Delay causes
Why B6 1680 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 6,848 reported delay minutes.
- 40%Late-arriving aircraft
- 38%Carrier
- 20%National Airspace System
- 3%Extreme weather
40% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 6,848 reported delay minutes here, that single category outweighs weather by 15 to one. The split is drawn from 6,848 delay minutes reported on B6 1680.
Cancellations sit at 1.80% against a national 1.89%, which is ordinary. Diversions add another 0.90%.
Connections and routes
What a delay on this flight costs
10.5% 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.
The 899 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
Every one of the 333 flights under B6 1680 in the data flew FLL 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. 333 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 1680
