Share of 332 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 132 departures that left 15 minutes late or more, only 15 made it up before arrival. In the other direction, 29 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 PNS.

Delay causes
Why OH 5544 runs late
Late-arriving aircraft accounts for 52% of the 16,000 delay minutes carriers reported here, and the remaining four split what is left.
- 52%Late-arriving aircraft
- 23%Carrier
- 17%National Airspace System
- 8%Extreme weather
- 0%Security
52% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 16,000 reported delay minutes here, that single category outweighs weather by 7 to one. The split is drawn from 15,531 delay minutes reported on OH 5544.
Cancellations run at 6.98%, against 1.89% nationally. That is about one flight in fifteen 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
25.9% 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 816 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 358 flights under OH 5544 in the data flew DCA to PNS. 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. 358 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 5544
For a booking, the cancellation rate is the figure to plan around on OH 5544: 6.98% of its 358 scheduled flights did not operate. A late arrival costs close to two hours, but a cancellation costs the day, so leave a later option open.
