These figures cover 281 flights between July 2025 and June 2026. Beyond the headline rate, 20.5% 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 102 flies

B6 102 flies JFK to BUF without a single fixed slot. Its most common scheduled departure was 22:15, used on 99 of 281 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 22:15 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and B6 102 runs 7 points worse at 63.3%. 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 102 quarter by quarter

B6 102 did not run the same all year. Its best quarter was Apr–Jun 2026 at 84.6% on time and its weakest Jul–Sep 2025 at 53.6%, a swing of 31 points on roughly 70 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 202570 flights54.4%
Jan–Mar 202665 flights68.3%
Apr–Jun 202654 flights84.6%

Scale runs 45% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, B6 102 did best on Monday at 70.3% on time and worst on Thursday at 56.4%. Each day rests on about 40 flights, so a gap of 14 points is worth noticing but could still narrow in another year.

Delay causes

Why B6 102 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 51% of the 8,423 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.

51% 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 8,423 reported delay minutes here, that single category outweighs weather by 10 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 8,423 delay minutes reported on B6 102.

Cancellations run at 5.69%, against 1.81% nationally. That is roughly one flight in twenty 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. 20.5% 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 281 flights under B6 102 in the data flew JFK to BUF. 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. 281 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 102

For a booking, the cancellation rate is the figure to plan around on B6 102: 5.69% of its 281 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.
