Southwest Airlines started selling flights to Hawaii from California Monday morning.
The Dallas-based carrier had flights starting at $49 one-way from Oakland to Honolulu on March 18, according to its website. It's inaugural flight March 17, as well as its lowest launch fares, quickly sold out.
Southwest Airlines tweeted that it still had other low fares available.
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.
Southwest CEO Gary Kelly said in February that launching flights to Hawaii from California is the airline's priority this year, but adding flights from Nevada to Hawaii could be possible next year
Southwest applied for FAA certification earlier this year to fly to Honolulu and three other Hawaiian destinations from Oakland, San Jose, San Diego and Sacramento in California.
