- 2%Extreme weather
44% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 8,062 reported delay minutes here, that single category outweighs weather by 22 to one. The split is drawn from 8,062 delay minutes reported on B6 1017.

Connections and routes
What a delay on this flight costs
17.5% 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 306 flights under B6 1017 in the data flew BOS 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. 306 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 1017
For a booking, the cancellation rate is the figure to plan around on B6 1017: 4.90% of its 306 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.
