About flying from Salt Lake City to Kauai

Kauai (LIH) is the least-traveled of the four major Hawaiian-island routes from Salt Lake City, and Deal Wings members who watch this route patiently catch some of the deepest Hawaiian-island deals of the year. Nonstop service is seasonal and limited; most Utah travelers connect through LAX, SFO, or SEA. Typical round-trip economy fares run $550 to $800; under $400 RT is a great deal, under $300 is an insane deal, and below $250 RT is a true unicorn fare.

Kauai's smaller airport and lower seat capacity mean that fare drops are sharper but rarer than on Maui or Oahu. When a great deal lands on this route, expect it to sell out within an hour or two.

Insider tip: Kauai seat inventory is small. The moment a great or insane deal hits this route, treat it as a sell-within-the-hour situation: book first, refine plans later.
