JetBlue on EWR to PBI sits in the middle of the pack with a C−. Close to three flights in four arrive on time by the DOT's definition, 4 points worse than the national rate of 77.3%. The late ones land about an hour behind schedule. That rests on 659 flights, with a median arrival 5 minutes early.

The US average over the same twelve months is 77.3%, so there is little to separate JetBlue on EWR to PBI 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 EWR to PBI

JetBlue flew 659 of the 3,395 flights on EWR to PBI, about 19% of it. Its 73.8% on time is 4 points worse than the route as a whole, which runs 77.5%. Ranked by on-time rate it is number two of three carriers on the route, where the range runs from United at 79.4% 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 18 points, against half a point between the best and worst carrier.

5am–8am127 flights81.5%
8am–11am172 flights77.1%
11am–2pm68 flights63.6%
2pm–5pm149 flights64.5%
5pm–8pm108 flights77.1%
8pm–5am35 flights76.5%

Scale runs 55% to 85%.

The weak window here is the middle of the day, not the evening: 11am–2pm runs 63.6% 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 172 flights scheduled in it.

Across the year

JetBlue on EWR to PBI through the year

Darker means more delays. Figures are on-time percentages.May best, December worst

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, Wednesday is the strongest day at 80.7% on time and Sunday the weakest at 65.6%, a spread of 15 points.

Arrival by arrival

How late JetBlue on EWR to PBI runs when it is late

JetBlue on EWR to PBI often beats the schedule: 194 of 633 completed flights, 31%, arrived 15 minutes or more early. The 166 late arrivals split 61 under half an hour, 51 between 30 and 60 minutes, and 54 an hour or more.

Share of 633 completed flights by arrival against schedule.

30 of 135 late departures made up the time and arrived on time, 22% of them. In the other direction, 61 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 PBI.

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 10,000 reported delay minutes.

National Airspace System
39%
Late-arriving aircraft
30%
Carrier
23%
Extreme weather
8%
Security
0%

39% 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 4,055 minutes out of 10,000, against a national NAS share of 21%. The split is drawn from 10,350 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 81.5% on time here.

Cancellations run at 3.49%, 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

8.5% 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 about an hour, which a normal layover absorbs.

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.

The return leg runs 71.5% on time across 655 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. 659 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: the delay figures matter less here than the 3.49% cancellation rate. A late arrival costs you about 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. 633 completed flights over 12 months sit behind that.
