Wilmington to New York

What the Data Says About ILM to LGA

The Wilmington to New York corridor (ILM → LGA) covers roughly 500 miles and is served by 4 carriers, based on Bureau of Transportation Statistics reporting. Across 6,699 flights in the dataset, this route posts a 83.1% on-time rate with an average delay of 84.6 minutes when flights run late. Over the most recent 24 months of BTS data, 2,657 flights were recorded on this pairing — 99 cancelled (3.7%) and 6 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 4 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 6,699 total flights analyzed, the 83.1% on-time figure is statistically meaningful rather than a small-sample fluke. The 84.6-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, Sep 2025 posted the best performance on this corridor at 94% on-time, while Dec 2025 came in at 69% on-time — a 25-point gap between best and worst recent month. For travelers evaluating the ILM to LGA route, the combination of a 83.1% on-time rate, 84.6-minute average delay, 3.7% recent cancellation rate, and 4 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
