Ted is one of two airline divisional brands of United Airlines similar in concept to the Delta Shuttle or the US Airways Shuttle, but specifically targeted to compete effectively in the low cost airline market. The airline is equipped with 57 Airbus A320 aircraft, in a 156-seat all-economy configuration. The A-320 is a short-to-medium range commercial passenger aircraft manufactured by Airbus. Ted was created to give United a way to compete with low-cost airlines, such as Frontier and Southwest. Ted A320s are configured in one class that is split into two sub-classes. Economy Plus is the first sub-class which provides an extra 4 inches to the existing 31 inches of legroom for economy.
