Seattle to Reno

What the Data Says About SEA to RNO

The Seattle to Reno corridor (SEA → RNO) covers roughly 564 miles and is served by 11 carriers, based on Bureau of Transportation Statistics reporting. Across 5,488 flights in the dataset, this route posts a 80.1% on-time rate with an average delay of 52.8 minutes when flights run late. Over the most recent 24 months of BTS data, 1,766 flights were recorded on this pairing — 14 cancelled (0.8%) and 4 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 5,488 total flights analyzed, the 80.1% on-time figure is statistically meaningful rather than a small-sample fluke. The 52.8-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, Nov 2024 posted the best performance on this corridor at 94% on-time, while Jul 2025 came in at 62% on-time — a 32-point gap between best and worst recent month. For travelers evaluating the SEA to RNO route, the combination of a 80.1% on-time rate, 52.8-minute average delay, 0.8% recent cancellation rate, and 11 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
