CLT to CHS against comparable routes
July 2023 – July 2026| Measure | This route | Compared with | Them | Gap | Flights behind it |
|---|---|---|---|---|---|
| Hour: 3 PM departures | 83.0% | routes of similar length | 72.1% | +10.9 pts | 141 here, 12,730 there |

Each comparison pools the flights of other routes, with this route’s own left out. Similar length means within 15% of this route’s 168 miles, with at least 5 such routes. A bucket is set against the most comparable group that has enough flights: similar length, then the same origin (at least 3 routes), then all other routes. Hours, weekdays and months appear only where both sides have 120 completed flights, and airlines where both have 600. The gap must be at least 2 points and 2 standard errors, and only the largest gap each way is kept per measure. These are differences in the flights counted, not causes.
CLT to CHS in context

Share of cancellations
Of 131 cancelled departures carrying a reason code.
What each reason means
Conditions the carrier judged severe enough to stop the flight: a blizzard, a hurricane, a line of thunderstorms.
115 cancellations, 87.8% of the total.
Crew, maintenance, aircraft cleaning, baggage or fueling: what BTS counts as within the carrier’s own control.
11 cancellations, 8.4% of the total.
Airport capacity, air traffic control flow programs, heavy traffic and ordinary bad weather. A system decision, not the airline’s.
5 cancellations, 3.8% of the total.
A terminal evacuation, a security breach, screening equipment failure, or screening queues over 29 minutes.
0 cancellations, 0.0% of the total.
Reason codes are the operating airline’s own filing with US DOT, not an independent finding of fault. Ordinary bad weather is filed under air traffic, so weather’s full share is larger than its bar.
131 coded cancellations were recorded on CLT → CHS; the section appears from 50.

Will your connection be tight enough?
Layovers at CHS after arriving from CLT.
| Connection time | Chance of missing | Reads as |
|---|---|---|
| 30 min | 41% | Likely to miss |
| 45 min | 23% | High risk |
| 60 min | 16% | High risk |
| 90 min | 8.4% | Some risk |
| 120 min | 5.1% | Some risk |
This is one leg of a connection. Gate changes and the next flight's own schedule matter too. And a connection can fail before delay is even the question — this route cancels 1.59% of the time and diverts 0.12% of the time, which a late arrival never shows up in.
Chance of missing is the share of 8,111 arrivals on this route that landed later than the connection time less 30 minutes to reach the next gate.
The worst tenth of arrivals on this route land at least 52 minutes late (90th-percentile gate arrival delay), over 8,252 operations.

Why CLT → CHS runs late
July 2023 – July 2026
the inbound aircraft was late, so this flight started late

airspace and airport capacity, including weather-driven flow control
