49% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 10,000 reported delay minutes here, that single category outweighs weather by 16 to one. The split is drawn from 10,090 delay minutes reported on B6 1202.

Connections and routes
What a delay on this flight costs
21.4% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
Every one of the 304 flights under B6 1202 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. 304 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 1202
For a booking, the cancellation rate is the figure to plan around on B6 1202: 7.57% of its 304 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.
