16 of 104 late departures made up the time and arrived on time, 15% of them. In the other direction, 27 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at PBI.

Delay causes
Why B6 23 runs late
Late-arriving aircraft accounts for 58% of the 9,442 delay minutes carriers reported here, and the remaining four split what is left.
- 58%Late-arriving aircraft
- 22%National Airspace System
- 20%Carrier
- 1%Extreme weather
58% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 9,442 reported delay minutes here, that single category outweighs weather by 53 to one. The split is drawn from 9,442 delay minutes reported on B6 23.
Cancellations run at 2.73%, against 1.89% nationally. That is roughly one flight in 40 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
16.5% 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 857 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 293 flights under B6 23 in the data flew DCA to PBI. 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 23
For a booking, the cancellation rate is the figure to plan around on B6 23: 2.73% of its 293 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.
