Well, I do get a BIT aggravated at the the lines, too, but I can't fault SWA about it; they don't create the situation. They are always making announcements that it isn't necessary to line up before the aircraft arrives, but very few people listen.
At STL, even before the kiosks, if you wanted to get into the first boarding group, you had to arrive at least 3 hours early. (Especially for the direct MCO flights, b/c they originate in Chicago, so they always have some people on board already.) Before the kiosk/skycap distribution, the line formed at the gate desk, now that people can get the passes before security, the lines form at the actual gate railings. The lines have a tendency to block the seats in the gate area, and it does get a little old trying to sit in a chair with someone's posterior less than a foot from your face. For some reason, many people here feel compelled to try to be first in line for their boarding group, so they arrive 3 hrs. early and spend the entire time standing in line at the actual gate railings. (Just FYI, I flew to MCO on the mid-afternoon flight on 9/11/03, which was a Thursday. We arrived 1 hr & 45 minutes early, and I got the last A pass. DH & DS got B's. I saved them seats and we got a full row near the back.)
Also, as far as I can tell, AA still has 2 direct flights to MCO, one at 6:30 am, and the other at about 3 pm. SWA has 5 flights per day, 3 direct, and 2 that stop, one in Birmingham, and one in Louisville.
(If you're in Southern Illinois, wouldn't Louisville be closer than Nashville?)
