Honolulu to Kona

What the Data Says About HNL to KOA

The Honolulu to Kona corridor (HNL → KOA) covers roughly 163 miles and is served by 2 carriers, based on Bureau of Transportation Statistics reporting. Across 41,330 flights in the dataset, this route posts a 87.8% on-time rate with an average delay of 51.3 minutes when flights run late. Over the most recent 24 months of BTS data, 15,534 flights were recorded on this pairing — 142 cancelled (0.9%) and 8 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 2 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 41,330 total flights analyzed, the 87.8% on-time figure is statistically meaningful rather than a small-sample fluke. The 51.3-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 95% on-time, while Jan 2024 came in at 79% on-time — a 16-point gap between best and worst recent month. For travelers evaluating the HNL to KOA route, the combination of a 87.8% on-time rate, 51.3-minute average delay, 0.9% recent cancellation rate, and 2 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
