Cincinnati to Washington

What the Data Says About CVG to DCA

The Cincinnati to Washington corridor (CVG → DCA) covers roughly 411 miles and is served by 23 carriers, based on Bureau of Transportation Statistics reporting. Across 8,572 flights in the dataset, this route posts a 79.8% on-time rate with an average delay of 75.8 minutes when flights run late. Over the most recent 24 months of BTS data, 2,892 flights were recorded on this pairing — 86 cancelled (3.0%) and 8 diverted (0.3%). Those baseline metrics tell you what to expect before you book.

Having 23 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 8,572 total flights analyzed, the 79.8% on-time figure is statistically meaningful rather than a small-sample fluke. The 75.8-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, Sep 2024 posted the best performance on this corridor at 85% on-time, while Feb 2025 came in at 49% on-time — a 36-point gap between best and worst recent month. For travelers evaluating the CVG to DCA route, the combination of a 79.8% on-time rate, 75.8-minute average delay, 3.0% recent cancellation rate, and 23 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
