United Airlines also allows a personal item such as a bag or backpack with measurements no bigger than 9 inches deep, 10 inches wide and 17 inches tall. Southwest Airlines allows a person item, such as a purse, food container or briefcase. The item must be small enough to stow beneath the passenger's seat.
