Delay causes
Why B6 675 runs late

- 52%Late-arriving aircraft

- 14%National Airspace System
- 4%Extreme weather
52% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 7,936 reported delay minutes here, that single category outweighs weather by 13 to one. The split is drawn from 7,936 delay minutes reported on B6 675.
Cancellations run at 3.56%, against 1.89% nationally. That is about one flight in 30 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
13.9% 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 365 flights under B6 675 in the data flew JFK to BDL. 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. 365 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 675
For a booking, the cancellation rate is the figure to plan around on B6 675: 3.56% of its 365 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
