I had to change a Southwest flight last month when a work meeting got rescheduled, and I wasn’t sure how complicated it would be. I called 8 3 1-2 9 8-4 2 1 3, and the agent guided me through the process. They helped me select a new flight, explained how my fare credit would work, and confirmed that there were no extra fees. The whole process was surprisingly simple, and I appreciated being able to speak with someone directly instead of navigating the website on my own. From my experience, calling makes changing a Southwest flight stress-free.
