Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with JetBlue Airways.
JetBlue on PBI to LGA carries a cancellation problem, not just a delay problem: 4.7% 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 C− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 1,115 flights. The strongest carrier on the route with a full sample, Delta Air Lines, flew 1,553 at 72.4% on time.
The national on-time rate over the same period is 77.6%, so JetBlue on PBI to LGA runs 10 points behind the country as a whole. Across a thousand flights that is about 99 extra late arrivals.

These figures cover 1,115 flights between July 2025 and June 2026. Beyond the headline rate, 16.4% 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 PBI to LGA
JetBlue flew 1,115 of the 3,199 flights on PBI to LGA, about 35% of it. Its 67.7% on time is about level with the route as a whole at 68.8%. Ranked by on-time rate it is number three of four carriers on the route, where the range runs from Delta at 72.4% to American at 57.9%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 72.4% of the time; American Airlines manages 57.9%. Sample sizes sit next to every figure, because a two-point gap across 405 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Delta Air Lines | 1,553 | 72.4% | 66 min | 4.44% | C− |
| Republic Airwaysthin sample | 126 | 67.8% | 125 min | 5.56% | C− |
| JetBlue Airways (this page) | 1,115 | 67.7% | 83 min | 4.66% | C− |
| American Airlines | 405 | 57.9% | 97 min | 4.20% | D− |
Delta Air Lines cancels 4.4% 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 40 points, against 15 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am197 flights93.7%
- 8am–11am195 flights79.1%
- 11am–2pm80 flights58.4%
- 2pm–5pm296 flights61.0%
- 5pm–8pm347 flights53.8%
- 8pm–5am—
Scale runs 45% to 100%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 53.8% on time, against 93.7% 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 347 flights scheduled in it.
Across the year
JetBlue on PBI to LGA through the year
September is the best month on the calendar at 87.5% on time. Shoulder season thins the schedule and takes the summer weather with it, and the operation gets its margin back. January was the busiest month here, with 124 flights.
Across the week, Saturday is the strongest day at 73.3% on time and Sunday the weakest at 62.9%. 10 points is a smaller lever than departure hour, but it is free.
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 28,000 reported delay minutes.
- 42%National Airspace System
- 40%Late-arriving aircraft
- 18%Carrier
- 1%Extreme weather
- 0%Security
40% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 28,000 reported delay minutes here, that single category outweighs weather by 40 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 28,238 reported delay minutes.
42% 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 12,000 minutes out of 28,000, against a national NAS share of 21%.
Cancellations run at 4.66%, against 1.81% nationally. That is about 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
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 16.4% 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 1,035 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 67.3% on time across 1,115 flights, within half a point 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 1,115 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 PBI to LGA
Put together: the delay figures matter less here than the 4.66% cancellation rate. A late arrival costs you an hour and a half; 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. 1,054 completed flights over 12 months sit behind that.
