In any case, Hawaii has 7 commercial airports scattered across several islands, plus Southwest has partner airlines once again now (which was how "Southwest" got you to Hawaii the last time around), and a statement like that doesn't explain if they would fly the route themselves or take on a partner, and it doesn't explain if you could get to many islands or just one of them. (Nor, as pointed out already, does it explain what year, decade, or century this might happen in.)
