Lihue to Seattle

What the Data Says About LIH to SEA

The Lihue to Seattle corridor (LIH → SEA) covers roughly 2,701 miles and is served by 3 carriers, based on Bureau of Transportation Statistics reporting. Across 5,273 flights in the dataset, this route posts a 84.8% on-time rate with an average delay of 62.8 minutes when flights run late. Over the most recent 24 months of BTS data, 2,163 flights were recorded on this pairing — 39 cancelled (1.8%) and 3 diverted (0.1%). 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 5,273 total flights analyzed, the 84.8% on-time figure is statistically meaningful rather than a small-sample fluke. The 62.8-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 91% on-time, while Jan 2024 came in at 67% on-time — a 25-point gap between best and worst recent month. For travelers evaluating the LIH to SEA route, the combination of a 84.8% on-time rate, 62.8-minute average delay, 1.8% recent cancellation rate, and 3 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
