Most long haul airlines these days offer a Premium Economy product - QF, BA, VS, VA, NZ to name a few. Is it not time for CX to follow suit and introduce a Premium Economy (Y+) class to fill the broad gap between the levels offered in Y and J? I think this would be especially useful on ultra long-haul routes such as HKG-YYZ and HKG-JFK.
I don't know about everyone else, I wouldn't want to be stuck in Y for 16 hours.
On the same note, does anyone know why CX hasn't introduced one with their cabin upgrade?
