Washington to Grand Rapids

What the Data Says About DCA to GRR

The Washington to Grand Rapids corridor (DCA → GRR) covers roughly 524 miles and is served by 8 carriers, based on Bureau of Transportation Statistics reporting. Across 3,272 flights in the dataset, this route posts a 76.3% on-time rate with an average delay of 75.5 minutes when flights run late. Over the most recent 24 months of BTS data, 1,391 flights were recorded on this pairing — 64 cancelled (4.6%) and 5 diverted (0.4%). Those baseline metrics tell you what to expect before you book.

Having 8 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 3,272 total flights analyzed, the 76.3% on-time figure is statistically meaningful rather than a small-sample fluke. The 75.5-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 83% on-time, while Dec 2025 came in at 43% on-time — a 40-point gap between best and worst recent month. For travelers evaluating the DCA to GRR route, the combination of a 76.3% on-time rate, 75.5-minute average delay, 4.6% recent cancellation rate, and 8 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
