Are any of these seats missing a window? (I'm thinking of configurations like the 773, which is missing a window toward the back of business class - row 11 on AA's '77W' comes to mind.)
6A or K on 773. Just go for 1,3,5,8,10 A or K IMO.. I’ve had 3A and 3K for all my qsuite (darn lucky) neither close to galley nor lavatory.
