The seats are assigned. People have been standing in line for 15 minutes now. Why on earth would anyone want to stand there, when they could just sit and wait until the line clears?
I understand wanting to get off a plane ASAP, but boarding? You just end up sitting on the plane, waiting for everyone else to get on.
A lot of airlines nowadays seem to charge extra for a carry on than they do a checked bag. So I tend to bring one checked bag and one small backpack that can fit under the seat, which isn’t classified as a carry on.
Yup yup, carry on and personal item. You can live for a week out of that. Plus no wait at the baggage claim, and no risk of the airline stealing or breaking your stuff.
