Tips for this route

  • Delta, Alaska and Hawaiian all fly HNL to SEA nonstop, so compare the total with bags before picking the lowest base fare: the difference between a basic and a standard economy ticket is often less than one checked bag each way.
  • January 2027 is the cheapest month to fly over the next six months, with round trips from $235; September 2026 is the most expensive at $301 and up, a difference of $66 per traveler.
  • Departing on a Wednesday averages 20% less than a Sunday on this route. If your dates are flexible, shift the outbound by a day or two and check the calendar view before you book.
  • Fares on this route are usually lowest 4 to 8 weeks before departure and rise sharply inside two weeks.
  • Seattle is 3 hours ahead of Honolulu. Expect to lose 3 hours on the clock heading east, so an overnight or late-afternoon departure tends to arrive at a more usable hour.

Destination guide

Seattle: Coffee, mountains and Puget Sound

Seattle is the Pacific Northwest's gateway: Pike Place Market, the Space Needle and ferries across Puget Sound, with Mount Rainier and the Olympic Peninsula a couple of hours away. Sea-Tac is a Delta and Alaska hub with light rail downtown.

Best time to visit: July–September is dry, sunny and gorgeous — and the most expensive. May–June and late September are good compromises. October–April is gray and drizzly but cheap.
