Las Vegas to Chicago

What the Data Says About LAS to ORD

The Las Vegas to Chicago corridor (LAS → ORD) covers roughly 1,514 miles and is served by 30 carriers, based on Bureau of Transportation Statistics reporting. Across 28,710 flights in the dataset, this route posts a 80.7% on-time rate with an average delay of 75.9 minutes when flights run late. Over the most recent 24 months of BTS data, 10,599 flights were recorded on this pairing — 126 cancelled (1.2%) and 39 diverted (0.4%). Those baseline metrics tell you what to expect before you book.

Having 30 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 28,710 total flights analyzed, the 80.7% on-time figure is statistically meaningful rather than a small-sample fluke. The 75.9-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 90% on-time, while Jul 2024 came in at 69% on-time — a 21-point gap between best and worst recent month. For travelers evaluating the LAS to ORD route, the combination of a 80.7% on-time rate, 75.9-minute average delay, 1.2% recent cancellation rate, and 30 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
