B6 602 draws a D−. About one flight in three arrives at least 15 minutes late, and the typical late arrival is a little over an hour behind schedule. Build slack into anything you connect to. That rests on 312 flights, with a median arrival 1 minute late.

The national on-time rate over the same period is 77.6%, so B6 602 runs 13 points behind the country as a whole. Across a thousand flights that is about 131 extra late arrivals.

These figures cover 312 flights between July 2025 and June 2026. Beyond the headline rate, 16.6% 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 602 flies

B6 602 flies FLL to JFK without a single fixed slot. Its most common scheduled departure was 18:59, used on 45 of 312 flights, with 18:00 (32 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 18:59 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and B6 602 runs 4 points worse at 64.5%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Against the route

B6 602 next to FLL to JFK

Across the year

B6 602 quarter by quarter

B6 602 did not run the same all year. Its best quarter was Apr–Jun 2026 at 70.1% on time and its weakest Jan–Mar 2026 at 56.1%, a swing of 14 points on roughly 78 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.

Jan–Mar 202685 flights56.1%

By weekday, B6 602 did best on Tuesday at 72.2% on time and worst on Thursday at 58.3%. Each day rests on about 45 flights, so a gap of 14 points is worth noticing but could still narrow in another year.

Delay causes

Why B6 602 runs late

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 7,886 reported delay minutes.

37% 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 7,886 reported delay minutes here, that single category outweighs weather by 16 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 7,886 delay minutes reported on B6 602.

Cancellations run at 3.53%, 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 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. 16.6% 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 1,069 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 same number turns up on one other city pair in the data, including RSW to JFK (19), but none flew often enough under B6 602 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to FLL to JFK only.

One caution: this is a thin sample. 312 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 602

For a booking, the cancellation rate is the figure to plan around on B6 602: 3.53% of its 312 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
