These figures cover 306 flights between July 2025 and June 2026. Beyond the headline rate, 15.3% 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 1017 flies

B6 1017 flies BOS to JFK without a single fixed slot. Its most common scheduled departure was 11:15, used on 55 of 306 flights. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 11:15 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and B6 1017 runs 11 points worse at 67.7%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

B6 1017 quarter by quarter

B6 1017 did not run the same all year. Its best quarter was Jul–Sep 2025 at 89.1% on time and its weakest Jan–Mar 2026 at 51.8%, a swing of 37 points on roughly 77 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.

Jul–Sep 202564 flights89.1%
Oct–Dec 202566 flights52.5%
Jan–Mar 202686 flights51.8%
Apr–Jun 202690 flights77.9%

Scale runs 45% to 95%. Rows with fewer than 30 flights show a dash.

By weekday, B6 1017 did best on Wednesday at 79.1% on time and worst on Saturday at 57.1%. Each day rests on about 44 flights, so a gap of 22 points is worth noticing but could still narrow in another year.

Delay causes

Why B6 1017 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 45% of the 7,062 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.

45%
National Airspace System
32%
Carrier
21%
Extreme weather
2%

45% 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 7,062 reported delay minutes here, that single category outweighs weather by 19 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 7,062 delay minutes reported on B6 1017.

Cancellations run at 3.92%, 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. 15.3% 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 306 flights under B6 1017 in the data flew BOS to JFK. 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. 306 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 1017

For a booking, the cancellation rate is the figure to plan around on B6 1017: 3.92% of its 306 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.
