Hi
I am not able to coment on the a380 but if your 777 sectors are on 3 class aircraft then row 7 is not bulkhead. There are 2 bus cabins, row 6-7 in the front small cabin row 8 onwards the rear bus cabin. The 2 cabins are seperated by a galley. I prefer row 7 as it is quiter,you get served earler, there IS a full recline to the bualkhead behind you the only drawback if you have a window seat is you only get one window and not 3. Hope this helps.
p.s. the seat map on manage my booking is the correct one...
