re: Do airlines even pretend to enforce carry on rules anymore?

I just returned from an international flight.

People will have standard carry-on wheeled luggage, a backpack the size of a sofa and a huge book bag or purse and cram it all in the overhead.

It is infuriating. Everything besides the carry on should go at their feet.

Coming home, the airline asked people to check their carry on for free and I volunteered for that. I don't care if my carry on is late coming home.
So I breezed to my seat with only a small backpack at my feet.
