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 Jul–Sep 2026 at 35.7%, a swing of 30 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.

20 of 143 late departures made up the time and arrived on time, 14% of them. In the other direction, 26 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at LGA.

Delay causes
Why B6 572 runs late
National Airspace System accounts for 47% of the 10,000 delay minutes carriers reported here, and the remaining four split what is left.
- 47%National Airspace System
- 30%Carrier
- 23%Late-arriving aircraft
- 1%Extreme weather
- 0%Security
47% 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 4,823 minutes out of 10,000, against a national NAS share of 21%. The split is drawn from 10,291 delay minutes reported on B6 572.
Cancellations run at 4.36%, against 1.89% nationally. That is roughly one flight in 25 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
19.5% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection 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.
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: 4.36% 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.
