Delay causes
Why B6 2186 runs late

- 1%Extreme weather
48% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 6,216 reported delay minutes here, that single category outweighs weather by 48 to one. The split is drawn from 6,216 delay minutes reported on B6 2186.
Cancellations run at 6.79%, against 1.89% nationally. That is about one flight in fifteen 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
9.6% 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 280 flights under B6 2186 in the data flew PIT to BOS. 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. 280 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 2186
For a booking, the cancellation rate is the figure to plan around on B6 2186: 6.79% of its 280 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.
