Las Vegas to Chicago

What the Data Says About LAS to MDW

The Las Vegas to Chicago corridor (LAS → MDW) covers roughly 1,521 miles and is served by 5 carriers, based on Bureau of Transportation Statistics reporting. Across 16,976 flights in the dataset, this route posts a 77.4% on-time rate with an average delay of 55.3 minutes when flights run late. Over the most recent 24 months of BTS data, 5,739 flights were recorded on this pairing — 50 cancelled (0.9%) and 32 diverted (0.6%). 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 16,976 total flights analyzed, the 77.4% on-time figure is statistically meaningful rather than a small-sample fluke. The 55.3-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, Nov 2024 posted the best performance on this corridor at 91% on-time, while Jul 2024 came in at 61% on-time — a 30-point gap between best and worst recent month. For travelers evaluating the LAS to MDW route, the combination of a 77.4% on-time rate, 55.3-minute average delay, 0.9% recent cancellation rate, and 5 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
