Spokane to Las Vegas

What the Data Says About GEG to LAS

The Spokane to Las Vegas corridor (GEG → LAS) covers roughly 806 miles and is served by 9 carriers, based on Bureau of Transportation Statistics reporting. Across 4,967 flights in the dataset, this route posts a 83.2% on-time rate with an average delay of 58.5 minutes when flights run late. Over the most recent 24 months of BTS data, 1,608 flights were recorded on this pairing — 3 cancelled (0.2%) and 1 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 9 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 4,967 total flights analyzed, the 83.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 58.5-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 2025 posted the best performance on this corridor at 96% on-time, while Jul 2024 came in at 71% on-time — a 25-point gap between best and worst recent month. For travelers evaluating the GEG to LAS route, the combination of a 83.2% on-time rate, 58.5-minute average delay, 0.2% recent cancellation rate, and 9 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
