Share of 302 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 112 departures that left 15 minutes late or more, only 7 made it up before arrival. In the other direction, 26 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 DCA.
The worst days
Worst days for B6 24
The latest arrival of the period was on 14 December 2025, 8 hours 39 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). On three of the five worst days the largest share was filed as a late-arriving aircraft.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 14 December 2025 | 8 hours 39 minutes | Carrier |
| 12 June 2026 | 7 hours 49 minutes | National Airspace System |
| 10 May 2026 | 6 hours 33 minutes | Late-arriving aircraft |

Delay causes
Why B6 24 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 10,000 reported delay minutes.
- 41%National Airspace System
- 40%Late-arriving aircraft
- 17%Carrier
- 1%Extreme weather
- 0%Security
40% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 10,000 reported delay minutes here, that single category outweighs weather by 40 to one. The split is drawn from 10,122 delay minutes reported on B6 24.
Cancellations sit at 2.26% against a national 1.89%, which is ordinary. Diversions add another 0.32%.
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 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 310 flights under B6 24 in the data flew PBI 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. 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 24
For a booking, B6 24 is a flight to put a long connection behind. 19.9% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
