Charlotte to Columbus

What the Data Says About CLT to CMH

The Charlotte to Columbus corridor (CLT → CMH) covers roughly 347 miles and is served by 17 carriers, based on Bureau of Transportation Statistics reporting. Across 12,068 flights in the dataset, this route posts a 80.4% on-time rate with an average delay of 72.3 minutes when flights run late. Over the most recent 24 months of BTS data, 4,047 flights were recorded on this pairing — 48 cancelled (1.2%) and 1 diverted (0.0%). Those baseline metrics tell you what to expect before you book.

Having 17 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 12,068 total flights analyzed, the 80.4% on-time figure is statistically meaningful rather than a small-sample fluke. The 72.3-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 86% on-time, while Jul 2024 came in at 55% on-time — a 31-point gap between best and worst recent month. For travelers evaluating the CLT to CMH route, the combination of a 80.4% on-time rate, 72.3-minute average delay, 1.2% recent cancellation rate, and 17 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
