Lexington to Chicago

What the Data Says About LEX to ORD

The Lexington to Chicago corridor (LEX → ORD) covers roughly 323 miles and is served by 17 carriers, based on Bureau of Transportation Statistics reporting. Across 6,918 flights in the dataset, this route posts a 80.2% on-time rate with an average delay of 82.3 minutes when flights run late. Over the most recent 24 months of BTS data, 3,153 flights were recorded on this pairing — 49 cancelled (1.6%) and 3 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 17 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 6,918 total flights analyzed, the 80.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 82.3-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, Apr 2024 posted the best performance on this corridor at 92% on-time, while Dec 2025 came in at 52% on-time — a 41-point gap between best and worst recent month. For travelers evaluating the LEX to ORD route, the combination of a 80.2% on-time rate, 82.3-minute average delay, 1.6% recent cancellation rate, and 17 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
