These figures cover 326 flights between July 2025 and June 2026. The median arrival is 9 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.
Schedule
When B6 569 flies
B6 569 flies BOS to FLL without a single fixed slot. Its most common scheduled departure was 06:00, used on 69 of 326 flights, with 06:40 (53 flights) and 06:10 (39 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 06:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and B6 569 runs 9 points worse at 80.4%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year
B6 569 quarter by quarter
B6 569 did not run the same all year. Its best quarter was Jul–Sep 2025 at 87.6% on time and its weakest Jan–Mar 2026 at 64.4%, a swing of 23 points on roughly 82 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.

- Oct–Dec 202554 flights86.3%
- Jan–Mar 202690 flights64.4%
- Apr–Jun 202690 flights85.4%
Scale runs 55% to 95%. Rows with fewer than 30 flights show a dash.
By weekday, B6 569 ranged from 75.6% on Thursday to 85.7% on Monday. With about 47 flights behind each day, a spread of 10 points is inside normal variation, so the day you fly is not worth changing for this flight.
Delay causes
Why B6 569 runs late
One category carries most of the weight here. National Airspace System accounts for 54% of the 2,596 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.
- 54%National Airspace System
- 36%Carrier
- 9%Late-arriving aircraft
The largest share of delay minutes, 36%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 947 of the 2,596 delay minutes reported here. The split is drawn from 2,596 delay minutes reported on B6 569.
Cancellations run at 3.07%, against 1.81% nationally. That is roughly 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
Badly late arrivals are rare here: only 2.8% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
The 1,237 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 326 flights under B6 569 in the data flew BOS to FLL. 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. 326 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 569
For a booking, the cancellation rate is the figure to plan around on B6 569: 3.07% of its 326 scheduled flights did not operate. A late arrival costs roughly 40 minutes, but a cancellation costs the day, so leave a later option open.
