For the 777-300ER 77Y bkk-lhr (which also has First Class) the only seats available in business are middle aisle (interior honeymoons and aisle facing middles) and window aisle, including 12J, which is second row of the mini cabin up front behind First.

All the true window A/Ks are taken, of course, so for a solo traveler, would it be better to take 12J or perhaps go against the grain and take an interior middle and just put the partition up, or should I just stick with aisle window?
