Alaska Airlines has just put out a jaw-dropping fare to Kauai, the greenest and most laid-back island in Hawaii. We're talking about just €581 return from Boston, which works out at almost 30% less than this route usually costs. Prices can shift, so if this one catches your eye, don't wait too long.

The dates we've found are 12 to 17 December 2026, which makes it perfect timing to swap the New England cold for white-sand beaches, dramatic cliffs and a pace of life that's hard not to fall for. The journey includes one stop, which is typical for routes to Hawaii from the East Coast.

Kauai is ideal for anyone who wants nature in its rawest form: jaw-dropping cliffs like those at Kalalau, trails straight out of a movie in Waimea Canyon, or simply a beach where you can relax with a piña colada. You can also explore charming small towns such as Hanalei and Kapaa.

Keep in mind that the price may change when you go to book, so we recommend checking availability right away. Deals like this tend to disappear quickly.
