Premium economy class, also known by brand names which vary by company, is a travel class offered on many airlines. It is usually positioned between standard economy class and business class in terms of price, comfort, and available amenities. On December 12, 1992, EVA Air introduced the Economy Deluxe Class (later renamed Evergreen Deluxe, then Elite Class, and finally Premium Economy Class) on the inaugural flight of its first trans-Pacific route (TPE-LAX), becoming the first airline to offer this class of service.[1][2] In some countries, this class has emerged as a response from governments and companies requiring economy class for travel done by staff, while still getting some benefits like airport priority.
