Question for the experts. My LHR to SEA flight in December (BA49) just got changed to from a 787-10 to a 787-9. I am One World Emerald so can select Club World seats for free. 7K was available so I selected that for my wife. (We don't care about sitting together.) However, 7A was already taken. If you wanted a seat with isle unrestricted aisle access and within several rows of 7K, would you chose 7E, or an aisle in Row 6? Would you move back to the larger cabin to get 13A & 13J? Thanks for the help.
