Springfield to Dallas/Fort Worth

What the Data Says About SPI to DFW

The Springfield to Dallas/Fort Worth corridor (SPI → DFW) covers roughly 630 miles and is served by 4 carriers, based on Bureau of Transportation Statistics reporting. Across 2,078 flights in the dataset, this route posts a 80.8% on-time rate with an average delay of 89.3 minutes when flights run late. Over the most recent 24 months of BTS data, 1,344 flights were recorded on this pairing — 33 cancelled (2.5%) and 8 diverted (0.6%). Those baseline metrics tell you what to expect before you book.

Having 4 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 2,078 total flights analyzed, the 80.8% on-time figure is statistically meaningful rather than a small-sample fluke. The 89.3-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, Feb 2022 posted the best performance on this corridor at 89% on-time, while Aug 2022 came in at 65% on-time — a 24-point gap between best and worst recent month. For travelers evaluating the SPI to DFW route, the combination of a 80.8% on-time rate, 89.3-minute average delay, 2.5% recent cancellation rate, and 4 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
