Southwest Airlines A - B - C

Southwest Airlines offers "A" seating where the passenger is allowed to board the plane first. In this initial group there is the best chance that you will get premier sitting of your first choice and have a comfortable trip to your destination. What gives me cause to wonder, though, is when the fellow passengers, who will be joining me in the 2 hour trip, will stand in the "A" line for 2 hours to ensure they have the very first choice in comfortable seating for the 2 hour flight.... it just makes me wonder...
