Republic on CHS to JFK lands a B−, level with the national rate of 77.3%. Roughly one flight in five arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That rests on 150 flights, with a median arrival 10 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate Republic on CHS to JFK from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

These figures cover 150 flights between September 2025 and August 2026. The median arrival is 10 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 CHS to JFK
Republic flew 150 of the 789 flights on CHS to JFK, about 19% of it. Its 77.9% on time is 4 points better than the route as a whole, which runs 73.5%. Ranked by on-time rate it is number two of three carriers on the route, where the range runs from Delta at 100.0% to JetBlue at 72.5%. 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 150 flights.
- 5am–8am62 flights83.6%
- 8am–11am—
- 11am–2pm76 flights75.7%
- 2pm–5pm—
- 5pm–8pm12 flights—
- 8pm–5am—
Scale runs 65% to 90%. 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 75.7% on time against 83.6% for 5am–8am. 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 76 flights scheduled in it.

Split by quarter, Republic on CHS to JFK logged 21 flights in Oct–Dec 2025 and 129 flights in Jan–Mar 2026. Fewer than three of those quarters carried the 30 completed flights this site needs before printing a rate, so the 77.9% annual figure is the one to use.

| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 24 February 2026 | 4 hours 31 minutes | National Airspace System |
| 27 January 2026 | 3 hours 22 minutes | Carrier |

Delay causes
Why Republic runs late on this route
Carrier accounts for 43% of the 2,137 delay minutes carriers reported here, and the remaining four split what is left.
- 43%Carrier
- 31%National Airspace System
- 18%Late-arriving aircraft
- 8%Extreme weather
The largest share of delay minutes, 43%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 920 of the 2,137 delay minutes reported here. The split is drawn from 2,137 reported delay minutes.
Cancellations run at 9.33%, against 1.89% nationally. That is about one flight in ten 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
7.4% of arrivals land an hour or more late, close to the national 8.3%, so 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 636 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 80.3% on time across 151 flights, within 2 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. 150 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 JFK
Put together: the delay figures matter less here than the 9.33% cancellation rate. A late arrival costs you a little over an hour; 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. 136 completed flights over 12 months sit behind that.
