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

Republic on MYR to EWR lands a B−, about a point worse than the national rate of 77.6%. About one flight in four arrives 15 minutes late or worse, and those flights are late by an hour and a half on average. That is a workable record, not a spotless one. That rests on 487 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 MYR to EWR 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 EWR, 1,006 flights

These figures cover 487 flights between July 2025 and June 2026. Beyond the headline rate, 8.7% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Carrier by carrier

Republic against every carrier on MYR to EWR

Republic flew 487 of the 1,006 flights on MYR to EWR, about 48% of it. Its 76.7% on time is 2 points worse than the route as a whole, which runs 79.0%. Ranked by on-time rate it is last of three carriers on the route, where the range runs from United at 82.8% to Republic at 76.7%. 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 19 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

8am–11am6 flights—
11am–2pm225 flights86.4%
2pm–5pm1 flights—
5pm–8pm255 flights67.2%
8pm–5am—

Scale runs 60% to 90%. Rows with fewer than 30 flights show a dash.

The best window here is not the first bank but the 11am–2pm slot at 86.4% on time, ahead of 5pm–8pm at 67.2%. Where the curve peaks mid-day rather than at dawn, the constraint is usually congestion at one end rather than the aircraft's own rotation. The 5pm–8pm window is the busiest, with 255 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 76.7% on time across 487 flights.

Republic on MYR to EWR did not run the same all year. Its best quarter was Apr–Jun 2026 at 85.5% on time and its weakest Jul–Sep 2025 at 61.5%, a swing of 24 points on roughly 122 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

Across the week, Tuesday is the strongest day at 79.7% on time and Friday the weakest at 72.7%. 7 points is a smaller lever than departure hour, but it is free.

Delay causes

Why Republic runs late on this route

One category carries most of the weight here. National Airspace System accounts for 47% of the 9,415 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
27%
Carrier

Extreme weather
2%

47% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 4,411 minutes out of 9,415, against a national NAS share of 21%. The split is drawn from 9,415 reported delay minutes.

Cancellations run at 5.54%, against 1.81% nationally. That is roughly 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

8.7% 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 an hour and a half, which a normal layover absorbs.

The 550 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

The return leg is a different operation and performs like one: it runs 82.1% on time across 487 flights, 5 points above this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 5 points of difference.

One caution: this is a thin sample. 487 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 EWR

Put together: the delay figures matter less here than the 5.54% cancellation rate. A late arrival costs you an hour and a half; a cancelled flight costs you the day. Book the 11am–2pm departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 459 completed flights over 12 months sit behind that.
