New York to Charleston

What the Data Says About LGA to CHS

The New York to Charleston corridor (LGA → CHS) covers roughly 641 miles and is served by 27 carriers, based on Bureau of Transportation Statistics reporting. Across 7,933 flights in the dataset, this route posts a 78.6% on-time rate with an average delay of 75.3 minutes when flights run late. Over the most recent 24 months of BTS data, 3,028 flights were recorded on this pairing — 91 cancelled (3.0%) and 5 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 27 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 7,933 total flights analyzed, the 78.6% on-time figure is statistically meaningful rather than a small-sample fluke. The 75.3-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, Sep 2024 posted the best performance on this corridor at 91% on-time, while Dec 2025 came in at 56% on-time — a 35-point gap between best and worst recent month. For travelers evaluating the LGA to CHS route, the combination of a 78.6% on-time rate, 75.3-minute average delay, 3.0% recent cancellation rate, and 27 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
