These figures cover 355 flights between July 2025 and June 2026. Beyond the headline rate, 18.7% 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 471 flies

B6 471 flies LGA to FLL without a single fixed slot. Its most common scheduled departure was 12:30, used on 123 of 355 flights, with 15:55 (76 flights) and 15:50 (53 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 12:30 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and B6 471 runs 20 points worse at 59.2%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

B6 471 quarter by quarter

B6 471 did not run the same all year. Its best quarter was Jan–Mar 2026 at 75.9% on time and its weakest Jul–Sep 2025 at 45.7%, a swing of 30 points on roughly 89 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.

By weekday, B6 471 did best on Wednesday at 72.9% on time and worst on Friday at 48.0%. Each day rests on about 51 flights, so a gap of 25 points is worth noticing but could still narrow in another year.

Delay causes

Why B6 471 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 42% of the 12,000 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.

Extreme weather
6%

42% 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 12,000 reported delay minutes here, that single category outweighs weather by 7 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 11,837 delay minutes reported on B6 471.

Cancellations run at 3.10%, 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. 18.7% 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 355 flights under B6 471 in the data flew LGA 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. 355 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 471

For a booking, the cancellation rate is the figure to plan around on B6 471: 3.10% of its 355 scheduled flights did not operate. A late arrival costs an hour and a half, but a cancellation costs the day, so leave a later option open.
