Denver to Lewiston

What the Data Says About DEN to LWS

The Denver to Lewiston corridor (DEN → LWS) covers roughly 768 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 1,103 flights in the dataset, this route posts a 85.2% on-time rate with an average delay of 69.9 minutes when flights run late. Over the most recent 24 months of BTS data, 736 flights were recorded on this pairing — 6 cancelled (0.8%) and 2 diverted (0.3%). Those baseline metrics tell you what to expect before you book.

Having 1 carrier on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 1,103 total flights analyzed, the 85.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 69.9-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).

Monthly performance varies, so review the monthly table above to see specific periods. For travelers evaluating the DEN to LWS route, the combination of a 85.2% on-time rate, 69.9-minute average delay, 0.8% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
