Plan for delays and bring a small travel bag.
JánosFlew with Alaska Airlines-Apr 2025
Self check in is not indicated well if you approach Terminal 1 from Terminal 2 Parking. Go to the other side of the checkin counters.
MichaelFlew with Hawaiian Airlines-May 2025
Budget extra time if you're flying Hawaiian Air to get from the main terminal to the remote Hawaiian Air terminal.
Verified travelerFlew with Hawaiian Airlines-Jul 2024
Check in early, give yourself a bit of time, and enjoy the flight. Lihue has a super small airport, so not much going on there.

FAQs - booking Kaua'i flights

  • What’s the best airport on the West Coast to fly to Kaua’i?

    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.

  • What’s the best airport in the San Francisco Bay Area to fly 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.

  • Which airport in Phoenix do I choose to fly to Kaua’i?

    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.

  • Which airport in New York should I choose to fly to Kaua’i?

    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.

  • How does KAYAK find such low prices on flights from the United States to Kaua'i?

    KAYAK is a travel search engine. That means we look across the web to find the best prices we can find for our users. With over 2 billion flight queries processed yearly, we are able to display a variety of prices and options on flights from the United States to Kaua'i.

  • How does KAYAK's flight Price Forecast tool help me choose the right time to buy my flight ticket from the United States to Kaua'i?

    KAYAK’s flight Price Forecast tool uses historical data to determine whether the price for a flight from the United States to Kaua'i is likely to change within 7 days, so travelers know whether to wait or book now.

  • What is the Hacker Fare option on flights from the United States to Kaua'i?

    Hacker Fares allow you to combine one-way tickets in order to save you money over a traditional round-trip ticket. You could then fly from the United States to Kaua'i with an airline and back with another airline.

  • What is KAYAK's "flexible dates" feature and why should I care when looking for a flight from the United States to Kaua'i?

    Sometimes travel dates aren't set in stone. If your preferred travel dates have some wiggle room, flexible dates will show you all the options when flying from the United States to Kaua'i up to 3 days before/after your preferred dates. You can then pick the flights that suit you best.
