Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Republic Airways.
Republic on DCA to MYR lands a B−, 2 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by about 40 minutes on average. That is a workable record, not a spotless one. That rests on 137 flights, with a median arrival 10 minutes early.
The US average over the same twelve months is 77.6%, so there is little to separate Republic on DCA to MYR from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Every carrier on DCA to MYR, 755 flights
These figures cover 137 flights between July 2025 and June 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 DCA to MYR
Republic flew 137 of the 755 flights on DCA to MYR, about 18% of it. Its 79.8% on time is 2 points better than the route as a whole, which runs 77.4%. 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 25.0%. 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 is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 137 flights.
There are not enough flights in each departure window to split Republic's DCA to MYR record by time of day without the percentages moving on noise. The headline rate of 79.8% is the reliable figure here.
Across the year

Scale runs 65% to 95%. Rows with fewer than 30 flights show a dash.
Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 79.8% on time across 137 flights.
Split by quarter, Republic on DCA to MYR logged 4 flights in Jul–Sep 2025, 9 flights in Oct–Dec 2025, 68 flights in Jan–Mar 2026 and 56 flights in Apr–Jun 2026. Fewer than three of those quarters carried the 30 completed flights this site needs before printing a rate, so the 79.8% annual figure is the one to use.
Delay causes
Why Republic runs late on this route
One category carries most of the weight here. Late-arriving aircraft accounts for 65% of the 1,026 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.
- 65%Late-arriving aircraft
- 25%National Airspace System
- 11%Carrier
65% 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 1,026 reported delay minutes here, that single category outweighs weather by 65 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 1,026 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 81.1% on time here.
Cancellations run at 5.84%, against 1.81% nationally. That is roughly one flight in fifteen 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 3.9% land an hour or more behind schedule, against 8.1% 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 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 76.9% on time across 137 flights, within 3 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. 137 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 DCA to MYR
Put together: the delay figures matter less here than the 5.84% cancellation rate. A late arrival costs you about 40 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. 129 completed flights over 12 months sit behind that.
