Hilo to Honolulu

What the Data Says About ITO to HNL

The Hilo to Honolulu corridor (ITO → HNL) covers roughly 216 miles and is served by 2 carriers, based on Bureau of Transportation Statistics reporting. Across 33,567 flights in the dataset, this route posts a 88.1% on-time rate with an average delay of 53.3 minutes when flights run late. Over the most recent 24 months of BTS data, 12,765 flights were recorded on this pairing — 104 cancelled (0.8%) and 1 diverted (0.0%). 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 33,567 total flights analyzed, the 88.1% on-time figure is statistically meaningful rather than a small-sample fluke. The 53.3-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 Dec 2025 came in at 77% on-time — a 17-point gap between best and worst recent month. For travelers evaluating the ITO to HNL route, the combination of a 88.1% on-time rate, 53.3-minute average delay, 0.8% recent cancellation rate, and 2 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
