I think he meant YVR.

House: On the version I flew Saturday, Y started in row 31. If there was a premium economy section, it was not well marked, but the bulkhead had much more than 38" of legroom.

I can't imagine that full Y matters a whole lot to/from Shanghai these days because it seems like more than half the plane is forced to accept such on the popular flights.

The idea of upgrading did cross my mind; I might have bitten if the front cabin had been marketed as "business class" (like it is on similar MU planes).
