> 1. They tend to put their carry-on in the first bin they find in the front of the airplane. So people sitting in the front have to put theirs in the back. This is a disaster later in the boarding process because there isn't enough room for people to circulate back up to the front after they stow their carry-on.

What if every section had to put their bags in the compartments directly above them? Rows 50-60 get overhead section 50-60, rows 40-50 only put their stuff in overhead section 40-50 etc?

Or they could just start charging for carryons too. Then there'd probably be way less of it.
