Denver to Pittsburgh

What the Data Says About DEN to PIT

The Denver to Pittsburgh corridor (DEN → PIT) covers roughly 1,290 miles and is served by 12 carriers, based on Bureau of Transportation Statistics reporting. Across 9,133 flights in the dataset, this route posts a 74.5% on-time rate with an average delay of 60.8 minutes when flights run late. Over the most recent 24 months of BTS data, 3,581 flights were recorded on this pairing — 14 cancelled (0.4%) and 3 diverted (0.1%). 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 9,133 total flights analyzed, the 74.5% on-time figure is statistically meaningful rather than a small-sample fluke. The 60.8-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, Sep 2024 posted the best performance on this corridor at 86% on-time, while Jun 2025 came in at 52% on-time — a 34-point gap between best and worst recent month. For travelers evaluating the DEN to PIT route, the combination of a 74.5% on-time rate, 60.8-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.
