Charlotte to Hilton Head

What the Data Says About CLT to HHH

The Charlotte to Hilton Head corridor (CLT → HHH) covers roughly 207 miles and is served by 4 carriers, based on Bureau of Transportation Statistics reporting. Across 6,270 flights in the dataset, this route posts a 83.7% on-time rate with an average delay of 61.8 minutes when flights run late. Over the most recent 24 months of BTS data, 2,075 flights were recorded on this pairing — 26 cancelled (1.3%) and 14 diverted (0.7%). Those baseline metrics tell you what to expect before you book.

Having 4 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 6,270 total flights analyzed, the 83.7% on-time figure is statistically meaningful rather than a small-sample fluke. The 61.8-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, Sep 2025 posted the best performance on this corridor at 96% on-time, while May 2024 came in at 62% on-time — a 33-point gap between best and worst recent month. For travelers evaluating the CLT to HHH route, the combination of a 83.7% on-time rate, 61.8-minute average delay, 1.3% recent cancellation rate, and 4 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
