Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with JetBlue Airways.
JetBlue on FLL to LGA carries a cancellation problem, not just a delay problem: 3.4% of scheduled flights never operate, against 1.8% nationally. Of the ones that do fly, about two flights in three arrive on time, worth a D− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 1,598 flights. The strongest carrier on the route with a full sample, Delta Air Lines, flew 1,598 at 72.7% on time.
Delta Air Lines is the most reliable of the three carriers covered here at 72.7% on time across 1,598 flights.

These figures cover 1,598 flights between July 2025 and June 2026. Beyond the headline rate, 15.0% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Carrier by carrier
JetBlue against every carrier on FLL to LGA
JetBlue flew 1,598 of the 4,653 flights on FLL to LGA, about 34% of it. Its 63.5% on time is 3 points worse than the route as a whole, which runs 66.3%. Ranked by on-time rate it is number three of four carriers on the route, where the range runs from Delta at 72.7% to American at 55.5%.
The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 72.7% of the time; American Airlines manages 55.5%. Sample sizes sit next to every figure, because a two-point gap across 481 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Delta Air Lines | 1,598 | 72.7% | 68 min | 3.69% | C− |
| Spirit Airlines | 976 | 65.9% | 77 min | 6.45% | C− |
| JetBlue Airways (this page) | 1,598 | 63.5% | 68 min | 3.44% | D− |
| American Airlines | 481 | 55.5% | 97 min | 4.37% | D− |
Spirit Airlines cancels 6.5% 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 41 points, against 17 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am170 flights90.7%
- 8am–11am328 flights81.0%
- 11am–2pm305 flights59.4%
- 2pm–5pm23 flights—
- 5pm–8pm453 flights49.4%
- 8pm–5am319 flights55.3%
Scale runs 40% to 95%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 49.4% on time, against 90.7% for the 5am–8am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 5pm–8pm window is the busiest, with 453 flights scheduled in it.
Across the year
JetBlue on FLL to LGA through the year
September is the best month on the calendar at 78.6% on time. Shoulder season thins the schedule and takes the summer weather with it, and the operation gets its margin back. May was the busiest month here, with 174 flights.
Across the week, Saturday is the strongest day at 72.9% on time and Sunday the weakest at 55.3%. 18 points is a smaller lever than departure hour, but it is free.
Delay causes
Why JetBlue runs late on this route
One category carries most of the weight here. National Airspace System accounts for 45% of the 38,000 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

- 29%Late-arriving aircraft
- 24%Carrier
- 1%Extreme weather
- 0%Security
45% 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 38,000, against a national NAS share of 21%. The split is drawn from 37,958 reported delay minutes.
The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 90.7% on time here.
Cancellations run at 3.44%, against 1.81% 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
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 15.0% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.
The 1,076 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
The return leg runs 65.3% on time across 1,596 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.
The sample behind these figures is 1,598 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 FLL to LGA
Put together: the delay figures matter less here than the 3.44% 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. 1,529 completed flights over 12 months sit behind that.
