Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Republic Airways.
Republic on CHS to EWR lands a B−, 4 points better than the national rate of 77.6%. Roughly one flight in five arrives 15 minutes late or worse, and those flights are late by close to two hours on average. That is a workable record, not a spotless one. That rests on 283 flights, with a median arrival 13 minutes early.
Set against the rest of the country, Republic's CHS to EWR record is 4 points better than the US average of 77.6%. That gap is worth roughly 40 fewer late arrivals for every thousand flights.

These figures cover 283 flights between July 2025 and June 2026. Beyond the headline rate, 10.0% 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 CHS to EWR
Republic flew 283 of the 1,362 flights on CHS to EWR, about 21% of it. Its 81.6% on time is 3 points better than the route as a whole, which runs 78.9%. Ranked by on-time rate it is number two of three carriers on the route, where the range runs from United at 83.4% to Spirit at 62.6%. 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 22 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–11am—
- 11am–2pm46 flights82.2%
- 2pm–5pm97 flights69.4%
- 5pm–8pm54 flights85.1%
- 8pm–5am3 flights—
Scale runs 60% to 95%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 91.4% of the time, against 69.4% for the afternoon window. That is 22 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 2pm–5pm window is the busiest, with 97 flights scheduled in it.
Across the year

- Jul–Sep 2025175 flights79.6%

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 81.6% on time across 283 flights.
Split by quarter, Republic on CHS to EWR logged 175 flights in Jul–Sep 2025, 26 flights in Oct–Dec 2025, 64 flights in Jan–Mar 2026 and 18 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 81.6% annual figure is the one to use.
Across the week, Monday is the strongest day at 90.0% on time and Thursday the weakest at 69.7%. 20 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 54% of the 4,824 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.
- 54%National Airspace System
- 24%Late-arriving aircraft
- 17%Carrier
- 5%Extreme weather
54% 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 2,611 minutes out of 4,824, against a national NAS share of 21%. The split is drawn from 4,824 reported delay minutes.
Cancellations run at 6.71%, against 1.81% nationally. That is about 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
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 10.0% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.
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 80.2% on time across 285 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. 283 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 CHS to EWR
Put together: the delay figures matter less here than the 6.71% cancellation rate. A late arrival costs you close to two hours; a cancelled flight costs you the day. Book the 5am–8am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 261 completed flights over 12 months sit behind that.
