Atlanta to Montgomery

What the Data Says About ATL to MGM

The Atlanta to Montgomery corridor (ATL → MGM) covers roughly 147 miles and is served by 4 carriers, based on Bureau of Transportation Statistics reporting. Across 7,806 flights in the dataset, this route posts a 85.9% on-time rate with an average delay of 91.3 minutes when flights run late. Over the most recent 24 months of BTS data, 2,332 flights were recorded on this pairing — 18 cancelled (0.8%) and 4 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 4 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 7,806 total flights analyzed, the 85.9% on-time figure is statistically meaningful rather than a small-sample fluke. The 91.3-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, Oct 2024 posted the best performance on this corridor at 95% on-time, while Jun 2025 came in at 59% on-time — a 36-point gap between best and worst recent month. For travelers evaluating the ATL to MGM route, the combination of a 85.9% on-time rate, 91.3-minute average delay, 0.8% recent cancellation rate, and 4 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
