Delay causes
Why B6 2255 runs late
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 8,826 reported delay minutes.
- 42%Late-arriving aircraft
- 33%National Airspace System
- 23%Carrier
- 2%Extreme weather
42% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 8,826 reported delay minutes here, that single category outweighs weather by 19 to one. The split is drawn from 8,826 delay minutes reported on B6 2255.
Cancellations run at 5.12%, against 1.89% nationally. That is about one flight in twenty 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
19.8% 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 293 flights under B6 2255 in the data flew BOS to DCA. 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. 293 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 2255
For a booking, the cancellation rate is the figure to plan around on B6 2255: 5.12% of its 293 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.
