These figures cover 334 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 2001 flies
B6 2001 flies BUF to JFK without a single fixed slot. Its most common scheduled departure was 06:00, used on 122 of 334 flights, with 07:00 (99 flights) and 05:35 (50 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 06:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and B6 2001 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 2001 quarter by quarter
B6 2001 did not run the same all year. Its best quarter was Apr–Jun 2026 at 96.6% on time and its weakest Jan–Mar 2026 at 74.7%, a swing of 22 points on roughly 84 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 202576 flights81.1%
- Jan–Mar 202685 flights74.7%

By weekday, B6 2001 did best on Saturday at 95.9% on time and worst on Thursday at 80.9%. Each day rests on about 48 flights, so a gap of 15 points is worth noticing but could still narrow in another year.
Delay causes
Why B6 2001 runs late
One category carries most of the weight here. Carrier accounts for 65% of the 2,877 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.
- 65%Carrier
- 30%National Airspace System
- 5%Late-arriving aircraft
The largest share of delay minutes, 65%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 1,868 of the 2,877 delay minutes reported here. The split is drawn from 2,877 delay minutes reported on B6 2001.
Cancellations run at 2.69%, 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
Badly late arrivals are rare here: only 3.4% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
Every one of the 334 flights under B6 2001 in the data flew BUF 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. 334 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 2001
For a booking, the cancellation rate is the figure to plan around on B6 2001: 2.69% of its 334 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.
