What is airsick bag?

An airsick bag, also known as a vomit bag or motion sickness bag, is a small, disposable bag typically provided by airlines to passengers who feel nauseous or sickened during a flight. The bag is made of lightweight, easy-to-fold material, often lined with plastic for added protection against spills. The bags may be stored in seat pocket, and are easily accessible in case of emergency. These bags are also used in other modes of transportation like buses and ships. They are essential for passengers who suffer from motion sickness or fear of flying, and help to prevent unpleasant incidents during the flight. After use, the bags are disposed of in the airplane's waste bag or bin.
