Charleston/Dunbar to Chicago

What the Data Says About CRW to ORD

The Charleston/Dunbar to Chicago corridor (CRW → ORD) covers roughly 416 miles and is served by 2 carriers, based on Bureau of Transportation Statistics reporting. Across 3,019 flights in the dataset, this route posts a 73.1% on-time rate with an average delay of 109.8 minutes when flights run late. Over the most recent 24 months of BTS data, 1,891 flights were recorded on this pairing — 39 cancelled (2.1%) and 10 diverted (0.5%). Those baseline metrics tell you what to expect before you book.

Having 2 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 3,019 total flights analyzed, the 73.1% on-time figure is statistically meaningful rather than a small-sample fluke. The 109.8-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, Apr 2025 posted the best performance on this corridor at 84% on-time, while Dec 2025 came in at 52% on-time — a 33-point gap between best and worst recent month. For travelers evaluating the CRW to ORD route, the combination of a 73.1% on-time rate, 109.8-minute average delay, 2.1% recent cancellation rate, and 2 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
