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

Republic on EWR to CHS lands a B−, 3 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 a little over an hour on average. That is a workable record, not a spotless one. That rests on 285 flights, with a median arrival 11 minutes early.

The US average over the same twelve months is 77.6%, so there is little to separate Republic on EWR to CHS from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

These figures cover 285 flights between July 2025 and June 2026. The median arrival is 11 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 EWR to CHS

Republic flew 285 of the 1,362 flights on EWR to CHS, about 21% of it. Its 80.2% on time is about level with the route as a whole at 79.8%. Ranked by on-time rate it is number two of three carriers on the route, where the range runs from United at 81.7% to Spirit at 73.3%. 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 21 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–8am41 flights84.6%
8am–11am6 flights—
11am–2pm96 flights87.1%
2pm–5pm54 flights85.7%
5pm–8pm3 flights—
8pm–5am85 flights65.8%

Scale runs 55% to 95%. Rows with fewer than 30 flights show a dash.

The best window here is not the first bank but the 11am–2pm slot at 87.1% on time, ahead of 8pm–5am at 65.8%. 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 11am–2pm window is the busiest, with 96 flights scheduled in it.

Across the year

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 80.2% on time across 285 flights.

Split by quarter, Republic on EWR to CHS logged 174 flights in Jul–Sep 2025, 26 flights in Oct–Dec 2025, 65 flights in Jan–Mar 2026 and 20 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 80.2% annual figure is the one to use.

Across the week, Saturday is the strongest day at 84.0% on time and Friday the weakest at 69.7%. 14 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. Late-arriving aircraft accounts for 51% of the 4,204 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.

51% 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 4,204 reported delay minutes here, that single category outweighs weather by 51 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 4,204 reported delay minutes.

Cancellations run at 7.37%, 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

7.6% 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 a little over an hour, which a normal layover absorbs.

The 628 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 runs 81.6% on time across 283 flights, within about a point 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. 285 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 EWR to CHS

Put together: the delay figures matter less here than the 7.37% cancellation rate. A late arrival costs you a little over an hour; 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. 262 completed flights over 12 months sit behind that.
