Kahului to Seattle

What the Data Says About OGG to SEA

The Kahului to Seattle corridor (OGG → SEA) covers roughly 2,640 miles and is served by 5 carriers, based on Bureau of Transportation Statistics reporting. Across 9,903 flights in the dataset, this route posts a 78.2% on-time rate with an average delay of 64.9 minutes when flights run late. Over the most recent 24 months of BTS data, 3,555 flights were recorded on this pairing — 69 cancelled (1.9%) and 22 diverted (0.6%). Those baseline metrics tell you what to expect before you book.

Having 5 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 9,903 total flights analyzed, the 78.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 64.9-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 2025 posted the best performance on this corridor at 88% on-time, while Oct 2025 came in at 71% on-time — a 16-point gap between best and worst recent month. For travelers evaluating the OGG to SEA route, the combination of a 78.2% on-time rate, 64.9-minute average delay, 1.9% recent cancellation rate, and 5 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
