Atlanta to Madison

What the Data Says About ATL to MSN

The Atlanta to Madison corridor (ATL → MSN) covers roughly 707 miles and is served by 4 carriers, based on Bureau of Transportation Statistics reporting. Across 5,757 flights in the dataset, this route posts a 88.8% on-time rate with an average delay of 65.0 minutes when flights run late. Over the most recent 24 months of BTS data, 2,027 flights were recorded on this pairing — 23 cancelled (1.1%) and 3 diverted (0.1%). 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 5,757 total flights analyzed, the 88.8% on-time figure is statistically meaningful rather than a small-sample fluke. The 65.0-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 94% on-time, while Jun 2025 came in at 64% on-time — a 30-point gap between best and worst recent month. For travelers evaluating the ATL to MSN route, the combination of a 88.8% on-time rate, 65.0-minute average delay, 1.1% recent cancellation rate, and 4 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
