Historical statistics for July 2025 to June 2026, not live status. For today’s AS 24, check with Alaska Airlines.

AS 24 earns an A. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 11 points better than the national rate of 77.6%. When something does go wrong the average delay runs about an hour. That rests on 365 flights, with a median arrival 12 minutes early.

Set against the rest of the country, AS 24's record is 11 points better than the US average of 77.6%. That gap is worth roughly 105 fewer late arrivals for every thousand flights.

These figures cover 365 flights between July 2025 and June 2026. The median arrival is 12 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Schedule

When AS 24 flies

AS 24 flies SAN to JFK without a single fixed slot. Its most common scheduled departure was 07:00, used on 179 of 365 flights. 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 07:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and AS 24 runs level with that at 88.1%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Against the route

AS 24 next to SAN to JFK

Across the year

AS 24 quarter by quarter

Quarter by quarter AS 24 held fairly steady: 88.8% in Jul–Sep 2025, 85.4% in Oct–Dec 2025, 88.2% in Jan–Mar 2026 and 89.9% in Apr–Jun 2026. A spread of 5 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202592 flights88.8%
Oct–Dec 202592 flights85.4%
Jan–Mar 202690 flights88.2%
Apr–Jun 202691 flights89.9%

Scale runs 75% to 95%. Rows with fewer than 30 flights show a dash.

By weekday, AS 24 did best on Saturday at 96.1% on time and worst on Sunday at 83.0%. Each day rests on about 52 flights, so a gap of 13 points is worth noticing but could still narrow in another year.

Delay causes

Why AS 24 runs late

One category carries most of the weight here. National Airspace System accounts for 62% of the 2,384 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.

National Airspace System
62%
Extreme weather
24%
Carrier
14%

Extreme weather accounts for 24% 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 3.9 times the usual weather exposure. The split is drawn from 2,384 delay minutes reported on AS 24.

Cancellations sit at 1.10% against a national 1.81%, which is ordinary. Diversions add another 2.47%.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 2.6% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.

At 2,446 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 365 flights under AS 24 in the data flew SAN to JFK. 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. 365 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 24

For a booking, AS 24 has one of the better records a US domestic flight can show: 88.1% on time and 1.10% cancelled. That is a base rate, not a promise about any single day.
