What the Data Says About IAD to PBG

The Washington to Plattsburgh corridor (IAD → PBG) covers roughly 444 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 1,256 flights in the dataset, this route posts a 82.6% on-time rate with an average delay of 162.1 minutes when flights run late. Over the most recent 24 months of BTS data, 1,153 flights were recorded on this pairing — 45 cancelled (3.9%) and 7 diverted (0.6%). 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 1,256 total flights analyzed, the 82.6% on-time figure is statistically meaningful rather than a small-sample fluke. The 162.1-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 2020 posted the best performance on this corridor at 96% on-time, while Jul 2021 came in at 60% on-time — a 36-point gap between best and worst recent month. For travelers evaluating the IAD to PBG route, the combination of a 82.6% on-time rate, 162.1-minute average delay, 3.9% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
