You know how you really hate the process of boarding a commercial airliner? You gotta stand in line while airline staff sorts the haves from the have nots: "If you're a double-triple-gold-platinum-silver-and-ruby member please cut to the front of the line!"
15 minutes later you stand toe-to-toe in the aisle of the plane. You're in a traffic jam while Joe Six Pack attempts to stuff a full sized Samsonite into the overhead bin... Well, guess what? The airlines want you to board faster!
