These figures cover 342 flights between September 2025 and August 2026. The median arrival is 11 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.

Share of 327 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 30 departures that left 15 minutes late or more, only 3 made it up before arrival. In the other direction, 26 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at JFK.

Worst days for B6 2001
The latest arrival of the period was on 27 January 2026, 4 hours 58 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on five of the five worst days.

- 64%Carrier
- 32%National Airspace System
- 4%Late-arriving aircraft
The largest share of delay minutes, 64%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,308 of the 3,591 delay minutes reported here. The split is drawn from 3,591 delay minutes reported on B6 2001.
Cancellations run at 4.39%, against 1.89% nationally. That is roughly 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
5.5% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.
Every one of the 342 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. 342 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: 4.39% of its 342 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
