Charleston to Charlotte

What the Data Says About CHS to CLT

The Charleston to Charlotte corridor (CHS → CLT) covers roughly 168 miles and is served by 11 carriers, based on Bureau of Transportation Statistics reporting. Across 15,331 flights in the dataset, this route posts a 84.6% on-time rate with an average delay of 92.7 minutes when flights run late. Over the most recent 24 months of BTS data, 5,541 flights were recorded on this pairing — 94 cancelled (1.7%) and 3 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 11 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 15,331 total flights analyzed, the 84.6% on-time figure is statistically meaningful rather than a small-sample fluke. The 92.7-minute average delay applies only to flights that actually ran late, so it is not the average wait across all departures — the majority of flights on this route depart on time under the BTS definition of a delay (15+ minutes past schedule).

Looking at recent months, Feb 2024 posted the best performance on this corridor at 93% on-time, while Jul 2024 came in at 68% on-time — a 25-point gap between best and worst recent month. For travelers evaluating the CHS to CLT route, the combination of a 84.6% on-time rate, 92.7-minute average delay, 1.7% recent cancellation rate, and 11 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
