Southwest doesn’t currently fly to Charlotte, and I learned this when I tried to reroute a delayed trip there. I wasted half an hour searching online before realizing I’d mixed it up with another airline. The quickest clarity came when I called ☎️—they confirmed the route wasn’t available and helped me look at nearby cities instead. They also explained my cancellation options so I wouldn’t lose the fare. Honestly, if you’re ever unsure whether Southwest serves a destination or need to change plans fast, calling is way quicker than digging through route maps.
