Milwaukee to Las Vegas

What the Data Says About MKE to LAS

The Milwaukee to Las Vegas corridor (MKE → LAS) covers roughly 1,524 miles and is served by 10 carriers, based on Bureau of Transportation Statistics reporting. Across 7,131 flights in the dataset, this route posts a 83% on-time rate with an average delay of 68.0 minutes when flights run late. Over the most recent 24 months of BTS data, 2,507 flights were recorded on this pairing — 16 cancelled (0.6%) and 2 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 10 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 7,131 total flights analyzed, the 83% on-time figure is statistically meaningful rather than a small-sample fluke. The 68.0-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, Apr 2025 posted the best performance on this corridor at 91% on-time, while Dec 2025 came in at 71% on-time — a 20-point gap between best and worst recent month. For travelers evaluating the MKE to LAS route, the combination of a 83% on-time rate, 68.0-minute average delay, 0.6% recent cancellation rate, and 10 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
