What the Data Says About CMH to CLT

The Columbus to Charlotte corridor (CMH → CLT) covers roughly 347 miles and is served by 16 carriers, based on Bureau of Transportation Statistics reporting. Across 12,059 flights in the dataset, this route posts a 83.7% on-time rate with an average delay of 90.0 minutes when flights run late. Over the most recent 24 months of BTS data, 4,044 flights were recorded on this pairing — 50 cancelled (1.2%) and 5 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 16 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 12,059 total flights analyzed, the 83.7% on-time figure is statistically meaningful rather than a small-sample fluke. The 90.0-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 92% on-time, while May 2024 came in at 65% on-time — a 27-point gap between best and worst recent month. For travelers evaluating the CMH to CLT route, the combination of a 83.7% on-time rate, 90.0-minute average delay, 1.2% recent cancellation rate, and 16 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
