Chattanooga to Atlanta

What the Data Says About CHA to ATL

The Chattanooga to Atlanta corridor (CHA → ATL) covers roughly 106 miles and is served by 12 carriers, based on Bureau of Transportation Statistics reporting. Across 13,428 flights in the dataset, this route posts a 89.3% on-time rate with an average delay of 93.9 minutes when flights run late. Over the most recent 24 months of BTS data, 3,872 flights were recorded on this pairing — 40 cancelled (1.0%) and 0 diverted (0.0%). Those baseline metrics tell you what to expect before you book.

Having 12 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 13,428 total flights analyzed, the 89.3% on-time figure is statistically meaningful rather than a small-sample fluke. The 93.9-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, Oct 2024 posted the best performance on this corridor at 93% on-time, while Jun 2025 came in at 69% on-time — a 24-point gap between best and worst recent month. For travelers evaluating the CHA to ATL route, the combination of a 89.3% on-time rate, 93.9-minute average delay, 1.0% recent cancellation rate, and 12 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
