Hello - I'm selecting seats for the MU588/MU587 flight from JFK to PVG - the plane is the 777-300. I've taken the flights before, but this time around, it appears that the smaller cabin seats (6L, 7D, 7H, 7L) seats are now available. Out of these 4 seats, which are most desirable? The 7L is right next to the lavatory, so not sure there will be any odor / discomfort in that seat. 7D and 7H are right behind the galley. Any thoughts?

All other 6 and 7 seats are showing as 'blocked' - any way to book those?
