Historical statistics for July 2025 to June 2026, not live status. For today’s B6 706, check with JetBlue Airways.
B6 706 earns an F, which is as low as this site's scale goes for a reason. Only 51.5% of flights arrive inside the 15-minute window, 26 points worse than the national rate of 77.6%. Late arrivals average a little over an hour. Treat any tight connection here as a coin flip. That rests on 348 flights, with a median arrival 12 minutes late.
The national on-time rate over the same period is 77.6%, so B6 706 runs 26 points behind the country as a whole. Across a thousand flights that is about 261 extra late arrivals.

These figures cover 348 flights between July 2025 and June 2026. Beyond the headline rate, 24.3% 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.
Schedule
When B6 706 flies
B6 706 flies FLL to EWR without a single fixed slot. Its most common scheduled departure was 20:00, used on 150 of 348 flights, with 20:05 (93 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 20:00 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and B6 706 runs 19 points worse at 51.5%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year
B6 706 quarter by quarter
B6 706 did not run the same all year. Its best quarter was Apr–Jun 2026 at 61.1% on time and its weakest Oct–Dec 2025 at 42.4%, a swing of 19 points on roughly 87 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

By weekday, B6 706 did best on Saturday at 66.0% on time and worst on Monday at 42.0%. Each day rests on about 50 flights, so a gap of 24 points is worth noticing but could still narrow in another year.
Delay causes
Why B6 706 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 43% of the 12,000 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.
- 43%Late-arriving aircraft
- 36%National Airspace System
- 20%Carrier
- 1%Extreme weather
- 0%Security
43% 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 12,000 reported delay minutes here, that single category outweighs weather by 37 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 12,451 delay minutes reported on B6 706.
Cancellations sit at 2.30% against a national 1.81%, which is ordinary. Diversions add another 0.57%.
Connections and routes
What a delay on this flight costs
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 24.3% 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.
Every one of the 348 flights under B6 706 in the data flew FLL to EWR. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 348 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 B6 706
For a booking, B6 706 is a flight to put a long connection behind. 24.3% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
