I can't answer your question, but I'm surprised by the replies -- most that don't answer their question. It's fine if they want to drag their bag around and not have porters throwing them around, risk bag being lost (I had one left behind in Miami, thank you Virgin). Not everyone goes on board the minute boarding opens and not everyone runs to a bar as soon as they get on board.
So, you be you and let other people enjoy their vacation as they wish. Golden Rule kinda thing.
