On the Airbus 380 that I took from Bangkok to Dubai, every person in business class was able to have an aisle seat. There were single pods next to each window, with an aisle on the other side of those pods, and then two seats side-by-side in the middle, each with access to the aisle as well. The seats that were beside each other had the option of putting up a divider. The Airbus 380 and Boeing 777-200LR, plus the majority of Boeing 777-300ER 777 planes offer this feature, although some models do not.
