If you’re looking for the airport with the most options of airlines and you don’t mind the crowds, then Los Angeles International Airport is the best airport to fly from the West Coast to Kaua’i. However, if you prefer an airport that’s not as busy and that also offers regular flights to Kaua’i, then the Seattle-Tacoma International Airport (SEA) is a better option. This airport has the additional benefit of being a hub for Delta and Alaska Airlines, which both operate regular flights to Kaua’i.

If you want to beat the crowds of San Francisco International Airport and have the choice of flights operated by more than one airline, then the Oakland International Airport is the best option. Both Alaska Airlines and Hawaiian Airlines operate nonstop flights to Kaua’i from this airport. If you don't have an airline preference and would prefer to fly out of a smaller airport, then the San Jose International Airport (SJC) is the best decision. Keep in mind, though, that Oakland is closer to San Francisco than San Jose is, and easier to get there by car or public transportation.

If you want to fly nonstop to Kaua’i and don’t need many airline options, then consider the fact that American Airlines has regular flights from Phoenix International Airport (PHX). If you don’t mind one layover, you can choose a flight to Kaua’i from Phoenix International Airport on another airline, like Delta or United Airlines via San Francisco or Los Angeles. Flights from Phoenix-Mesa Gateway Airport (AZA) aren’t as frequent and usually involve two layovers, so this is not the most convenient airport.

All flights to Kaua’i from New York take at least half a day of travel and require at least one layover. If you’re looking for the fewest layovers possible, you can fly out from John F. Kennedy Airport or Newark Liberty International (EWR). Flights from LaGuardia International Airport (LGA) usually have two layovers.
