Southwest Airlines extended its schedule today and has a slew of new routes with the new schedule extension. The most exciting news is new nonstop service between Sacramento (SMF) and Maui (OGG) and the earlier November start of Southwest's nonstop flights between Sacramento and Honolulu (HNL). With more flights to Hawaii, fares on Southwest are low from several cities once again. Book quickly because these low fares sell out in a flash! Fares from the mainland to Hawaii are as low as $99-$178 one-way or $198-$356+ roundtrip.

Southwest Adds New Flight to Maui from Sacramento and Starts Honolulu Service Early

Southwest is also beefing up its new flights from Oakland (OAK) and San Jose (SJC) to Lihue, Kauai (LIH) and Kona (KOA). Nonstop service, which begins in late January, will switch from 3-4 days/week to daily service on March 7, 2020. The switch to daily service means that there are now more connecting flight options to these Hawaiian islands from other cities on the mainland.

And similar to Southwest's decision to start Sacramento - Honolulu service in November, interisland flights between Honolulu (HNL) and Lihue, Kauai (LIH) will now also start November 10, 2020. Along with the announcement, Southwest is selling tickets as low as $29 one-way or $58 roundtrip for all nonstop interisland service.

Daily nonstop service now begins on November 10, 2020, on the following routes:

Connecting service and low intro fares are also available to the new destinations in Hawaii from a few cities in the Western United States and also on interisland flights within Hawaii. Existing connecting flights have low fares once again with the schedule extension.

All fares also work in the reverse direction and this is not a complete list of Southwest deals to Hawaii.

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 this spring. Southwest fares to Hawaii have remained extraordinarily high whenever its newly released low fares sell out.

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.
