Charleston to New York

What the Data Says About CHS to LGA

The Charleston to New York corridor (CHS → LGA) covers roughly 641 miles and is served by 26 carriers, based on Bureau of Transportation Statistics reporting. Across 7,936 flights in the dataset, this route posts a 79.2% on-time rate with an average delay of 90.3 minutes when flights run late. Over the most recent 24 months of BTS data, 3,028 flights were recorded on this pairing — 96 cancelled (3.2%) and 7 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 26 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 7,936 total flights analyzed, the 79.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 90.3-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, Nov 2024 posted the best performance on this corridor at 93% on-time, while Jul 2025 came in at 56% on-time — a 37-point gap between best and worst recent month. For travelers evaluating the CHS to LGA route, the combination of a 79.2% on-time rate, 90.3-minute average delay, 3.2% recent cancellation rate, and 26 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
