Milwaukee to Atlanta

What the Data Says About MKE to ATL

The Milwaukee to Atlanta corridor (MKE → ATL) covers roughly 669 miles and is served by 4 carriers, based on Bureau of Transportation Statistics reporting. Across 13,271 flights in the dataset, this route posts a 89.2% on-time rate with an average delay of 76.0 minutes when flights run late. Over the most recent 24 months of BTS data, 4,744 flights were recorded on this pairing — 52 cancelled (1.1%) and 13 diverted (0.3%). 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 13,271 total flights analyzed, the 89.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 76.0-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, Oct 2024 posted the best performance on this corridor at 96% on-time, while Jan 2024 came in at 71% on-time — a 25-point gap between best and worst recent month. For travelers evaluating the MKE to ATL route, the combination of a 89.2% on-time rate, 76.0-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.
