Carrier by carrier
Spirit against every carrier on CHS to EWR
Spirit flew 234 of the 1,320 flights on CHS to EWR, about 18% of it. Its 61.4% on time is 18 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 84.8% to Spirit at 61.4%. 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 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 234 flights.

- 8am–11am26 flights—
- 11am–2pm54 flights64.7%

Scale runs 50% to 70%. Rows with fewer than 30 flights show a dash.
The best window here is not the first bank but the 11am–2pm slot at 64.7% on time, ahead of 5pm–8pm at 58.7%. 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 5pm–8pm window is the busiest, with 112 flights scheduled in it.

Delay causes
Why Spirit runs late on this route
National Airspace System accounts for 64% of the 6,313 delay minutes carriers reported here, and the remaining four split what is left.
- 64%National Airspace System
- 28%Late-arriving aircraft
- 8%Carrier
- 0%Security
64% 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 4,060 minutes out of 6,313, against a national NAS share of 21%. The split is drawn from 6,313 reported delay minutes.
Cancellations run at 5.98%, against 1.89% 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
18.6% 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 73.9% on time across 235 flights, 13 points above 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. 234 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 CHS to EWR
Put together: the delay figures matter less here than the 5.98% 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. 220 completed flights over 12 months sit behind that.
