Atlanta to Wilmington

What the Data Says About ATL to ILM

The Atlanta to Wilmington corridor (ATL → ILM) covers roughly 377 miles and is served by 12 carriers, based on Bureau of Transportation Statistics reporting. Across 7,446 flights in the dataset, this route posts a 88.9% on-time rate with an average delay of 68.7 minutes when flights run late. Over the most recent 24 months of BTS data, 2,432 flights were recorded on this pairing — 18 cancelled (0.7%) and 3 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 12 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 7,446 total flights analyzed, the 88.9% on-time figure is statistically meaningful rather than a small-sample fluke. The 68.7-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, Oct 2024 posted the best performance on this corridor at 96% on-time, while May 2025 came in at 64% on-time — a 32-point gap between best and worst recent month. For travelers evaluating the ATL to ILM route, the combination of a 88.9% on-time rate, 68.7-minute average delay, 0.7% recent cancellation rate, and 12 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
