These figures cover 117 flights between September 2025 and August 2026. The median arrival is 10 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.

Carrier by carrier
Republic against every carrier on CAE to DCA
Republic flew 117 of the 1,093 flights on CAE to DCA, about 11% of it. Its 85.1% on time is 13 points better than the route as a whole, which runs 72.6%. Ranked by on-time rate it is number two of three carriers on the route, where the range runs from Envoy at 91.7% to PSA at 69.9%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

Departure window
When Republic runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 24 points, against half a point between the best and worst carrier.

- 8am–11am35 flights80.0%
- 11am–2pm37 flights73.5%

- 8pm–5am—
Scale runs 65% to 100%. Rows with fewer than 30 flights show a dash.
The weak window here is the middle of the day, not the evening: 11am–2pm runs 73.5% on time against 97.7% for 5am–8am. That shape usually means a departure bank rather than an accumulating delay, so the recovery later in the afternoon is real rather than noise. The 5am–8am window is the busiest, with 44 flights scheduled in it.

The worst days
Worst days for Republic on CAE to DCA
The latest arrival of the period was on 22 September 2025, 4 hours 28 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 22 September 2025 | 4 hours 28 minutes | Late-arriving aircraft |
| 7 February 2026 | 1 hour 39 minutes | Carrier |
| 1 February 2026 | 1 hour 19 minutes | Late-arriving aircraft |

Delay causes
Why Republic runs late on this route
Late-arriving aircraft accounts for 55% of the 959 delay minutes carriers reported here, and the remaining four split what is left.
- 55%Late-arriving aircraft
- 22%National Airspace System
- 20%Carrier
- 2%Extreme weather
- 2%Security
55% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 959 reported delay minutes here, that single category outweighs weather by 33 to one. The split is drawn from 959 reported delay minutes.
The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 97.7% on time here.
Cancellations run at 2.56%, against 1.89% nationally. That is about one flight in 40 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 stage length
What a delay here costs
Badly late arrivals are rare here: only 3.5% land an hour or more behind schedule, against 8.3% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
At 408 miles this is a short hop, and stage length matters more than it looks. A flight this short spends under two hours in the air, which leaves almost nothing to claw back a late pushback with. Delay here is decided on the ground, in the turn, which is why the 5am–8am window matters as much as it does.
The return leg runs 82.7% on time across 116 flights, within 2 points of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
One caution: this is a thin sample. 117 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 Republic on CAE to DCA
Put together: treat all of this as provisional. 117 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 85.1% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 114 completed flights over 12 months sit behind that.
