Charlotte to Milwaukee

What the Data Says About CLT to MKE

The Charlotte to Milwaukee corridor (CLT → MKE) covers roughly 651 miles and is served by 8 carriers, based on Bureau of Transportation Statistics reporting. Across 6,616 flights in the dataset, this route posts a 80.4% on-time rate with an average delay of 75.6 minutes when flights run late. Over the most recent 24 months of BTS data, 2,062 flights were recorded on this pairing — 30 cancelled (1.5%) and 6 diverted (0.3%). Those baseline metrics tell you what to expect before you book.

Having 8 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 6,616 total flights analyzed, the 80.4% on-time figure is statistically meaningful rather than a small-sample fluke. The 75.6-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, Sep 2025 posted the best performance on this corridor at 88% on-time, while Jul 2024 came in at 47% on-time — a 41-point gap between best and worst recent month. For travelers evaluating the CLT to MKE route, the combination of a 80.4% on-time rate, 75.6-minute average delay, 1.5% recent cancellation rate, and 8 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
