The Faceplant Position
In public, it’s rude to occupy too much space if you’re going to fall asleep. However, this woman was unable to keep her eyes open as she waited to board her flight. She was exhausted and needed to get some shut-eye. It was kind of her to take up the smallest possible space so as not to disturb the rest of the passengers.
She’s only using up two chairs. The woman in the back of the row occupied the entire row, so this one is understandable. She probably didn’t want to risk snoozing through her flight’s boarding announcement because she was so comfortable.
