What the Data Says About SGF to DEN

The Springfield to Denver corridor (SGF → DEN) covers roughly 637 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 4,071 flights in the dataset, this route posts a 80.1% on-time rate with an average delay of 99.0 minutes when flights run late. Over the most recent 24 months of BTS data, 2,254 flights were recorded on this pairing — 15 cancelled (0.7%) and 6 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 4,071 total flights analyzed, the 80.1% on-time figure is statistically meaningful rather than a small-sample fluke. The 99.0-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, Nov 2025 posted the best performance on this corridor at 98% on-time, while Jun 2025 came in at 64% on-time — a 34-point gap between best and worst recent month. For travelers evaluating the SGF to DEN route, the combination of a 80.1% on-time rate, 99.0-minute average delay, 0.7% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
