Atlanta to Las Vegas

What the Data Says About ATL to LAS

The Atlanta to Las Vegas corridor (ATL → LAS) covers roughly 1,747 miles and is served by 17 carriers, based on Bureau of Transportation Statistics reporting. Across 27,285 flights in the dataset, this route posts a 77.8% on-time rate with an average delay of 63.9 minutes when flights run late. Over the most recent 24 months of BTS data, 9,889 flights were recorded on this pairing — 93 cancelled (0.9%) and 16 diverted (0.2%). 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 27,285 total flights analyzed, the 77.8% 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, Oct 2024 posted the best performance on this corridor at 88% on-time, while Jul 2024 came in at 61% on-time — a 27-point gap between best and worst recent month. For travelers evaluating the ATL to LAS route, the combination of a 77.8% on-time rate, 63.9-minute average delay, 0.9% recent cancellation rate, and 17 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
