What the Data Says About PBG to IAD

The Plattsburgh to Washington corridor (PBG → IAD) covers roughly 444 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 1,286 flights in the dataset, this route posts a 83.9% on-time rate with an average delay of 138.9 minutes when flights run late. Over the most recent 24 months of BTS data, 1,130 flights were recorded on this pairing — 42 cancelled (3.7%) and 3 diverted (0.3%). 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 1,286 total flights analyzed, the 83.9% on-time figure is statistically meaningful rather than a small-sample fluke. The 138.9-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, Aug 2020 posted the best performance on this corridor at 94% on-time, while Dec 2021 came in at 69% on-time — a 26-point gap between best and worst recent month. For travelers evaluating the PBG to IAD route, the combination of a 83.9% on-time rate, 138.9-minute average delay, 3.7% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
