I have seen most people with carry ons jumping up before the plane stops to get their carry on with no consideration of others.

The bins are too lagre and should be smaller to allow more head room for passengers during turbulence. Carry ons should be strictly regulated by size and wieght.

Not in terms of overhead luggage.

Few enforce any restrictions. I’ve been on flights where a passenger had televisions, microwaves, and other large items sitting on not just one but two additional seats besides his or her own seat, one belonging to me, but the cabin crew, um, “declined” to take action.

I eventually gave in and now will carry on one bag *slightly* too big, if appropriate, or maybe a regulation-size bag and a couple of shopping bags. Earlier this year, the passenger in front of me checked in with a mountaineering backpack, a rucksack, and ordinary backpack, and a garment bag — all of which he refused to check, which the agent accepted. Then she told me I had to check my lone, smaller-than-allowed-bag. I refused, but it was only when I began to [politely] raise cane after placing my bag in the “check-the-size” box that she relented.

I don’t want to see on-board luggage completely forbidden; I’ll be darned if I want to check in my expensive laptop, which is well below size and weight limits. But I *would* like to airlines enforce rules, unless a flight has relatively few passengers so check-in personnel can be expansive and generour. No problem in that case with me.
