How is that even allowed from an safety point of view ?
Motivating passengers to clogg up the cabing with their luggage any more that absolutely necessary is insane.
Empty overhead bins, where stuff would be out of the way and secure.Instead have clogged up floors, just to make (or because of saving) a few $.
On high density seating, with swim wests under seat, there is hardly enough room for just you legs and feet.
Putting anything on the floor that could be stowed elsewhere is an unnecessary obstacle in case of evacuation.
Maybe COVID wil drag on long enough for that whole loco bunch to go away for good.
