These figures cover 321 flights between July 2025 and June 2026. Beyond the headline rate, 9.7% 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 418 flies

B6 418 flies JFK to BOS without a single fixed slot. Its most common scheduled departure was 10:30, used on 53 of 321 flights, with 13:00 (49 flights) and 13:10 (42 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 10:30 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and B6 418 runs 9 points worse at 75.6%. 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 418 quarter by quarter

B6 418 did not run the same all year. Its best quarter was Apr–Jun 2026 at 90.0% on time and its weakest Oct–Dec 2025 at 64.7%, a swing of 25 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.

By weekday, B6 418 did best on Friday at 79.5% on time and worst on Thursday at 65.2%. Each day rests on about 46 flights, so a gap of 14 points is worth noticing but could still narrow in another year.

Delay causes

Why B6 418 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 43% of the 5,743 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

43% 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 5,743 reported delay minutes here, that single category outweighs weather by 43 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 5,743 delay minutes reported on B6 418.

Cancellations run at 4.05%, against 1.81% nationally. That is about 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

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 9.7% 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.

Every one of the 321 flights under B6 418 in the data flew JFK to BOS. 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 418

For a booking, the cancellation rate is the figure to plan around on B6 418: 4.05% 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.
