Many non-US airlines offer a premium economy product,which has become considerably more popular over the years. As economy seats retain getting tighter and business lesson seats retain getting more spacious, there's room for some middle ground between the two cabins.
Premium economy typically consists of wider seats with more legroom, and in many cases extra amenities and better service.
Interestingly no US airline has adopted a true premium economy product,though. Instead US airlines largely have "extra legroom" seating, whereby you can pay extra for seats with additional legroom which are otherwise identical (apart from for Delta, and which is slowly differentiating their extra legroom seating).
AusBT has a post with a quote from American's CEO,Doug Parker, approximately the opportunity of them adding a premium economy cabin:The post Will American Introduce Premium Economy? appeared first on One Mile at a Time.
