B6 572 earns a D−, which is as low as this site's scale goes for a reason. Only 55.6% of flights arrive inside the 15-minute window, 22 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 321 flights, with a median arrival 9 minutes late.
The national on-time rate over the same period is 77.6%, so B6 572 runs 22 points behind the country as a whole. Across a thousand flights that is about 220 extra late arrivals.

These figures cover 321 flights between July 2025 and June 2026. Beyond the headline rate, 19.4% 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 572 flies
B6 572 flies FLL to LGA without a single fixed slot. Its most common scheduled departure was 20:05, used on 97 of 321 flights, with 20:40 (47 flights) and 20:20 (38 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 20:05 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and B6 572 runs 15 points worse at 55.6%. 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 572 quarter by quarter
B6 572 did not run the same all year. Its best quarter was Apr–Jun 2026 at 65.5% on time and its weakest Oct–Dec 2025 at 43.1%, a swing of 22 points on roughly 80 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.
- Jul–Sep 202584 flights64.6%
- Oct–Dec 202561 flights43.1%
- Jan–Mar 202690 flights45.8%
- Apr–Jun 202686 flights65.5%
Scale runs 35% to 70%. Rows with fewer than 30 flights show a dash.
By weekday, B6 572 did best on Tuesday at 74.3% on time and worst on Sunday at 42.2%. Each day rests on about 46 flights, so a gap of 32 points is worth noticing but could still narrow in another year.
Delay causes
Why B6 572 runs late
One category carries most of the weight here. National Airspace System accounts for 52% of the 9,344 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.
- 52%National Airspace System
- 27%Carrier
- 21%Late-arriving aircraft
- 1%Extreme weather
52% 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 4,867 minutes out of 9,344, against a national NAS share of 21%. The split is drawn from 9,344 delay minutes reported on B6 572.
Cancellations run at 3.12%, 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. 19.4% 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 1,076 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 321 flights under B6 572 in the data flew FLL to LGA. 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. 321 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 572
For a booking, the cancellation rate is the figure to plan around on B6 572: 3.12% of its 321 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.
