Share of 326 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 43 departures that left 15 minutes late or more, only 2 made it up before arrival. In the other direction, 31 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.

- 5%Extreme weather
The largest share of delay minutes, 51%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 5,026 of the 9,825 delay minutes reported here. The split is drawn from 9,825 delay minutes reported on OH 5678.
Cancellations run at 7.87%, against 1.89% nationally. That is about one flight in twelve 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
10.7% 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 356 flights under OH 5678 in the data flew HPN 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. 356 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 OH 5678
For a booking, the cancellation rate is the figure to plan around on OH 5678: 7.87% of its 356 scheduled flights did not operate. A late arrival costs about 2.3 hours, but a cancellation costs the day, so leave a later option open.
