These figures cover 255 flights between September 2025 and August 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.

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 2026 at 58.2%, a swing of 25 points on roughly 85 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.

- Jan–Mar 202619 flights—

Scale runs 50% to 90%. Rows with fewer than 30 flights show a dash.
By weekday, AS 36 did best on Tuesday at 93.3% on time and worst on Thursday at 64.7%. Each day rests on about 36 flights, so a gap of 29 points is worth noticing but could still narrow in another year.
Arrival by arrival
How late AS 36 runs when it is late
AS 36 often beats the schedule: 94 of 242 completed flights, 39%, arrived 15 minutes or more early. The 56 late arrivals split 16 under half an hour, 21 between 30 and 60 minutes, and 19 an hour or more.

Share of 242 completed flights by arrival against schedule.
A late pushback is often recovered here: of 69 departures that left 15 minutes late or more, 26 still arrived on time. In the other direction, 13 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at JFK.
The worst days
Worst days for AS 36
The latest arrival of the period was on 7 August 2026, 4 hours 9 minutes behind schedule; most of its delay minutes were filed as national airspace system delay. Three of the five worst days fell in August 2026.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 7 August 2026 | 4 hours 9 minutes | National Airspace System |
| 22 June 2026 | 3 hours 27 minutes | National Airspace System |
| 14 June 2026 | 3 hours 25 minutes | Extreme weather |

Delay causes
Why AS 36 runs late
National Airspace System accounts for 53% of the 3,326 delay minutes carriers reported here, and the remaining four split what is left.
- 53%National Airspace System
- 19%Late-arriving aircraft
- 16%Extreme weather
- 12%Carrier
Extreme weather accounts for 16% 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 2.7 times the usual weather exposure. The split is drawn from 3,326 delay minutes reported on AS 36.
Cancellations sit at 1.57% against a national 1.89%, which is ordinary. Diversions add another 3.53%.
Connections and routes
What a delay on this flight costs
7.9% of arrivals land an hour or more late, close to the national 8.3%, so 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 2,446 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. 255 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.
