I wonder which genius came up with this one? A dinosaur manager from the 80's or a junior accountant looking for a promotion who has never flown?

In addition to the crazy security lines, the impact on turnaround time and delay has to be significant. How many times have you left on time when there was a full flight with people looking for overhead space? Forcing everyone to carry on will require more gate-checking...oh I'm sorry sir, we ran out of overhead space, there's no room left in the closet either, let me gate check that for you. (Will that be 15$ too?) Maybe you can shove it in the galley, it's not being used for food/drinks or anything else either.

What's next, pay toilets?
