Wichita to St. Louis

What the Data Says About ICT to STL

The Wichita to St. Louis corridor (ICT → STL) covers roughly 392 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 3,659 flights in the dataset, this route posts a 90.5% on-time rate with an average delay of 63.6 minutes when flights run late. Over the most recent 24 months of BTS data, 1,363 flights were recorded on this pairing — 9 cancelled (0.7%) and 0 diverted (0.0%). 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 3,659 total flights analyzed, the 90.5% on-time figure is statistically meaningful rather than a small-sample fluke. The 63.6-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, Oct 2024 posted the best performance on this corridor at 98% on-time, while Jun 2025 came in at 79% on-time — a 20-point gap between best and worst recent month. For travelers evaluating the ICT to STL route, the combination of a 90.5% on-time rate, 63.6-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.
