In response to criticism of its long haul Economy Class, (and in addition, the well known concerns about the J Class product, not mentioned in the attached article), CX is to launch a new long haul product from December, over a two year period. The existing Y Class will be moved to the short haul A330 and 777 fleets.
CX will also introduce a new Premium Economy class product.
