Every carrier on SAN to JFK, 2,417 flights
These figures cover 724 flights between September 2025 and August 2026. The median arrival is 16 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.

Carrier by carrier
JetBlue against every carrier on SAN to JFK
JetBlue flew 724 of the 2,417 flights on SAN to JFK, about 30% of it. Its 81.7% on time is about level with the route as a whole at 82.6%. Ranked by on-time rate it is last of three carriers on the route, where the range runs from Alaska at 83.4% to JetBlue at 81.7%.
The two carriers here are closely matched: half a point separate the best from the worst. At that spread, schedule and price are better tie-breakers than reliability. Sample sizes are shown so you can see which rows are worth weighing.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Alaska Airlines | 647 | 83.4% | 57 min | 1.70% | B |
| Delta Air Lines | 1,046 | 82.8% | 111 min | 3.35% | B− |
| JetBlue Airways (this page) | 724 | 81.7% | 107 min | 4.56% | B− |
Delta Air Lines cancels 3.4% of what it schedules here, the highest in the table. A cancelled flight never appears in an on-time rate, so read that column alongside the punctuality one rather than after it.

Departure window
When JetBlue runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 15 points, against half a point between the best and worst carrier.
- 5am–8am—
- 8am–11am109 flights87.7%
- 11am–2pm155 flights72.7%
- 2pm–5pm101 flights73.2%
- 5pm–8pm—
- 8pm–5am359 flights86.0%
Scale runs 65% to 95%. Rows with fewer than 30 flights show a dash.
The weak window here is the middle of the day, not the evening: 11am–2pm runs 72.7% on time against 87.7% for 8am–11am. That shape usually means a departure bank rather than an accumulating delay, so the recovery later in the afternoon is real rather than noise. The 8pm–5am window is the busiest, with 359 flights scheduled in it.
Across the year
JetBlue on SAN to JFK through the year
July is the worst month at 64.2% on time, 26 points below May, the best at 90.2%. Summer afternoon convection and peak-season schedules land on the same weeks every year, so this is a pattern you can book around rather than a run of bad luck. November was the busiest month here, with 63 flights.
Across the week, Friday is the strongest day at 88.2% on time and Sunday the weakest at 71.7%, a spread of 17 points.

The worst days
Worst days for JetBlue on SAN to JFK
The latest arrival of the period was on 16 February 2026, 22 hours 59 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 16 February 2026 | 22 hours 59 minutes | Carrier |
| 26 January 2026 | 22 hours 54 minutes | Carrier |
| 17 September 2025 | 14 hours 47 minutes | Late-arriving aircraft |
| 13 March 2026 | 13 hours 50 minutes | Carrier |
| 28 February 2026 | 6 hours 52 minutes | Late-arriving aircraft |
Delay causes
Why JetBlue runs late on this route
Carrier accounts for 43% of the 13,000 delay minutes carriers reported here, and the remaining four split what is left.
- 43%Carrier
- 33%Late-arriving aircraft
- 22%National Airspace System
- 2%Extreme weather
The largest share of delay minutes, 43%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 5,804 of the 13,000 delay minutes reported here. The split is drawn from 13,430 reported delay minutes.
The practical consequence: the 8am–11am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 87.7% on time here.
Cancellations run at 4.56%, against 1.89% nationally. That is roughly one flight in twenty 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 stage length
What a delay here costs
7.7% 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 close to two hours, 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 return leg runs 83.2% on time across 724 flights, within 2 points of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
One caution: this is a thin sample. 724 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 JetBlue on SAN to JFK
Put together: the delay figures matter less here than the 4.56% cancellation rate. A late arrival costs you close to two hours; a cancelled flight costs you the day. Book the 8am–11am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 688 completed flights over 12 months sit behind that.
