Historical statistics for July 2025 to June 2026, not live status. For today’s OH 5673, check with PSA Airlines. PSA Airlines flies under contract for larger airlines, so a ticket for this flight may show a different airline code and number.
OH 5673 earns a D−, which is as low as this site's scale goes for a reason. Only 56.9% of flights arrive inside the 15-minute window, 21 points worse than the national rate of 77.6%. Late arrivals average an hour and a half. Treat any tight connection here as a coin flip. That rests on 331 flights, with a median arrival 8 minutes late.
The national on-time rate over the same period is 77.6%, so OH 5673 runs 21 points behind the country as a whole. Across a thousand flights that is about 207 extra late arrivals.

These figures cover 331 flights between July 2025 and June 2026. Beyond the headline rate, 21.1% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Schedule
When OH 5673 flies
OH 5673 flies DCA to CVG without a single fixed slot. Its most common scheduled departure was 19:56, used on 46 of 331 flights, with 19:24 (37 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 19:56 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and OH 5673 runs 11 points worse at 56.9%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year
OH 5673 quarter by quarter
OH 5673 did not run the same all year. Its best quarter was Apr–Jun 2026 at 66.7% on time and its weakest Oct–Dec 2025 at 43.4%, a swing of 23 points on roughly 83 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

By weekday, OH 5673 did best on Monday at 66.0% on time and worst on Thursday at 50.0%. Each day rests on about 47 flights, so a gap of 16 points is worth noticing but could still narrow in another year.
Delay causes
Why OH 5673 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 53% of the 12,000 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.
- 53%Late-arriving aircraft
- 26%Carrier
- 13%National Airspace System
- 8%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. That is a cascade, and cascades start small and grow through the day. Across 12,000 reported delay minutes here, that single category outweighs weather by 7 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 11,681 delay minutes reported on OH 5673.
Cancellations run at 5.14%, against 1.81% nationally. That is about one flight in twenty 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
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 21.1% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum 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 (35), 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. 331 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: 5.14% of its 331 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.
