Charlotte to Greer

What the Data Says About CLT to GSP

The Charlotte to Greer corridor (CLT → GSP) covers roughly 75 miles and is served by 10 carriers, based on Bureau of Transportation Statistics reporting. Across 14,762 flights in the dataset, this route posts a 80.6% on-time rate with an average delay of 74.9 minutes when flights run late. Over the most recent 24 months of BTS data, 5,417 flights were recorded on this pairing — 74 cancelled (1.4%) and 5 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 10 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 14,762 total flights analyzed, the 80.6% on-time figure is statistically meaningful rather than a small-sample fluke. The 74.9-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, Feb 2024 posted the best performance on this corridor at 93% on-time, while Jun 2025 came in at 55% on-time — a 38-point gap between best and worst recent month. For travelers evaluating the CLT to GSP route, the combination of a 80.6% on-time rate, 74.9-minute average delay, 1.4% recent cancellation rate, and 10 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
