Premium economy has been a booming seat market among airlines. This particular cabin offers an upgraded experience from the standard main cabin, but is not as luxurious as first or business class. While several travelers look for the most comfortable journey on lengthy flights, premium economy has been somewhat of a hybrid offering and is seen by many as the cheaper alternative to sitting in the front of the plane. In fact, it has become so popular that most airlines with long-haul international flights have updated the interiors of their widebody fleet to feature their version of premium economy.
