This deal is available from Newark to Kauai (LIH) on one of the highest rated domestic carriers, Alaska Airlines. Multiple dates are available in April and May. Here’s an example from April 18th-26th:
This is one of the cheapest deals I’ve ever seen from the East Coast to Hawaii and the fact that it’s on arguably one of the top two domestic carriers in the U.S. makes it an added bonus. I didn’t see this deal on the Chase portal using UR points so it might not last very long.
