Historical statistics for July 2025 to June 2026, not live status. For today’s AS 287, check with Alaska Airlines.

AS 287 sits in the middle of the pack with a C. About seven flights in ten arrive on time by the DOT's definition, 5 points worse than the national rate of 77.6%. The late ones land an hour and a half behind schedule. That rests on 325 flights, with a median arrival 7 minutes early.

The national on-time rate over the same period is 77.6%, so AS 287 runs 5 points behind the country as a whole. Across a thousand flights that is about 48 extra late arrivals.

These figures cover 325 flights between July 2025 and June 2026. Beyond the headline rate, 14.2% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Schedule

When AS 287 flies

AS 287 flies EWR to LAX without a single fixed slot. Its most common scheduled departure was 19:29, used on 133 of 325 flights, with 19:59 (118 flights) and 19:26 (44 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 19:29 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and AS 287 runs 5 points better at 72.8%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Against the route

AS 287 next to EWR to LAX

Across its whole network Alaska Airlines managed 79.1%, which this flight trails by 6 points.

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 2025 at 63.7%, a swing of 21 points on roughly 81 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%. Rows with fewer than 30 flights show a dash.

By weekday, AS 287 ranged from 69.0% on Sunday to 76.1% on Wednesday. With about 46 flights behind each day, a spread of 7 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why AS 287 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 56% of the 7,099 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

  • Late-arriving aircraft
    56%
  • National Airspace System
    24%
  • Carrier
    13%
  • Extreme weather
    7%
  • Security
    1%

56% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 7,099 reported delay minutes here, that single category outweighs weather by 9 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 7,099 delay minutes reported on AS 287.

Cancellations sit at 2.46% against a national 1.81%, which is ordinary. Diversions add another 0.31%.

Connections and routes

What a delay on this flight costs

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 14.2% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum 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, AS 287 is a flight to put a long connection behind. 14.2% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
