Republic on MYR to DCA sits in the middle of the pack with a B−. Close to three flights in four arrive on time by the DOT's definition, 2 points worse than the national rate of 77.3%. The late ones land roughly 50 minutes behind schedule. That rests on 143 flights, with a median arrival 12 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate Republic on MYR to DCA from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Carrier by carrier
Republic against every carrier on MYR to DCA
Republic flew 143 of the 753 flights on MYR to DCA, about 19% of it. Its 75.7% on time is 5 points better than the route as a whole, which runs 70.6%. Ranked by on-time rate it is number two of four carriers on the route, where the range runs from American at 100.0% to Envoy at 47.8%. Two 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 33 points, against half a point between the best and worst carrier.

- 11am–2pm58 flights61.5%

Scale runs 55% 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 61.5% on time against 94.6% for 8am–11am. 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 11am–2pm window is the busiest, with 58 flights scheduled in it.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 75.7% on time across 143 flights.
Split by quarter, Republic on MYR to DCA logged 4 flights in Jul–Sep 2025, 9 flights in Oct–Dec 2025, 68 flights in Jan–Mar 2026, 56 flights in Apr–Jun 2026 and 6 flights in Jul–Sep 2026. Fewer than three of those quarters carried the 30 completed flights this site needs before printing a rate, so the 75.7% annual figure is the one to use.

Share of 136 completed flights by arrival against schedule.
4 of 26 late departures made up the time and arrived on time, 15% of them. In the other direction, 11 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.
The worst days
Worst days for Republic on MYR to DCA
The latest arrival of the period was on 14 February 2026, 4 hours 54 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 |
|---|---|---|
| 14 February 2026 | 4 hours 54 minutes | Late-arriving aircraft |
| 21 January 2026 | 1 hour 37 minutes | Carrier |
| 30 April 2026 | 1 hour 27 minutes | Late-arriving aircraft |
| 1 December 2025 | 1 hour 26 minutes | Late-arriving aircraft |
| 5 March 2026 | 1 hour 19 minutes | National Airspace System |
Delay causes
Why Republic runs late on this route
Late-arriving aircraft accounts for 64% of the 1,727 delay minutes carriers reported here, and the remaining four split what is left.
- 64%Late-arriving aircraft
- 26%National Airspace System
- 10%Carrier
- 1%Extreme weather
64% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 1,727 reported delay minutes here, that single category outweighs weather by 64 to one. The split is drawn from 1,727 reported delay minutes.
The practical consequence: the 8am–11am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 94.6% on time here.
Cancellations run at 4.90%, 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 stage length
What a delay here costs
8.1% 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 roughly 50 minutes, which a normal layover absorbs.
At 372 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 8am–11am window matters as much as it does.
The return leg runs 77.8% on time across 143 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. 143 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 MYR to DCA
Put together: the delay figures matter less here than the 4.90% cancellation rate. A late arrival costs you roughly 50 minutes; a cancelled flight costs you the day. Book the 8am–11am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 136 completed flights over 12 months sit behind that.
