To me this (catering change, business light without lounge and other amenities, etc.) looks as calculated and conscious decision to get AY's euro-C product more akin as SK Plus is, i.e. premium economy.

As we know, this idea that AY would like to get rid of European business class and replace it with a premium economy product is not completely new here on FT. Previously euro-C's existence has been justified by AY's long-haul connections to Asia. Well, for the moment those connections and that business model are long gone so what would be a better time to revamp the whole airline?
