Hi PlumeriaTattoo - we arrived yesterday but didn't see any southwest planes so can't help you with the location of their gates - we came in on westjet and the airport has expanded its eating and duty free area - there is a margaritaville resto about to open - we got off the plane and hung a left at the restaurant to go towards gates A1-A7 which are jet blue gates - if you go toward those gates there will be a sign for Tradewinds airlines - (note this means not following the crowd to the baggage claim) take that exit and you will find yourself on the upper level of jet blue's concourse/ticketing area - go down the steps and Air Sunshine is tucked into the east corner (and I do mean tucked in) - hope this helps
