Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with JetBlue Airways.
JetBlue on FLL to EWR carries a cancellation problem, not just a delay problem: 4.3% of scheduled flights never operate, against 1.9% nationally. Of the ones that do fly, a little over half of flights arrive on time, worth a D− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 1,058 flights. The strongest carrier on the route with a full sample, United Airlines, flew 2,721 at 78.1% on time.
The national on-time rate over the same period is 77.3%, so JetBlue on FLL to EWR runs 15 points behind the country as a whole. Across a thousand flights that is about 148 extra late arrivals.

Carrier by carrier
JetBlue against every carrier on FLL to EWR
JetBlue flew 1,058 of the 4,666 flights on FLL to EWR, about 23% of it. Its 62.5% on time is 9 points worse than the route as a whole, which runs 71.1%. Ranked by on-time rate it is number two of three carriers on the route, where the range runs from United at 78.1% to Spirit at 58.9%.
The choice of carrier is not cosmetic here. United Airlines arrives on time 78.1% of the time; Spirit Airlines manages 58.9%. Sample sizes sit next to every figure, because a two-point gap across 887 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| United Airlines | 2,721 | 78.1% | 82 min | 2.57% | B |
| JetBlue Airways (this page) | 1,058 | 62.5% | 69 min | 4.25% | D− |
| Spirit Airlines | 887 | 58.9% | 70 min | 6.54% | D− |
Spirit Airlines cancels 6.5% 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 42 points, against 19 points between the best and worst carrier.
- 5am–8am189 flights92.0%
- 8am–11am123 flights74.8%
- 11am–2pm135 flights58.6%

Scale runs 40% to 95%.
Book the early departure. Flights leaving between 5am–8am arrive on time 92.0% of the time, against 50.0% for the afternoon window. That is 42 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8pm–5am window is the busiest, with 353 flights scheduled in it.
Across the year
JetBlue on FLL to EWR through the year
December is the weak month at 45.6% on time, against 76.0% 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, Wednesday is the strongest day at 72.5% on time and Sunday the weakest at 50.0%, a spread of 23 points.

The worst days
Worst days for JetBlue on FLL to EWR
The latest arrival of the period was on 16 March 2026, 7 hours 30 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 16 March 2026 | 7 hours 30 minutes | Late-arriving aircraft |
| 15 February 2026 | 6 hours 26 minutes | Late-arriving aircraft |
| 9 November 2025 | 5 hours 56 minutes | Late-arriving aircraft |

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 26,000 reported delay minutes.
- 37%Late-arriving aircraft
- 36%National Airspace System
- 26%Carrier
- 1%Extreme weather
- 0%Security
37% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 26,000 reported delay minutes here, that single category outweighs weather by 37 to one. The split is drawn from 26,147 reported delay minutes.
36% 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 9,426 minutes out of 26,000, against a national NAS share of 21%.
Cancellations run at 4.25%, 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
16.6% 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 72.2% on time across 1,060 flights, 10 points above 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. 1,058 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 FLL to EWR
Put together: the delay figures matter less here than the 4.25% cancellation rate. A late arrival costs you a little over 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. 1,008 completed flights over 12 months sit behind that.
