Chicago to Las Vegas

What the Data Says About MDW to LAS

The Chicago to Las Vegas corridor (MDW → LAS) covers roughly 1,521 miles and is served by 5 carriers, based on Bureau of Transportation Statistics reporting. Across 16,984 flights in the dataset, this route posts a 77.2% on-time rate with an average delay of 58.1 minutes when flights run late. Over the most recent 24 months of BTS data, 5,726 flights were recorded on this pairing — 59 cancelled (1.0%) and 17 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 16,984 total flights analyzed, the 77.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 58.1-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 90% on-time, while May 2024 came in at 68% on-time — a 22-point gap between best and worst recent month. For travelers evaluating the MDW to LAS route, the combination of a 77.2% on-time rate, 58.1-minute average delay, 1.0% recent cancellation rate, and 5 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
