Historical statistics for July 2025 to June 2026, not live status. For today’s AS 462, check with Alaska Airlines.

AS 462 sits in the middle of the pack with a C−. About seven flights in ten arrive on time by the DOT's definition, 9 points worse than the national rate of 77.6%. The late ones land an hour and a half behind schedule. That rests on 361 flights, with a median arrival 3 minutes early.

The national on-time rate over the same period is 77.6%, so AS 462 runs 9 points behind the country as a whole. Across a thousand flights that is about 91 extra late arrivals.

These figures cover 361 flights between July 2025 and June 2026. Beyond the headline rate, 12.9% 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 462 flies

AS 462 flies EWR to SEA without a single fixed slot. Its most common scheduled departure was 17:30, used on 133 of 361 flights, with 09:00 (40 flights) and 18:08 (38 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 17:30 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and AS 462 runs level with that at 68.5%. 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 462 next to EWR to SEA

Across its whole network Alaska Airlines managed 79.1%, which this flight trails by 11 points.

Across the year

AS 462 quarter by quarter

AS 462 did not run the same all year. Its best quarter was Apr–Jun 2026 at 82.8% on time and its weakest Oct–Dec 2025 at 58.6%, a swing of 24 points on roughly 90 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 462 did best on Friday at 76.5% on time and worst on Wednesday at 58.3%. Each day rests on about 52 flights, so a gap of 18 points is worth noticing but could still narrow in another year.

Delay causes

Why AS 462 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 52% of the 9,260 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.

Extreme weather accounts for 14% 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 2.2 times the usual weather exposure. The split is drawn from 9,260 delay minutes reported on AS 462.

Cancellations run at 3.05%, against 1.81% nationally. That is roughly 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

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 12.9% 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 2,402 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.

Every one of the 361 flights under AS 462 in the data flew EWR to SEA. 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. 361 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: 3.05% of its 361 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.
