Departure window
When Delta runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 21 points, against half a point between the best and worst carrier.

- 8am–11am1 flights—
- 11am–2pm50 flights82.6%

- 5pm–8pm121 flights66.1%
- 8pm–5am—
Scale runs 55% to 90%. Rows with fewer than 30 flights show a dash.
The best window here is not the first bank but the 11am–2pm slot at 82.6% on time, ahead of 2pm–5pm at 61.8%. 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 223 flights scheduled in it.
Across the year
Delta on CHS to LGA through the year
December is the weak month at 54.9% on time, against 81.8% in September. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. October was the busiest month here, with 63 flights.
Across the week, Saturday is the strongest day at 75.4% on time and Thursday the weakest at 52.1%, a spread of 23 points.

Delay causes
Why Delta runs late on this route
Carrier accounts for 55% of the 22,000 delay minutes carriers reported here, and the remaining four split what is left.
- 55%Carrier
- 24%Late-arriving aircraft
- 20%National Airspace System
- 1%Extreme weather
The largest share of delay minutes, 55%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 12,000 of the 22,000 delay minutes reported here. The split is drawn from 21,565 reported delay minutes.
Cancellations run at 5.57%, 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
19.2% 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 641 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 66.6% on time across 395 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. 395 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 Delta on CHS to LGA
Put together: the delay figures matter less here than the 5.57% cancellation rate. A late arrival costs you about 2.9 hours; 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. 369 completed flights over 12 months sit behind that.
