Historical statistics for July 2025 to June 2026, not live status. For today’s OH 5473, 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 5473 earns an F−, which is as low as this site's scale goes for a reason. Only 54.5% of flights arrive inside the 15-minute window, 23 points worse than the national rate of 77.6%. Late arrivals average a little over an hour. Treat any tight connection here as a coin flip. That rests on 253 flights, with a median arrival 10 minutes late.
The national on-time rate over the same period is 77.6%, so OH 5473 runs 23 points behind the country as a whole. Across a thousand flights that is about 231 extra late arrivals.

These figures cover 253 flights between July 2025 and June 2026. Beyond the headline rate, 20.8% 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 5473 flies
OH 5473 flies DCA to DAY without a single fixed slot. Its most common scheduled departure was 22:00, used on 49 of 253 flights, with 22:02 (46 flights) and 22:05 (32 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.
- Departs 22:0049 flights19.4%
- Departs 22:0246 flights18.2%
- Departs 22:0532 flights12.6%
Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.
Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 22:00 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and OH 5473 runs 16 points worse at 54.5%. 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 5473 quarter by quarter
OH 5473 did not run the same all year. Its best quarter was Oct–Dec 2025 at 63.2% on time and its weakest Jan–Mar 2026 at 44.8%, a swing of 18 points on roughly 84 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.
- Jul–Sep 202530 flights—
- Oct–Dec 202580 flights63.2%
- Jan–Mar 202678 flights44.8%
- Apr–Jun 202665 flights58.1%
Scale runs 35% to 70%. Rows with fewer than 30 flights show a dash.
By weekday, OH 5473 did best on Monday at 63.2% on time and worst on Thursday at 45.0%. Each day rests on about 36 flights, so a gap of 18 points is worth noticing but could still narrow in another year.
Delay causes
Why OH 5473 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 47% of the 7,807 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.
- 47%Late-arriving aircraft
- 39%Carrier
- 11%National Airspace System
- 2%Extreme weather
47% 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 7,807 reported delay minutes here, that single category outweighs weather by 22 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 7,807 delay minutes reported on OH 5473.
Cancellations run at 8.30%, against 1.81% 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
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 20.8% 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 two other city pairs in the data, including ECP to DFW (61) and DFW to ECP (61), but none flew often enough under OH 5473 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DCA to DAY only.
One caution: this is a thin sample. 253 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 5473
For a booking, the cancellation rate is the figure to plan around on OH 5473: 8.30% of its 253 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
