Delay causes
Why B6 1880 runs late
Late-arriving aircraft accounts for 44% of the 11,000 delay minutes carriers reported here, and the remaining four split what is left.
- 44%Late-arriving aircraft
- 33%National Airspace System
- 22%Carrier
- 1%Extreme weather
- 0%Security
44% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 11,000 reported delay minutes here, that single category outweighs weather by 41 to one. The split is drawn from 10,689 delay minutes reported on B6 1880.
Cancellations run at 3.52%, 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
19.9% 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.
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 341 flights under B6 1880 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. 341 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 1880
For a booking, the cancellation rate is the figure to plan around on B6 1880: 3.52% of its 341 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.
