Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with JetBlue Airways.
JetBlue on EWR to FLL carries a cancellation problem, not just a delay problem: 4.6% of scheduled flights never operate, against 1.9% nationally. Of the ones that do fly, about seven flights in ten 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 1,060 flights. The strongest carrier on the route with a full sample, United Airlines, flew 2,723 at 78.2% on time.
The national on-time rate over the same period is 77.3%, so JetBlue on EWR to FLL runs 5 points behind the country as a whole. Across a thousand flights that is about 51 extra late arrivals.

Carrier by carrier
JetBlue against every carrier on EWR to FLL
JetBlue flew 1,060 of the 4,671 flights on EWR to FLL, about 23% of it. Its 72.2% on time is 3 points worse than the route as a whole, which runs 75.3%. Ranked by on-time rate it is number two of three carriers on the route, where the range runs from United at 78.2% to Spirit at 69.6%.
The choice of carrier is not cosmetic here. United Airlines arrives on time 78.2% of the time; Spirit Airlines manages 69.6%. Sample sizes sit next to every figure, because a two-point gap across 888 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| United Airlines | 2,723 | 78.2% | 71 min | 2.53% | B |
| JetBlue Airways (this page) | 1,060 | 72.2% | 82 min | 4.62% | C− |
| Spirit Airlines | 888 | 69.6% | 78 min | 7.88% | C− |
Spirit Airlines cancels 7.9% 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 27 points, against 9 points between the best and worst carrier.
- 5am–8am366 flights83.5%
- 8am–11am99 flights73.4%
- 11am–2pm113 flights81.2%
- 2pm–5pm137 flights56.2%

Scale runs 50% to 90%.
Book the early departure. Flights leaving between 5am–8am arrive on time 83.5% of the time, against 56.2% for the afternoon window. That is 27 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 5am–8am window is the busiest, with 366 flights scheduled in it.
Across the year
JetBlue on EWR to FLL through the year
December is the weak month at 52.2% on time, against 92.0% 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. August was the busiest month here, with 124 flights.
Across the week, Tuesday is the strongest day at 75.4% on time and Sunday the weakest at 61.9%, a spread of 14 points.

Share of 1,008 completed flights by arrival against schedule.
37 of 248 late departures made up the time and arrived on time, 15% of them. In the other direction, 69 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 FLL.
The worst days
Worst days for JetBlue on EWR to FLL
The latest arrival of the period was on 2 August 2026, 8 hours 21 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 |
|---|---|---|
| 2 August 2026 | 8 hours 21 minutes | Carrier |
| 11 July 2026 | 5 hours 32 minutes | Carrier |
| 19 July 2026 | 5 hours 15 minutes | Late-arriving aircraft |
| 18 January 2026 | 5 hours 10 minutes | Extreme weather |

Delay causes
Why JetBlue runs late on this route
Late-arriving aircraft accounts for 47% of the 23,000 delay minutes carriers reported here, and the remaining four split what is left.
- 47%Late-arriving aircraft
- 25%National Airspace System
- 24%Carrier
- 3%Extreme weather
- 0%Security
47% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 23,000 reported delay minutes here, that single category outweighs weather by 14 to one. The split is drawn from 22,959 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 83.5% on time here.
Cancellations run at 4.62%, against 1.89% nationally. That is roughly 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
13.0% 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 1,065 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 62.5% on time across 1,058 flights, 10 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 10 points of difference.
One caution: this is a thin sample. 1,060 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 FLL
Put together: the delay figures matter less here than the 4.62% 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. 1,008 completed flights over 12 months sit behind that.
