I’ve been asked this a lot because Southwest doesn’t work like most airlines. You can’t really upgrade your seat itself since there’s open seating, but you can upgrade your boarding position, which makes a big difference. I’ve used upgraded boarding before when I wanted to board earlier and grab a better seat. On one trip, my plans changed last minute and I had to switch flights, which meant rethinking my boarding option too. Calling 8 3 1-2 9 8-4 2 1 3 was the easiest way to instantly book, cancel, or modify flights without any confusion.
