I am one of those dopey heads, lining up in the A line an hour before. The last time I did it, I got to the gate about 90 minutes before our flight. I sat for a bit, and then as I saw some get into the line, I joined in. I was number 8 in line. There were a ton of preboarders. Only my dd and I were in our party, so figured there wouldn't be an issue. And there wasn't. But, remember, we were 8th in line. By the time we boarded, we had to hike back to about 3 rows behind the wing before we found a window and a middle seat together! If I had waited to board at the end of the A line my dd and I would not have gotten that configuration. So....my choice to stand in line for an hour. But unless I get a terrific fare with SW, I won't fly them. I prefer having my seat assigned, and love the tv's in front of me that I used to get with Song (and hopefully will in the future) and with JetBlue.
