The airline, which began service to Hawaii in March, is also more than doubling the number of interisland flights, from 16 to 34, including new flights between Honolulu and Kauai and Honolulu and Hilo, on the Big Island.
Tickets for the new routes go on sale Thursday and can be booked on Southwest's website.
