Historical statistics for July 2025 to June 2026, not live status. For today’s AS 19, check with Alaska Airlines.

AS 19 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 about an hour behind schedule. That rests on 363 flights, with a median arrival 1 minute early.

The national on-time rate over the same period is 77.6%, so AS 19 runs 5 points behind the country as a whole. Across a thousand flights that is about 54 extra late arrivals.

These figures cover 363 flights between July 2025 and June 2026. Beyond the headline rate, 8.5% 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 19 flies

AS 19 flies JFK to PDX without a single fixed slot. Its most common scheduled departure was 17:29, used on 153 of 363 flights, with 17:28 (55 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.

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

A 17:29 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and AS 19 runs 4 points better at 72.2%. 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 19 next to JFK to PDX

Every carrier on JFK to PDX combined arrived on time 72.1% of the time across 914 flights, so AS 19 is about level with it. Across its whole network Alaska Airlines managed 79.1%, which this flight trails by 7 points.

Across the year

AS 19 quarter by quarter

AS 19 did not run the same all year. Its best quarter was Apr–Jun 2026 at 86.7% on time and its weakest Oct–Dec 2025 at 57.3%, a swing of 29 points on roughly 91 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 19 did best on Saturday at 80.0% on time and worst on Thursday at 57.1%. Each day rests on about 52 flights, so a gap of 23 points is worth noticing but could still narrow in another year.

Delay causes

Why AS 19 runs late

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 6,220 reported delay minutes.

National Airspace System
37%
Late-arriving aircraft
34%
Carrier
17%
Extreme weather
12%
Security
1%

Extreme weather accounts for 12% 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 1.9 times the usual weather exposure. The split is drawn from 6,220 delay minutes reported on AS 19.

Cancellations run at 2.75%, against 1.81% nationally. That is roughly one flight in 40 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

8.5% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.

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.

Every one of the 363 flights under AS 19 in the data flew JFK to PDX. 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. 363 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 19

For a booking, the cancellation rate is the figure to plan around on AS 19: 2.75% of its 363 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
