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.
You can stand during the flight?
Not if you’re in a middle or window seat. It’s kinda rude to make one or two people constantly get up and down.
This is why I only book aisle seats. I have more leg room and I can stand up ad sit down quickly without disturbing others in my row.
Short-haul: window seat for the view. Long-haul: aisle seat for the comfort.
