Every carrier on EWR to CHS, 1,321 flights

These figures cover 165 flights between September 2025 and August 2026. The median arrival is 14 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 165 of the 1,321 flights on EWR to CHS, about 12% of it. Its 85.2% on time is 6 points better than the route as a whole, which runs 78.9%. Ranked by on-time rate it is first of three carriers on the route, where the range runs from Republic at 85.2% to Spirit at 73.9%. 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 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 165 flights.

Scale runs 75% 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 89.7% on time, ahead of 5am–8am at 83.8%. 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 2pm–5pm window is the busiest, with 54 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 85.2% on time across 165 flights.

Split by quarter, Republic on EWR to CHS logged 48 flights in Jul–Sep 2025, 26 flights in Oct–Dec 2025, 65 flights in Jan–Mar 2026, 20 flights in Apr–Jun 2026 and 6 flights in Jul–Sep 2026. Fewer than three of those quarters carried the 30 completed flights this site needs before printing a rate, so the 85.2% annual figure is the one to use.

Arrival by arrival

How late Republic on EWR to CHS runs when it is late

Republic on EWR to CHS often beats the schedule: 76 of 155 completed flights, 49%, arrived 15 minutes or more early. The 23 late arrivals split 10 under half an hour, 6 between 30 and 60 minutes, and 7 an hour or more.

Share of 155 completed flights by arrival against schedule.

A late pushback is often recovered here: of 23 departures that left 15 minutes late or more, 9 still arrived on time. In the other direction, 9 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at CHS.

Delay causes

Why Republic runs late on this route

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 1,367 reported delay minutes.

Carrier
38%
Late-arriving aircraft
34%
National Airspace System
28%
Security
0%

The largest share of delay minutes, 38%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 513 of the 1,367 delay minutes reported here. The split is drawn from 1,367 reported delay minutes.

Cancellations run at 5.45%, against 1.89% 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

Badly late arrivals are rare here: only 4.5% land an hour or more behind schedule, against 8.3% 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.

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.

The return leg runs 84.8% on time across 163 flights, within half 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. 165 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 5.45% cancellation rate. A late arrival costs you about 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. 155 completed flights over 12 months sit behind that.
