Delay causes
Why B6 1286 runs late
Late-arriving aircraft accounts for 44% of the 4,228 delay minutes carriers reported here, and the remaining four split what is left.
- 44%Late-arriving aircraft
- 22%Extreme weather
- 20%National Airspace System
- 14%Carrier
Extreme weather accounts for 22% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 3.7 times the usual weather exposure. The split is drawn from 4,228 delay minutes reported on B6 1286.
Cancellations run at 2.90%, against 1.89% nationally. That is roughly 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
5.6% 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 a little over an hour, which a normal layover absorbs.
Every one of the 310 flights under B6 1286 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. 310 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 1286
For a booking, the cancellation rate is the figure to plan around on B6 1286: 2.90% of its 310 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.
