These figures cover 321 flights between September 2025 and August 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.

Delay causes
Why B6 1602 runs late
Carrier accounts for 49% of the 3,152 delay minutes carriers reported here, and the remaining four split what is left.
- 49%Carrier
- 37%Late-arriving aircraft
- 11%National Airspace System
- 2%Security
37% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,152 reported delay minutes here, that single category outweighs weather by 37 to one. The split is drawn from 3,152 delay minutes reported on B6 1602.
Cancellations run at 5.61%, against 1.89% 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
6.6% 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 an hour and a half, which a normal layover absorbs.
Every one of the 321 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. 321 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: 5.61% of its 321 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.
