These figures cover 350 flights between July 2025 and June 2026. Beyond the headline rate, 17.1% 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 272 flies
B6 272 flies FLL to LGA without a single fixed slot. Its most common scheduled departure was 17:40, used on 56 of 350 flights. 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 17:40 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and B6 272 runs 9 points worse at 59.6%. 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 272 quarter by quarter
B6 272 did not run the same all year. Its best quarter was Jul–Sep 2025 at 69.0% on time and its weakest Jan–Mar 2026 at 53.5%, a swing of 16 points on roughly 88 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 202591 flights55.8%
- Jan–Mar 202690 flights53.5%

Scale runs 45% to 75%. Rows with fewer than 30 flights show a dash.
By weekday, B6 272 did best on Wednesday at 74.5% on time and worst on Tuesday at 52.0%. Each day rests on about 50 flights, so a gap of 23 points is worth noticing but could still narrow in another year.
Delay causes
Why B6 272 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 9,280 reported delay minutes.
- 42%National Airspace System
- 36%Late-arriving aircraft
- 21%Carrier
- 2%Extreme weather
- 0%Security
36% 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 9,280 reported delay minutes here, that single category outweighs weather by 21 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 9,280 delay minutes reported on B6 272.
Cancellations run at 2.57%, against 1.81% nationally. That is about one flight in 40 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. 17.1% 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 350 flights under B6 272 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. 350 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 272
For a booking, the cancellation rate is the figure to plan around on B6 272: 2.57% of its 350 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
