What the Data Says About SHD to IAD

The Staunton to Washington corridor (SHD → IAD) covers roughly 91 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 701 flights in the dataset, this route posts a 88.4% on-time rate with an average delay of 172.9 minutes when flights run late. Over the most recent 24 months of BTS data, 701 flights were recorded on this pairing — 20 cancelled (2.9%) 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 701 total flights analyzed, the 88.4% on-time figure is statistically meaningful rather than a small-sample fluke. The 172.9-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, Mar 2020 posted the best performance on this corridor at 92% on-time, while Feb 2020 came in at 90% on-time — a 2-point gap between best and worst recent month. For travelers evaluating the SHD to IAD route, the combination of a 88.4% on-time rate, 172.9-minute average delay, 2.9% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
