These prices aren't quite as low as the $98 roundtrip flights that were for sale this spring when Southwest first started selling tickets to Hawaii, but you may want to book these quickly if you want to travel on Southwest to Hawaii next spring.

These fares include a carry-on bag, a personal item, and 2 free checked bags up to 50lbs/23kg each.

Seat Assignments

Southwest has an open seating policy, which means there are no assigned seats and you'll get to choose your seat during boarding. The order of boarding is determined by the time of check-in so check-in exactly 24 hours before departure or pay for priority boarding for a better choice of seat.

Alternate Fares

Other airlines may start to match prices in some markets, but all other airlines charge for checked bags—some even charge for carry-on bags. Southwest has the advantage of two free checked bags and no change fees.

If you want to fly into one island and back from another, you can purchase one-way flights for about half the roundtrip price and combine with $29-$59 interisland Southwest flights.

And if you're looking for flights from further east, you'll have to wait until Southwest begins flying overnight (red-eye) flights. Until then, it is not possible to make an onward connection flying from Hawaii to points east on Southwest. You may be able to book a one-way flight from the Midwest or East Coast to Hawaii on one itinerary, but the return flight would require two separate tickets and an overnight stop on the West Coast.

For a complete list of deals to Hawaii, have a look at all of our fares on all airlines to Honolulu (HNL), Maui (OGG), Kauai (LIH), and Kona (KOA).
