JetBlue on PBI to JFK carries a cancellation problem, not just a delay problem: 4.1% 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 1,384 flights, with a median arrival 6 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate JetBlue on PBI to JFK from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

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 29 points, against half a point between the best and worst carrier.
- 5am–8am317 flights92.8%
- 8am–11am344 flights84.3%
- 11am–2pm225 flights70.8%
- 2pm–5pm166 flights68.6%

Scale runs 55% to 100%.
The 5pm–8pm window is where this operation falls apart: 64.1% on time, against 92.8% 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 8am–11am window is the busiest, with 344 flights scheduled in it.
Across the year
JetBlue on PBI to JFK through the year
January is the weak month at 66.2% on time, against 93.1% in September. 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. April was the busiest month here, with 160 flights.
Across the week, Tuesday is the strongest day at 84.9% on time and Sunday the weakest at 69.0%, a spread of 16 points.

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

The worst days
Worst days for JetBlue on PBI to JFK
The latest arrival of the period was on 14 March 2026, 16 hours 4 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 14 March 2026 | 16 hours 4 minutes | Carrier |
| 19 July 2026 | 12 hours 1 minute | Late-arriving aircraft |
| 23 December 2025 | 8 hours 48 minutes | Carrier |
| 8 April 2026 | 8 hours 24 minutes | Late-arriving aircraft |
| 9 February 2026 | 7 hours 16 minutes | Carrier |
Delay causes
Why JetBlue runs late on this route
Late-arriving aircraft accounts for 48% of the 25,000 delay minutes carriers reported here, and the remaining four split what is left.
- 48%Late-arriving aircraft
- 29%Carrier
- 22%National Airspace System
- 1%Extreme weather
- 0%Security
48% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 25,000 reported delay minutes here, that single category outweighs weather by 48 to one. The split is drawn from 24,841 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 92.8% on time here.
Cancellations run at 4.12%, against 1.89% nationally. That is about one flight in 25 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
10.4% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
The 1,028 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 is a different operation and performs like one: it runs 71.9% on time across 1,383 flights, 6 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 6 points of difference.
The sample behind these figures is 1,384 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 JFK
Put together: the delay figures matter less here than the 4.12% 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. 1,323 completed flights over 12 months sit behind that.
