Expanded Information
It is a sales strategy of various airlines to increase the occupancy rate by paying the full price or even a discounted price of the economy class, that is, to enjoy the treatment of first class. This is a sales tactic used by airlines to increase ridership. All airlines have now introduced this type of cabin, with Hainan Airlines, China Eastern Airlines, China Southern Airlines and Air China offering this type of cabin.
Because this service is just a restructuring of the upper seats of the airplane, the airlines call this class differently, but the content is similar, for example, China Eastern Airlines calls it Value First Class, while Hainan Airlines defines it as Discount First Class! HNA's Premium First Class (Value First Class) is the ability to fully enjoy first class service.
