I was hoping that the pendulum would swing the other way with the scandal over too many passengers bringing out their bags on a recent AA evacuation caused by a burning tire. The push to eliminate checked bags has created a chaotic cabin environment that probably exacerbated the situation. There's no sign of it getting better either. The overcrowding of overhead bins creates a prisoners dilemma where flight attendant…
(Then there's the factor of how much time and space all that also wastes at security checkpoints.)
Checked baggage has the efficiencies of forklifts and trucks and conveyor belts. Just as airlines fixed most of the problems with those systems and got them to be efficient beasts they decided to disincentivize actually using them by charging extra for what is the cheaper cargo space. I wish an airline would have the courage to reverse the fees structure and charge for overhead bin space instead. (But then I also travel with IBS issues and my patience in deplaning has been severely tested enough that I know not everyone shares quite my annoyance at deplaning issues in particular.)
