Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with Spirit Airlines.
Spirit on EWR to CHS sits in the middle of the pack with a C−. Close to three flights in four arrive on time by the DOT's definition, 3 points worse than the national rate of 77.3%. The late ones land about an hour behind schedule. That rests on 235 flights, with a median arrival 7 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate Spirit on EWR to CHS from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Carrier by carrier
Spirit against every carrier on EWR to CHS
Spirit flew 235 of the 1,321 flights on EWR to CHS, about 18% of it. Its 73.9% on time is 5 points worse than the route as a whole, which runs 78.9%. Ranked by on-time rate it is last 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 Spirit runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 24 points, against half a point between the best and worst carrier.
- 5am–8am26 flights—
- 8am–11am54 flights72.5%
- 11am–2pm32 flights53.1%
- 2pm–5pm114 flights77.4%
- 5pm–8pm9 flights—
- 8pm–5am—
Scale runs 45% to 85%. 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 53.1% on time against 77.4% for 2pm–5pm. 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 2pm–5pm window is the busiest, with 114 flights scheduled in it.

Split by quarter, Spirit on EWR to CHS logged 17 flights in Jul–Sep 2025, 118 flights in Oct–Dec 2025, 76 flights in Jan–Mar 2026 and 24 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 73.9% annual figure is the one to use.
Across the week, Thursday is the strongest day at 85.7% on time and Sunday the weakest at 63.6%, a spread of 22 points.

Delay causes
Why Spirit 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 3,812 reported delay minutes.
- 40%National Airspace System
- 39%Carrier
- 18%Late-arriving aircraft
- 2%Security
- 0%Extreme weather
40% 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 1,512 minutes out of 3,812, against a national NAS share of 21%. The split is drawn from 3,812 reported delay minutes.
The largest share of delay minutes, 39%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,503 of the 3,812 delay minutes reported here.
Cancellations run at 5.53%, 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
10.8% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection 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.
The return leg is a different operation and performs like one: it runs 61.4% on time across 234 flights, 13 points below 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 13 points of difference.
One caution: this is a thin sample. 235 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 Spirit on EWR to CHS
Put together: the delay figures matter less here than the 5.53% cancellation rate. A late arrival costs you about an hour; a cancelled flight costs you the day. Book the 2pm–5pm departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 222 completed flights over 12 months sit behind that.
