Honolulu to San Diego

What the Data Says About HNL to SAN

The Honolulu to San Diego corridor (HNL → SAN) covers roughly 2,614 miles and is served by 11 carriers, based on Bureau of Transportation Statistics reporting. Across 7,924 flights in the dataset, this route posts a 81% on-time rate with an average delay of 56.0 minutes when flights run late. Over the most recent 24 months of BTS data, 3,275 flights were recorded on this pairing — 28 cancelled (0.9%) and 19 diverted (0.6%). Those baseline metrics tell you what to expect before you book.

Having 11 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 7,924 total flights analyzed, the 81% on-time figure is statistically meaningful rather than a small-sample fluke. The 56.0-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, Feb 2024 posted the best performance on this corridor at 92% on-time, while Dec 2025 came in at 59% on-time — a 34-point gap between best and worst recent month. For travelers evaluating the HNL to SAN route, the combination of a 81% on-time rate, 56.0-minute average delay, 0.9% recent cancellation rate, and 11 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
