Madison to Atlanta

What the Data Says About MSN to ATL

The Madison to Atlanta corridor (MSN → ATL) covers roughly 707 miles and is served by 5 carriers, based on Bureau of Transportation Statistics reporting. Across 5,757 flights in the dataset, this route posts a 91.4% on-time rate with an average delay of 98.4 minutes when flights run late. Over the most recent 24 months of BTS data, 2,026 flights were recorded on this pairing — 24 cancelled (1.2%) and 6 diverted (0.3%). Those baseline metrics tell you what to expect before you book.

Having 5 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 91.4% on-time figure is statistically meaningful rather than a small-sample fluke. The 98.4-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 2025 posted the best performance on this corridor at 99% on-time, while Jul 2024 came in at 76% on-time — a 22-point gap between best and worst recent month. For travelers evaluating the MSN to ATL route, the combination of a 91.4% on-time rate, 98.4-minute average delay, 1.2% recent cancellation rate, and 5 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
