Have these models actually been verified experimentally? My perception is that people sitting in the back of the airplane often place their carry on in the first available overhead bin space. This creates a traffic jam as people sitting near the front walk past each other looking bin space and then back to their seat. It also presents a problem when exiting the plane as all the people in the front try to make their way back to collect their bags.
