Re:dual boarding more efficient? (Score 1)

If humans were rational we could do something like "anyone seated in an aisle seat with nothing in an overhead bin can disembark now". This would stop the overhead bin addicts from jumping up and blocking the aisle throughout the length of the plane (as soon as|before) it stops rolling. Then you have extra room that the binners could use to more efficiently step on people, drop bags on the heads of patiently-waiting others, etc.
