San Francisco to Kona

What the Data Says About SFO to KOA

The San Francisco to Kona corridor (SFO → KOA) covers roughly 2,367 miles and is served by 3 carriers, based on Bureau of Transportation Statistics reporting. Across 5,088 flights in the dataset, this route posts a 85% on-time rate with an average delay of 65.2 minutes when flights run late. Over the most recent 24 months of BTS data, 1,556 flights were recorded on this pairing — 4 cancelled (0.3%) and 9 diverted (0.6%). 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 5,088 total flights analyzed, the 85% on-time figure is statistically meaningful rather than a small-sample fluke. The 65.2-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 2024 posted the best performance on this corridor at 98% on-time, while Feb 2024 came in at 66% on-time — a 32-point gap between best and worst recent month. For travelers evaluating the SFO to KOA route, the combination of a 85% on-time rate, 65.2-minute average delay, 0.3% recent cancellation rate, and 3 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
