AS36
San Diego (SAN) to New York (JFK) · scheduled 10:40 PM – 7:00 AM
How AS36 performs
876 operations, July 2023 – July 2026.
AS36 arrived on time 84.1% of the time, against 80.0% for all SAN → JFK flights, so this departure is 4.1 percentage points better than the route as a whole. Against Alaska Airlines’ own flights on this route it is 4.9 points better.
AS36’s scheduled departure has moved during the period FlyerIntel has on file: it typically left around 10:45 PM earlier on, and around 10:00 PM more recently — a 45-minute shift, not the few minutes of day-to-day rounding every published schedule carries. Confirm the current departure time before booking around an older listing.

What stands out
How AS36 compares to other flight numbers, not just to itself.
Which day you fly matters unusually much here, a wider weekday spread than 94% of 1,710 comparable flight numbers.
94.1% on time on a typical Tuesday, against 75.0% on a Thursday.

Why AS36 runs late
Where US DOT attributed the delay minutes on this flight.
airspace and airport capacity, including weather-driven flow control
the inbound aircraft was late, so this flight started late
crew, maintenance, boarding and fueling, all within the carrier’s control
weather severe enough to stop this flight specifically

Does a late aircraft delay this flight?
How often the plane that flies AS36 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, AS36 pushed back an average of 13 minutes late; when it came in on time or early, an average of 0 minutes early.
Each departure is matched to the flight the same aircraft flew into SAN just before it, using the tail number in the DOT file, 819 of 866 departures in all. A departure is left out when that flight is unknown, was cancelled or diverted, or the aircraft had sat for more than 12 hours. A flight the airline cancelled never left and is not in the count, and one flown by a substitute aircraft is matched to the aircraft that flew it, not to the one first planned.
Against the network at the same turn length
| Share of departures | Inbound landed 15+ late | Left 15+ late after a late inbound | Left 15+ late after an on-time inbound |
|---|---|---|---|
| AS36 | 23% | 40% | 8% |
| Network, same turn | 23% | 40% | 9% |
The schedule leaves a long gap on the ground, which gives a late aircraft room to catch up before this flight pushes back.
The network row is every flight with a scheduled turn of 90 minutes to 3 hours. How often AS36’s aircraft landed 15 or more minutes late is about the same as the network’s and, once the aircraft was late, how often AS36 left 15 or more minutes late is about the same as the network’s.

From pushback to gate
When it leaves SAN late, does that still matter by the time it reaches JFK?
AS36 pushes back an average of 4.1 minutes late and reaches the gate at JFK an average of 3.9 minutes early. The 8.0 minutes between those two figures are slack the published schedule already carries, which is why a late pushback on this flight does not reliably become a late arrival. It spends 22.0 minutes on the taxiways at SAN, 1.3 minutes longer than a typical SAN departure in the same hour.
On arrival at JFK, AS36 spends 10.9 min taxiing from touchdown to the gate — ground time a connecting passenger sits through before they can even leave the aircraft, on top of however late the flight itself ran. That is about what any arrival at JFK spends on the ground before reaching the gate.
Departure delay is averaged over every pushback and arrival delay over every completed arrival, so the two counts differ by the flights that never reached JFK. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 11,726 departures from SAN scheduled in the clock hour AS36 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at JFK (351,546 flights), not just AS36’s own. More on taxi time.

The hour it leaves SAN
Part of any flight’s record belongs to the clock rather than to the flight. AS36 has one departure time, so this is what that time is worth.
On-time arrival rate. 11,726 departures from SAN are scheduled in the 10 PM–11 PM hour over the period, against 297,668 across the whole day.
AS36 is scheduled out of SAN at 10:40 PM, in the 10 PM–11 PM bank. Departures from SAN in that hour arrive on time 87.6% of the time against 77.9% across the airport’s whole day — the slot alone is worth 9.7 points better before anything about this particular flight is considered.
The two airport figures cover every departure from SAN to every destination, so they describe the slot rather than this journey — the like-for-like comparison against the route is above. Hours are scheduled local, and a number whose schedule moved between banks inside the period has no single hour and is not described here at all. Why the hour matters.

By day of week
Does AS36 run worse on particular days?
Tuesday is historically the most reliable day and Thursday the least, a gap of 19.1 percentage points.

Other routes AS36 has flown
A flight number is a slot in a schedule, and carriers reassign it. These are the other city pairs this number served in the analysis period.
| Route | Operated | Flights | On time |
|---|---|---|---|
| ADQ→ANC Kodiak to Anchorage | May 13, 2026 | 1 | — |
| SEA→JFK Seattle to New York | January 7, 2026 | 1 | — |
| JFK→SFO New York to San Francisco | February 13, 2025 – March 18, 2025 | 19 | — |
Because the same number has served different journeys, the statistics above describe only the route AS36 currently operates. Blending them would produce an average of two different flights.

Same airports, same journey, different odds of arriving on time.
| Flight | Airline | On time | Median arrival | Operations |
|---|---|---|---|---|
| AS36 this flight | Alaska Airlines | 84.1% | 9 min early | 876 |

Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. AS36 is placed in the same ordering rather than left out of it; the rows around it are the most punctual departures on the route, not all of them, so this is a comparison and not a rank. Schedules change; confirm the departure still operates before booking around this.
Data and methodology
Calculated by FlyerIntel from 876 records of AS36 operating SAN → JFK, published by the US DOT Bureau of Transportation Statistics. A flight counts as delayed when it arrives 15 or more minutes after schedule. Cancelled and diverted flights are excluded from the on-time rate and reported separately. Flight numbers are resolved as carrier plus number plus route, because the same number serves different routes over time.
