Historical statistics for July 2025 to June 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: 3.6% of scheduled flights never operate, against 1.8% 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 1,004 flights. The strongest carrier on the route with a full sample, United Airlines, flew 2,677 at 77.3% on time.
The national on-time rate over the same period is 77.6%, so JetBlue on FLL to EWR runs 15 points behind the country as a whole. Across a thousand flights that is about 153 extra late arrivals.

These figures cover 1,004 flights between July 2025 and June 2026. Beyond the headline rate, 16.9% 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 FLL to EWR
JetBlue flew 1,004 of the 4,752 flights on FLL to EWR, about 21% of it. Its 62.3% on time is 8 points worse than the route as a whole, which runs 70.4%. Ranked by on-time rate it is number two of three carriers on the route, where the range runs from United at 77.3% to Spirit at 60.0%.
The choice of carrier is not cosmetic here. United Airlines arrives on time 77.3% of the time; Spirit Airlines manages 60.0%. Sample sizes sit next to every figure, because a two-point gap across 1,071 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| United Airlines | 2,677 | 77.3% | 83 min | 2.20% | B |
| JetBlue Airways (this page) | 1,004 | 62.3% | 71 min | 3.59% | D− |
| Spirit Airlines | 1,071 | 60.0% | 71 min | 5.79% | D− |
Spirit Airlines cancels 5.8% 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 40 points, against 17 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am189 flights89.8%
- 8am–11am123 flights74.8%
- 11am–2pm81 flights56.4%
- 2pm–5pm76 flights50.0%
- 5pm–8pm182 flights52.1%
- 8pm–5am353 flights51.9%
Scale runs 40% to 95%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 89.8% of the time, against 50.0% for the afternoon window. That is 40 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. April was the busiest month here, with 102 flights.
Across the week, Wednesday is the strongest day at 71.1% on time and Sunday the weakest at 51.1%. 20 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 26,000 reported delay minutes.
- 39%Late-arriving aircraft
- 38%National Airspace System
- 22%Carrier
- 1%Extreme weather
- 0%Security
39% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 26,000 reported delay minutes here, that single category outweighs weather by 32 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 25,916 reported delay minutes.
38% 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 9,840 minutes out of 26,000, against a national NAS share of 21%.
Cancellations run at 3.59%, against 1.81% 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
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 16.9% 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 1,065 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. 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 is a different operation and performs like one: it runs 72.4% on time across 1,003 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. 1,004 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 3.59% 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. 964 completed flights over 12 months sit behind that.
