Oversized individuals should have to buy two seats or first class. Perhaps fit planes with half a dozen larger seats. Our row had 6 seats: In those 6 seats were 3 people over 350 pounds and two toddlers plus my wife and I. My seat changed from an aisle to a window between when we booked and when we flew. No notification of that. Apperently that hapened to accomodat one of the oversized individuals. Uncomfortable flight is an understatement.
