Aviation Southwest applies to serve Long Beach By Robert Silk / February 11, 2016 Share 1 -- Southwest Airlines plans to begin flying out of Long Beach this year. The move would give the carrier a presence in all five Los Angeles-area airports and a total of 10 airports in California.On Thursday, Southwest said that it has applied for slot authority at Long Beach Airport, where capacity is controlled according to noise regulations set up by the city. The announcement came as Long Beach media were reporting that the city had already made decisions on the nine slots that had become available after a December study showed that cumulative noise from planes utilizing the airport had dropped. Each slot allows a carrier to operate a daily roundtrip flight. According to the Long Beach Business Journal, the city of Long Beach has allocated four slots to Southwest, three to JetBlue and two to Delta. JetBlue and Delta currently operate out of Long Beach Airport.Los Angeles International, Orange County, Ontario and Burbank are the other four airports in the greater Los Angeles area.
