Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Republic Airways.

Republic on MYR to DCA lands a B−, level with the national rate of 77.6%. Roughly one flight in four arrives 15 minutes late or worse, and those flights are late by roughly 50 minutes on average. That is a workable record, not a spotless one. That rests on 137 flights, with a median arrival 12 minutes early.

The US average over the same twelve months is 77.6%, 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.

Every carrier on MYR to DCA, 755 flights

These figures cover 137 flights between July 2025 and June 2026. The median arrival is 12 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 MYR to DCA

Republic flew 137 of the 755 flights on MYR to DCA, about 18% of it. Its 76.9% on time is 5 points better than the route as a whole, which runs 72.3%. 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 PSA at 71.1%. 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. Each bar is the on-time rate for flights scheduled inside that window.

  • 5am–8am
  • 8am–11am55 flights94.5%
  • 11am–2pm58 flights61.5%
  • 2pm–5pm16 flights
  • 5pm–8pm
  • 8pm–5am8 flights

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 94.5% 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.

Across the year

  • Jul–Sep 20254 flights
  • Oct–Dec 20259 flights
  • Jan–Mar 202668 flights66.1%

Scale runs 60% to 100%. 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 76.9% on time across 137 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 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 76.9% 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 62% of the 1,571 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.

  • Late-arriving aircraft
    62%
  • National Airspace System
    28%
  • Carrier
    11%
  • Extreme weather
    0%

62% 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 1,571 reported delay minutes here, that single category outweighs weather by 62 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 1,571 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 94.5% on time here.

Cancellations run at 5.11%, against 1.81% 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

6.9% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says 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 79.8% 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 MYR to DCA

Put together: the delay figures matter less here than the 5.11% 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. 130 completed flights over 12 months sit behind that.
