JetBlue on LAX to JFK carries a cancellation problem, not just a delay problem: 3.5% of scheduled flights never operate, against 1.9% nationally. Of the ones that do fly, close to three flights in four arrive on time, worth a B− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 3,479 flights. The strongest carrier on the route with a full sample, Delta Air Lines, flew 3,367 at 79.4% on time.
The US average over the same twelve months is 77.3%, so there is little to separate JetBlue on LAX to JFK from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Carrier by carrier
JetBlue against every carrier on LAX to JFK
JetBlue flew 3,479 of the 10,289 flights on LAX to JFK, about 34% of it. Its 77.9% on time is about level with the route as a whole at 77.5%. Ranked by on-time rate it is number three of four carriers on the route, where the range runs from Frontier at 81.2% to American at 74.9%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The two carriers here are closely matched: 5 points 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 |
|---|---|---|---|---|---|
| Frontier Airlinesthin sample | 140 | 81.2% | 56 min | 0.71% | B+ |
| Delta Air Lines | 3,367 | 79.4% | 87 min | 2.61% | B |
| JetBlue Airways (this page) | 3,479 | 77.9% | 70 min | 3.48% | B− |
| American Airlines | 3,303 | 74.9% | 112 min | 2.66% | C |
No carrier stands out. Delta tops the table at 79.4%, 5 points clear of the bottom, which is inside the range this kind of sample moves year to year.

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 5 points between the best and worst carrier.
- 5am–8am515 flights87.7%
- 8am–11am592 flights80.8%
- 11am–2pm688 flights73.2%
- 2pm–5pm718 flights74.5%
- 5pm–8pm2 flights—
- 8pm–5am964 flights77.0%
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 73.2% on time against 87.7% for 5am–8am. 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 964 flights scheduled in it.
Across the year
JetBlue on LAX to JFK through the year
August is the worst month at 64.1% on time, 27 points below May, the best at 91.2%. 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. December was the busiest month here, with 322 flights.
Across the week, Tuesday is the strongest day at 82.5% on time and Sunday the weakest at 70.3%, a spread of 12 points.
Arrival by arrival
How late JetBlue on LAX to JFK runs when it is late
JetBlue on LAX to JFK often beats the schedule: 1,335 of 3,340 completed flights, 40%, arrived 15 minutes or more early. The 737 late arrivals split 230 under half an hour, 231 between 30 and 60 minutes, and 276 an hour or more.

Scale runs 0% to 100%.
Share of 3,340 completed flights by arrival against schedule.
212 of 777 late departures made up the time and arrived on time, 27% of them. In the other direction, 172 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 JetBlue on LAX to JFK
The latest arrival of the period was on 13 October 2025, 9 hours 53 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 13 October 2025 | 9 hours 53 minutes | Late-arriving aircraft |
| 3 August 2026 | 9 hours 48 minutes | Late-arriving aircraft |
| 14 December 2025 | 9 hours 41 minutes | Late-arriving aircraft |
| 29 May 2026 | 7 hours 56 minutes | Carrier |
| 30 October 2025 | 7 hours 49 minutes | Carrier |
Delay causes
Why JetBlue runs late on this route
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 52,000 reported delay minutes.
- 41%Late-arriving aircraft
- 34%National Airspace System
- 25%Carrier
- 0%Security
41% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 52,000 reported delay minutes here, that single category outweighs weather by 41 to one. The split is drawn from 51,917 reported delay minutes.
34% 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 17,000 minutes out of 52,000, against a national NAS share of 21%.
Cancellations run at 3.48%, against 1.89% nationally. That is about one flight in 30 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
8.3% 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 a little over an hour, which a normal layover absorbs.
At 2,475 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 is a different operation and performs like one: it runs 72.5% on time across 3,480 flights, 5 points below this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 5 points of difference.
The sample behind these figures is 3,479 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.
What to do with this
Booking JetBlue on LAX to JFK
Put together: the delay figures matter less here than the 3.48% cancellation rate. A late arrival costs you a little over an hour; a cancelled flight costs you the day. Book the 5am–8am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 3,340 completed flights over 12 months sit behind that.
