Time lost at the gate mostly stays lost. Of 118 departures that left 15 minutes late or more, only 12 made it up before arrival. In the other direction, 15 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 CVG.

Delay causes
Why OH 5673 runs late
Late-arriving aircraft accounts for 53% of the 11,000 delay minutes carriers reported here, and the remaining four split what is left.
- 53%Late-arriving aircraft
- 24%Carrier
- 13%National Airspace System
- 10%Extreme weather
- 0%Security
53% 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 5 to one. The split is drawn from 10,540 delay minutes reported on OH 5673.
Cancellations run at 4.03%, against 1.89% nationally. That is about one flight in 25 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
20.7% 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.
The same number turns up on one other city pair in the data, including CVG to DCA (59), but none flew often enough under OH 5673 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DCA to CVG only.
One caution: this is a thin sample. 298 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 5673
For a booking, the cancellation rate is the figure to plan around on OH 5673: 4.03% of its 298 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.
