What the Data Says About SJC to OGG

The San Jose to Kahului corridor (SJC → OGG) covers roughly 2,355 miles and is served by 9 carriers, based on Bureau of Transportation Statistics reporting. Across 5,180 flights in the dataset, this route posts a 86.6% on-time rate with an average delay of 58.2 minutes when flights run late. Over the most recent 24 months of BTS data, 1,105 flights were recorded on this pairing — 6 cancelled (0.5%) and 1 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 9 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 5,180 total flights analyzed, the 86.6% on-time figure is statistically meaningful rather than a small-sample fluke. The 58.2-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, Jul 2025 posted the best performance on this corridor at 100% on-time, while Feb 2024 came in at 69% on-time — a 31-point gap between best and worst recent month. For travelers evaluating the SJC to OGG route, the combination of a 86.6% on-time rate, 58.2-minute average delay, 0.5% recent cancellation rate, and 9 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
