Hilton Head to Atlanta

What the Data Says About HHH to ATL

The Hilton Head to Atlanta corridor (HHH → ATL) covers roughly 238 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 2,895 flights in the dataset, this route posts a 86.3% on-time rate with an average delay of 95.3 minutes when flights run late. Over the most recent 24 months of BTS data, 976 flights were recorded on this pairing — 12 cancelled (1.2%) and 5 diverted (0.5%). Those baseline metrics tell you what to expect before you book.

Having 1 carrier on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 2,895 total flights analyzed, the 86.3% on-time figure is statistically meaningful rather than a small-sample fluke. The 95.3-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, Oct 2022 posted the best performance on this corridor at 98% on-time, while May 2022 came in at 81% on-time — a 18-point gap between best and worst recent month. For travelers evaluating the HHH to ATL route, the combination of a 86.3% on-time rate, 95.3-minute average delay, 1.2% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
