Historical statistics for July 2025 to June 2026, not live status. For today’s AS 36, check with Alaska Airlines.

AS 36 lands a B, level with the national rate of 77.6%. Roughly one flight in five arrives 15 minutes late or worse, and those flights are late by roughly 50 minutes on average. That is a workable record, not a spotless one. That rests on 258 flights, with a median arrival 7 minutes early.

These figures cover 258 flights between July 2025 and June 2026. The median arrival is 7 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 36 flies

AS 36 flies SAN to JFK without a single fixed slot. Its most common scheduled departure was 21:59, used on 60 of 258 flights, with 21:25 (60 flights) and 21:56 (50 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 21:59 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and AS 36 runs 8 points better at 78.0%. 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 36 next to SAN to JFK

Every carrier on SAN to JFK combined arrived on time 83.8% of the time across 2,413 flights, so AS 36 is 6 points behind it. Alaska flew 650 flights on the same city pair under all its flight numbers, including this one, and those ran 83.7% on time. Across its whole network Alaska Airlines managed 79.1%, close to this flight's figure.

Across the year

AS 36 quarter by quarter

AS 36 did not run the same all year. Its best quarter was Oct–Dec 2025 at 82.8% on time and its weakest Jul–Sep 2025 at 72.4%, a swing of 10 points on roughly 86 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 65% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, AS 36 did best on Tuesday at 90.9% on time and worst on Saturday at 64.7%. Each day rests on about 37 flights, so a gap of 26 points is worth noticing but could still narrow in another year.

Delay causes

Why AS 36 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 2,789 reported delay minutes.

National Airspace System
40%
Late-arriving aircraft
31%
Carrier
18%
Extreme weather
11%

40% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 1,128 minutes out of 2,789, against a national NAS share of 21%. The split is drawn from 2,789 delay minutes reported on AS 36.

Cancellations sit at 1.94% against a national 1.81%, which is ordinary. Diversions add another 2.71%.

Connections and routes

What a delay on this flight costs

6.1% 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 roughly 50 minutes, which a normal layover absorbs.

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.

The same number turns up on one other city pair in the data, including SEA to JFK (1), but none flew often enough under AS 36 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SAN to JFK only.

One caution: this is a thin sample. 258 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 36

For a booking, AS 36 is one of the weaker ways to fly SAN to JFK: 6 points below the route as a whole. If the schedule allows, compare it with the other departures listed on the route page before settling on this one.
