Atlanta to Columbus

What the Data Says About ATL to CMH

The Atlanta to Columbus corridor (ATL → CMH) covers roughly 447 miles and is served by 13 carriers, based on Bureau of Transportation Statistics reporting. Across 17,426 flights in the dataset, this route posts a 85.4% on-time rate with an average delay of 60.4 minutes when flights run late. Over the most recent 24 months of BTS data, 6,359 flights were recorded on this pairing — 46 cancelled (0.7%) and 6 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 13 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 17,426 total flights analyzed, the 85.4% on-time figure is statistically meaningful rather than a small-sample fluke. The 60.4-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, Oct 2024 posted the best performance on this corridor at 94% on-time, while Jul 2024 came in at 68% on-time — a 27-point gap between best and worst recent month. For travelers evaluating the ATL to CMH route, the combination of a 85.4% on-time rate, 60.4-minute average delay, 0.7% recent cancellation rate, and 13 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
