the day you fly is not worth changing for this flight.

Share of 313 completed flights by arrival against schedule.

28 of 94 late departures made up the time and arrived on time, 30% 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 LAX.

Delay causes

Why AS 287 runs late

Late-arriving aircraft accounts for 56% of the 7,077 delay minutes carriers reported here, and the remaining four split what is left.

  • Late-arriving aircraft

  • National Airspace System
    22%
  • Carrier

  • Extreme weather

  • Security

56% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 7,077 reported delay minutes here, that single category outweighs weather by 6 to one. The split is drawn from 7,077 delay minutes reported on AS 287.

Cancellations run at 3.38%, 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

12.5% 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 2,454 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 BZN (36), but none flew often enough under AS 287 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to EWR to LAX only.

One caution: this is a thin sample. 325 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 287

For a booking, the cancellation rate is the figure to plan around on AS 287: 3.38% of its 325 scheduled flights did not operate. A late arrival costs an hour and a half, but a cancellation costs the day, so leave a later option open.
