Devils Lake to Denver

What the Data Says About DVL to DEN

The Devils Lake to Denver corridor (DVL → DEN) covers roughly 638 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 1,394 flights in the dataset, this route posts a 77% on-time rate with an average delay of 137.2 minutes when flights run late. Over the most recent 24 months of BTS data, 900 flights were recorded on this pairing — 25 cancelled (2.8%) and 3 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 1,394 total flights analyzed, the 77% on-time figure is statistically meaningful rather than a small-sample fluke. The 137.2-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 2024 posted the best performance on this corridor at 85% on-time, while Aug 2025 came in at 58% on-time — a 26-point gap between best and worst recent month. For travelers evaluating the DVL to DEN route, the combination of a 77% on-time rate, 137.2-minute average delay, 2.8% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
