Yes, I printed my passes online about 5 minutes after the 24 hour point...we were the first checked in (the passes are numbered). We got to the gate about an hour or a little more before flight time. SWA is still new to Pittsburgh and not everyone lines up like they do in Orlando. So, I'd say we probably didn't jump on line until maybe half an hour before flight time, or just ten minutes before boarding, and we were first in the A line. The flight wasn't full though, and there weren't many people in the C line. There were a handful of preboarders, maybe 6 or so. It was on a Monday morning and the airport was crazy, so I was worried our flight would be full, but it wasn't. The people immediately behind us and right next to us in the B line were all returning to Florida after being here for the Steelers game.
