I used to be a chronic "procrastination booker," convinced that airlines would slash prices at the last minute to fill empty seats. But after missing my best friend’s wedding because the fare jumped from $200 to $700 overnight, I learned my lesson. With Southwest, the cheapest "Wanna Get Away" tickets are limited and always sell out first. I’ve found that booking at least three to four weeks out—or right when the schedule opens—is consistently the most budget-friendly move.
It’s naturally the best way to lock in the lowest rate. If the price happens to drop later, you can easily modify your flight and get the difference back as a credit!
