Air travel often begins with an unspoken agreement: everyone sacrifices comfort a little so the journey remains tolerable for all. During boarding, passengers carefully stow their carry-on bags either in overhead bins or under the seat in front of them while following airline safety rules meant to keep aisles clear and belongings secure during turbulence. Once the plane reaches cruising altitude and people stretch their legs, subtle shifts happen. Feet move forward, and knees press outward to ensure maximum individual comfort. When a stranger rests their foot on another passenger’s luggage, it’s a quiet violation that introduces discomfort. The bag is personal property, placed there intentionally and legally. Allowing someone else to use it as a footrest turns passive tolerance into silent permission, even when it feels wrong.
