What the Data Says About KOA to OGG

The Kona to Kahului corridor (KOA → OGG) covers roughly 84 miles and is served by 3 carriers, based on Bureau of Transportation Statistics reporting. Across 8,327 flights in the dataset, this route posts a 85.2% on-time rate with an average delay of 54.6 minutes when flights run late. Over the most recent 24 months of BTS data, 2,993 flights were recorded on this pairing — 7 cancelled (0.2%) and 3 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 3 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 8,327 total flights analyzed, the 85.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 54.6-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, May 2025 posted the best performance on this corridor at 99% on-time, while Dec 2025 came in at 83% on-time — a 16-point gap between best and worst recent month. For travelers evaluating the KOA to OGG route, the combination of a 85.2% on-time rate, 54.6-minute average delay, 0.2% recent cancellation rate, and 3 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
