Pittsburgh to Denver

What the Data Says About PIT to DEN

The Pittsburgh to Denver corridor (PIT → DEN) covers roughly 1,290 miles and is served by 12 carriers, based on Bureau of Transportation Statistics reporting. Across 9,100 flights in the dataset, this route posts a 83% on-time rate with an average delay of 63.4 minutes when flights run late. Over the most recent 24 months of BTS data, 3,583 flights were recorded on this pairing — 15 cancelled (0.4%) and 9 diverted (0.3%). Those baseline metrics tell you what to expect before you book.

Having 12 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 9,100 total flights analyzed, the 83% on-time figure is statistically meaningful rather than a small-sample fluke. The 63.4-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, Sep 2024 posted the best performance on this corridor at 94% on-time, while Jun 2025 came in at 68% on-time — a 27-point gap between best and worst recent month. For travelers evaluating the PIT to DEN route, the combination of a 83% on-time rate, 63.4-minute average delay, 0.4% recent cancellation rate, and 12 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
