Detroit to Lexington

What the Data Says About DTW to LEX

The Detroit to Lexington corridor (DTW → LEX) covers roughly 296 miles and is served by 11 carriers, based on Bureau of Transportation Statistics reporting. Across 5,054 flights in the dataset, this route posts a 87.4% on-time rate with an average delay of 82.0 minutes when flights run late. Over the most recent 24 months of BTS data, 1,619 flights were recorded on this pairing — 12 cancelled (0.7%) and 3 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 11 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 5,054 total flights analyzed, the 87.4% on-time figure is statistically meaningful rather than a small-sample fluke. The 82.0-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, Sep 2024 posted the best performance on this corridor at 96% on-time, while Jul 2025 came in at 60% on-time — a 37-point gap between best and worst recent month. For travelers evaluating the DTW to LEX route, the combination of a 87.4% on-time rate, 82.0-minute average delay, 0.7% recent cancellation rate, and 11 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
