Yes, I read some of the other responses after I finished posting mine. I also can recall times when I was waiting in line boarding a plane, and idiots in front of me were carrying all sorts of packages and large bags that would never fit in the overhead locker. In fact, if you didn’t board the plane early enough, you were liable to find all the overhead spaces taken by people who were bent on using two or three of them.
So, it goes both ways.
I fly frequently and am always frustrated when I am assigned a late zone, and there is no space for my carry on which fits the description in the security screening area.
So many people think “sardine class”, is first class, and the bins are available on a first come basis. I am 6’3” tall and the space under the seat is valuable real estate to me as is the isle if I can get it.
Makes flying miserable when you have to deal with the entitled and inconsiderate, which are usually one in the same.
