These figures cover 313 flights between July 2025 and June 2026. The median arrival is 12 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.
Schedule
When B6 1602 flies
B6 1602 flies JFK to BUF without a single fixed slot. Its most common scheduled departure was 07:30, used on 171 of 313 flights, with 07:50 (35 flights) and 07:55 (32 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 07:30 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and B6 1602 runs level with that at 87.7%. 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 1602 quarter by quarter
B6 1602 did not run the same all year. Its best quarter was Apr–Jun 2026 at 98.9% on time and its weakest Oct–Dec 2025 at 76.5%, a swing of 22 points on roughly 78 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 202584 flights87.8%
- Oct–Dec 202585 flights76.5%
- Jan–Mar 202653 flights85.4%
- Apr–Jun 202691 flights98.9%
Scale runs 70% to 100%. Rows with fewer than 30 flights show a dash.
By weekday, B6 1602 did best on Wednesday at 100.0% on time and worst on Friday at 77.3%. Each day rests on about 45 flights, so a gap of 23 points is worth noticing but could still narrow in another year.
Delay causes
Why B6 1602 runs late
One category carries most of the weight here. Carrier accounts for 49% of the 3,044 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.
- 49%Carrier
- 40%Late-arriving aircraft
- 9%National Airspace System
- 2%Security
40% 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 3,044 reported delay minutes here, that single category outweighs weather by 40 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 3,044 delay minutes reported on B6 1602.
Cancellations run at 3.83%, 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
5.3% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last an hour and a half, which a normal layover absorbs.
Every one of the 313 flights under B6 1602 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. 313 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 1602
For a booking, the cancellation rate is the figure to plan around on B6 1602: 3.83% of its 313 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.
