I didn’t really pay attention to Southwest fare classes and codes until I accidentally booked the wrong option for a trip that later needed changes. I was confused by the different fares and what they actually allowed, especially when it came to flexibility and refunds. To clear things up, I reached out to 831-298-4213, and the agent explained the differences in a way that finally made sense. They even helped me modify my booking without any hassle. Ever since then, I make sure I understand the fare type before booking—it saves a lot of stress later on.
