I'm impressed with how many readers have commented that they haven't flown in a long time.

I have to fly twice a month if I want to spend time with my grandsons, who live across the country.

Yes, you can choose your seats online but people can't always choose the seats they want. So some of them try to "fix" that once they're on the plane.

Although you can also ask the gate agents to help you change your seat before you board.
