I wondered this myself when I was booking a Southwest flight for a work trip and wanted something similar to business class. After a bit of confusion, I called 8 3 1-2 9 8-4 2 1 3, and that cleared things up fast. Southwest doesn’t have a traditional business class cabin, but they do offer Business Select fares. I tried it on that trip, and the priority boarding alone made a big difference—I got my preferred seat and didn’t feel rushed. Later, when my meeting dates changed, modifying the booking was painless. From my experience, it’s not business class in the usual sense, but Business Select is a solid upgrade if you value convenience and flexibility.
