I booked a Y+ redemption on CX to Tokyo using BA avios for January. The plane has been changed to 2 class and my seat selection on the CX website shows me in Economy, but my BA booking still shows Premium Economy.

Should I contact CX or BA about this, or just wait for the day to come and see what happens.

Any one else experience this situation before? Based on previous posts I'm assuming I'll get moved to J, but expertflyer shows J C D and I as 0.
