Atlanta to Mobile

What the Data Says About ATL to MOB

The Atlanta to Mobile corridor (ATL → MOB) covers roughly 302 miles and is served by 13 carriers, based on Bureau of Transportation Statistics reporting. Across 7,902 flights in the dataset, this route posts a 87% on-time rate with an average delay of 73.8 minutes when flights run late. Over the most recent 24 months of BTS data, 2,682 flights were recorded on this pairing — 28 cancelled (1.0%) and 5 diverted (0.2%). 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 7,902 total flights analyzed, the 87% on-time figure is statistically meaningful rather than a small-sample fluke. The 73.8-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 2023 posted the best performance on this corridor at 97% on-time, while Jun 2025 came in at 54% on-time — a 43-point gap between best and worst recent month. For travelers evaluating the ATL to MOB route, the combination of a 87% on-time rate, 73.8-minute average delay, 1.0% recent cancellation rate, and 13 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
