These figures cover 721 flights between July 2025 and June 2026. Beyond the headline rate, 9.2% 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 EWR to PBI
JetBlue flew 721 of the 3,611 flights on EWR to PBI, about 20% of it. Its 73.3% on time is 4 points worse than the route as a whole, which runs 77.1%. Ranked by on-time rate it is number two of three carriers on the route, where the range runs from United at 79.1% to Spirit at 51.5%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

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 16 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am127 flights81.5%
- 8am–11am141 flights78.1%
- 11am–2pm130 flights65.1%
- 2pm–5pm126 flights68.4%
- 5pm–8pm100 flights78.8%
- 8pm–5am97 flights66.7%
Scale runs 55% to 85%. 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 65.1% on time against 81.5% 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 8am–11am window is the busiest, with 141 flights scheduled in it.
Across the year
JetBlue on EWR to PBI through the year
December is the weak month at 58.7% on time, against 90.6% in May. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. December was the busiest month here, with 78 flights.
Across the week, Tuesday is the strongest day at 82.3% on time and Sunday the weakest at 66.7%. 16 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 13,000 reported delay minutes.
- 34%Late-arriving aircraft
- 30%National Airspace System
- 28%Carrier
- 8%Extreme weather
- 0%Security
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 81.5% on time here. The split is drawn from 12,770 reported delay minutes.
No single cause dominates. late-arriving aircraft at 34%, national airspace system at 30% and carrier at 28% split the 13,000 reported delay minutes between them. An even spread like this usually means the operation is running close to its designed capacity with no one obvious weak point, and it is the hardest pattern for a traveller to route around.
Cancellations run at 2.77%, against 1.81% nationally. That is roughly one flight in 40 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. 9.2% 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 1,024 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 70.9% on time across 719 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. 721 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 EWR to PBI
Put together: treat all of this as provisional. 721 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 73.3% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 696 completed flights over 12 months sit behind that.
