The window seats in rows 16 and 32 are my favorite coach seats on the 772. Not sure why folks prefer the aisle seats in those rows, because 1) sleeping seems easier when there's a wall to lean on; 2) people tend not to congregate near the window seats in 32; 3) the carts and other folks never bother you, and 4) there's no issue climbing over people in order to get out and roam the halls, especially in row 32.
