Springfield to Chicago

What the Data Says About SGF to ORD

The Springfield to Chicago corridor (SGF → ORD) covers roughly 438 miles and is served by 4 carriers, based on Bureau of Transportation Statistics reporting. Across 8,258 flights in the dataset, this route posts a 80.3% on-time rate with an average delay of 99.3 minutes when flights run late. Over the most recent 24 months of BTS data, 3,256 flights were recorded on this pairing — 48 cancelled (1.5%) and 9 diverted (0.3%). 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 8,258 total flights analyzed, the 80.3% on-time figure is statistically meaningful rather than a small-sample fluke. The 99.3-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 2024 posted the best performance on this corridor at 90% on-time, while Dec 2025 came in at 59% on-time — a 32-point gap between best and worst recent month. For travelers evaluating the SGF to ORD route, the combination of a 80.3% on-time rate, 99.3-minute average delay, 1.5% recent cancellation rate, and 4 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
