I wonder if any of you ever tried sitting on the aisle. It’s a hazard there, constantly being hit by anything and anyone who passes by. No way I’m “resting” on that armrest and therefore I’ll lean towards the middle seat.
Aisle lets you get up anytime you want, but also forces you to get up twice as much as the middle seat. But mainly in the middle seat you never have to be afraid of people bumping into you, which affects you for most of the flight.
