I remember wondering about the cost of upgraded boarding on Southwest after getting stuck in a late boarding group on a packed flight. From my experience, the price can vary, but it’s usually somewhere around $20–$40 depending on the route and availability. I decided to try it once on a short trip, and honestly, boarding earlier and having a better seat choice was worth it. Another time, my schedule changed and I needed to adjust both my flight and boarding option. Calling 8_3_1_2_9_8_4_2_1_3 turned out to be the best way to instantly book, cancel, or modify flights without dealing with multiple steps online.
