Southwest Airlines flights from California to Hawaii for as low at $49 one-way

Southwest Airlines is launching their service from California to Hawaii with fares as low as $49 one-way.

Southwest Airlines plans to begin long-delayed service to Hawaii on March 17 with a flight from Oakland, California, to Honolulu. An airline spokesman said Monday the inaugural flight was already sold out.

Through March 5, one-way flights between Oakland and the Hawaiian Islands and Kahului and the Islands are available for purchase for as low as $49.

One-way flights between Honolulu and Kahului are also available for purchase through March 5 for as low as $29.

The airline begins flights to Kahului Airport on the island of Maui on April 7. Eventually it plans to serve four airports in Hawaii from Oakland, San Jose, Sacramento and San Diego.

The Dallas company plans to start daily inter-island hops between Honolulu and Kahului on April 28 and between Honolulu and Onizuka International Airport on Hawaii Island on May 12.

Southwest wanted to sell Hawaiian flights last year, but it took longer than expected to gain approval from the Federal Aviation Administration. That process was further delayed by the 35-day government shutdown that began late last year.
