These figures cover 258 flights between September 2025 and August 2026. The median arrival is 17 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Share of 246 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 21 departures that left 15 minutes late or more, only 1 made it up before arrival. In the other direction, 13 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.

- 69%Carrier
- 24%Late-arriving aircraft

- 0%Extreme weather
The largest share of delay minutes, 69%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 5,093 of the 7,417 delay minutes reported here. The split is drawn from 7,417 delay minutes reported on OH 5603.
Cancellations run at 4.65%, against 1.89% 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
6.9% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about 3.7 hours, which a normal layover absorbs.
The same number turns up on two other city pairs in the data, including BTR to DFW (6) and SAV to DFW (4), but none flew often enough under OH 5603 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to CAE to DCA only.
One caution: this is a thin sample. 258 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 5603
For a booking, the cancellation rate is the figure to plan around on OH 5603: 4.65% of its 258 scheduled flights did not operate. A late arrival costs about 3.7 hours, but a cancellation costs the day, so leave a later option open.
