Premium economy is a travel class offered on some airlines, positioned in price, comfort, and amenities between economy class and business class. In 1991, EVA Air became the first airline company that have this kind of class in aircraft.
As of 2011, the term is not standardized among airlines, and varies significantly when comparing its use on domestic versus international flights or when comparing low-cost or regional airlines with other airliners. Premium economy is sometimes limited to just a bit more leg room, but at its most comprehensive can feature multiple "creature comforts" that are only a notch below Business class.
For example, in the United States domestic market, airlines such as United, Delta, and Jet Blue have an upgraded Economy class with 2–5 inches (5.1–13 cm) more leg room as the only difference; they market the class as "economy plus", "economy comfort", and "even more legroom" (respectively). At the other extreme, on Air New Zealand and Qantas' "premium economy" and Virgin America's "main cabin select" includes more amenities such as premium check-in, large customized seats (some for couples, others targeting solo travelers), seat pitch up to 41 inches (100 cm) with 50% more recline, premium meals, a self-service bar for drinks and snacks, a personal in-flight entertainment center with remote control, noise-cancelling headphones and choices in games and movies for children and adults, skin care products in the lavatory, and an amenities pouch containing items such as socks, sleep masks, earplugs, and toothbrush.
Examples of differences 
Premium economy can encompass differences from economy class such as:
- a free upgrade to premium members of frequent-flyer program and passengers flying full-fare economy,
- a separate section of the economy/coach cabin with more legroom (36–38" seat pitch), along with some form of leg rest,
- enhanced or improved in-flight entertainment features
- dedicated cabin crew
- better seats (often with fewer seats per row, to improve shoulder/elbow room)
- at-seat laptop power
- in-seat telephone
- a lounge
- priority boarding
- exclusive amenity kits
- upgraded meals and drinks
- increased luggage allowance
Some airlines may designate an entire economy class as premium, such as United p.s. on its transcontinental Boeing 757-200 premium service aircraft. Premium Economy tickets also normally earn more mileage in an airline's frequent flyer program, attracting a bonus between Economy and Business.
Starting in October 2012, Hong Kong airline Cathay Pacific collaborated with local lifestyle store G.O.D. and introduced a new range of amenity kits for premium economy passagers. They are designed as collectibles with each bag being able to hook up to each other to form a wall-hanging accessory. The first two available are 'Joy' and 'Fortune, with designs that depicts Chinese gods relaxing inflight and of auspicious clouds respectively. The two types are available on outbound and in bound flights respectively. They include 90% recycled plastic bottles and toothbrush made mainly from biodegradable corn starch and cellulose.
