I recently used my Southwest Companion Pass for the first time, and it was surprisingly simple once I understood the process. After selecting my flight online, I added my designated companion during checkout, and the system applied the pass so they flew for free (just taxes and fees). When I had a last-minute schedule change, I called 831-298-4213, and the agent helped me modify both my flight and my companion’s ticket without any hassle. Honestly, having that number saved me from juggling everything online and gave me peace of mind. From my experience, the key is booking your own flight first, then adding your companion, and keeping that number handy in case changes pop up. It made using the Companion Pass completely stress-free and actually fun!
