Grand Junction to Denver

What the Data Says About GJT to DEN

The Grand Junction to Denver corridor (GJT → DEN) covers roughly 212 miles and is served by 9 carriers, based on Bureau of Transportation Statistics reporting. Across 8,513 flights in the dataset, this route posts a 79.3% on-time rate with an average delay of 92.5 minutes when flights run late. Over the most recent 24 months of BTS data, 3,928 flights were recorded on this pairing — 51 cancelled (1.3%) and 5 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 8,513 total flights analyzed, the 79.3% on-time figure is statistically meaningful rather than a small-sample fluke. The 92.5-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, Oct 2024 posted the best performance on this corridor at 93% on-time, while Jun 2025 came in at 59% on-time — a 34-point gap between best and worst recent month. For travelers evaluating the GJT to DEN route, the combination of a 79.3% on-time rate, 92.5-minute average delay, 1.3% recent cancellation rate, and 9 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
