These figures cover 299 flights between July 2025 and June 2026. Beyond the headline rate, 16.2% 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 1118 flies

B6 1118 flies JFK to BOS without a single fixed slot. Its most common scheduled departure was 22:59, used on 80 of 299 flights, with 22:30 (61 flights) and 12:30 (45 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 22:59 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and B6 1118 runs 8 points worse at 62.9%. 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 1118 quarter by quarter

B6 1118 did not run the same all year. Its best quarter was Apr–Jun 2026 at 70.3% on time and its weakest Jan–Mar 2026 at 46.0%, a swing of 24 points on roughly 100 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 1118 did best on Wednesday at 73.8% on time and worst on Sunday at 43.9%. Each day rests on about 43 flights, so a gap of 30 points is worth noticing but could still narrow in another year.

Delay causes

Why B6 1118 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 7,687 reported delay minutes.

Late-arriving aircraft
41%
Carrier
33%
National Airspace System

Security

Extreme weather
0%

41% 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 7,687 reported delay minutes here, that single category outweighs weather by 41 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 7,687 delay minutes reported on B6 1118.

Cancellations run at 2.68%, 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. 16.2% 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 299 flights under B6 1118 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. 299 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 1118

For a booking, the cancellation rate is the figure to plan around on B6 1118: 2.68% of its 299 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.
