What the Data Says About HHH to LGA

The Hilton Head to New York corridor (HHH → LGA) covers roughly 701 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 817 flights in the dataset, this route posts a 76.6% on-time rate with an average delay of 129.6 minutes when flights run late. Over the most recent 24 months of BTS data, 817 flights were recorded on this pairing — 29 cancelled (3.5%) and 28 diverted (3.4%). 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 817 total flights analyzed, the 76.6% on-time figure is statistically meaningful rather than a small-sample fluke. The 129.6-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, Apr 2021 posted the best performance on this corridor at 92% on-time, while Jul 2021 came in at 75% on-time — a 17-point gap between best and worst recent month. For travelers evaluating the HHH to LGA route, the combination of a 76.6% on-time rate, 129.6-minute average delay, 3.5% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
