Boston to Wilmington

What the Data Says About BOS to ILM

The Boston to Wilmington corridor (BOS → ILM) covers roughly 672 miles and is served by 7 carriers, based on Bureau of Transportation Statistics reporting. Across 965 flights in the dataset, this route posts a 86.4% on-time rate with an average delay of 61.6 minutes when flights run late. Over the most recent 24 months of BTS data, 965 flights were recorded on this pairing — 7 cancelled (0.7%) and 0 diverted (0.0%). Those baseline metrics tell you what to expect before you book.

Having 7 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 965 total flights analyzed, the 86.4% on-time figure is statistically meaningful rather than a small-sample fluke. The 61.6-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, Jun 2025 posted the best performance on this corridor at 93% on-time, while Oct 2025 came in at 81% on-time — a 12-point gap between best and worst recent month. For travelers evaluating the BOS to ILM route, the combination of a 86.4% on-time rate, 61.6-minute average delay, 0.7% recent cancellation rate, and 7 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
