Detroit to Las Vegas

What the Data Says About DTW to LAS

The Detroit to Las Vegas corridor (DTW → LAS) covers roughly 1,749 miles and is served by 21 carriers, based on Bureau of Transportation Statistics reporting. Across 18,476 flights in the dataset, this route posts a 82.2% on-time rate with an average delay of 63.9 minutes when flights run late. Over the most recent 24 months of BTS data, 6,289 flights were recorded on this pairing — 28 cancelled (0.4%) and 8 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 21 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 18,476 total flights analyzed, the 82.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 63.9-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, May 2025 posted the best performance on this corridor at 90% on-time, while Dec 2025 came in at 66% on-time — a 23-point gap between best and worst recent month. For travelers evaluating the DTW to LAS route, the combination of a 82.2% on-time rate, 63.9-minute average delay, 0.4% recent cancellation rate, and 21 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
