Charlotte to Chattanooga

What the Data Says About CLT to CHA

The Charlotte to Chattanooga corridor (CLT → CHA) covers roughly 241 miles and is served by 6 carriers, based on Bureau of Transportation Statistics reporting. Across 4,399 flights in the dataset, this route posts a 81.3% on-time rate with an average delay of 67.2 minutes when flights run late. Over the most recent 24 months of BTS data, 1,580 flights were recorded on this pairing — 28 cancelled (1.8%) and 3 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 6 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 4,399 total flights analyzed, the 81.3% on-time figure is statistically meaningful rather than a small-sample fluke. The 67.2-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 2025 posted the best performance on this corridor at 95% on-time, while Sep 2024 came in at 64% on-time — a 31-point gap between best and worst recent month. For travelers evaluating the CLT to CHA route, the combination of a 81.3% on-time rate, 67.2-minute average delay, 1.8% recent cancellation rate, and 6 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
